Generac vs. Briggs & Stratton

From minor thunderstorms to natural disasters, power outages are inevitable. They are potential dangers every homeowner should prepare for, and we’re here to help. Loss of electricity can be a frightening and potentially dangerous event, but it does not have to be. Choosing the right standby generator will help to ensure that your home has access to appliances and outside communications when the power fails. At first glance, choosing a standby generator may seem like a daunting task. There are several brand options on the market, but not all generators are created equal. In this article, we will discuss our two most popular and recommended models from Generac and Briggs & Stratton. Built to last, these standby generators provide the best performance for homes of all sizes in Fairfield County.

Some Factors that Differentiate Both Brands


Generac’s unique enclosure is distinctive and easily recognizable. The beige box with an orange logo is made from durable aluminum material and will last for years to come. The Briggs and Stratton company’s enclosures are made of automotive-grade Galvanneal steel. These enclosures are rust-resistant  and every bit as rugged as they look.


A Generac standby generator will cost a little more than its Briggs & Stratton counterpart. Both are sturdy and well-built, but the Generac option is typically equipped for better performance than the Briggs-Stratton alternative.

15000 Watt generator

For construction crews and those who like to live off the grid, there are larger generators available to produce up to 15,000 watts of power.

This is more than enough to power multiple large appliances, RVs, large tools, and more.

With each of these generators, you will get a wide variety of outlets and feature selections to make sure that you get the best generator for your needs.

Today, I am going to look at a few of the best 15,000 watt generators on the market and how they can benefit your specific needs.

Table of Contents

1. Duromax XP15000E

As one of the largest brands in the generator industry, it is no surprise to see Duromax on the list of 15kw generators. Duromax is known for producing some of the most durable and reliable generators used both commercially and residentially.

This Duromax XP15000E is a great example of a high powered generator that can be used both at home and on the job site.

xp15000e generator in a pick up trunk


The Duromax XP15000E is going to produce 15,000 starting watts and 12,000 running watts from the 713cc V-twin engine.

This engine produces 23 horsepower and has an operating volume of 74 dba which is pretty standard for most generators.

It is designed to handle heavy loads from construction or residential lights, refrigerators, home air conditioning units, and power tools with high amperage ratings. I would not hesitate to rely on this generator for home backup power, complete RV electrical reliance, or powering a complete jobsite.

Outlet Selection

Take a look at the outlet selection on the Duromax, you will see that you have plenty of options to make use of the full 12,000 running watts.

While I would have loved to see covered outlets, the number of outlets available makes up for this small setback.

On this generator, you will get to choose from 4 120V 20A GFCI outlets, 1 120V 30A twist lock outlet, 1 120/240V 30A twist lock outlet, and 1 120/240V 50A heavy duty outlet for RV use.

With so many different outlets to choose from, you will have no worries about plugging up just about any appliance or tool to this generator.

Fuel Capacity & Run Time

The XP15000E is equipped with a 10.8-gallon fuel tank to allow for up to 8.83 hours of use at 50% load. This is a great run time as it will allow you to get a full day’s worth of use from your generator without having to worry about refilling it.

Stand Out Features

While this generator does not have any crazy standout features, you will get the benefit of surge arrest and a digital multimeter to keep track of your generator’s vitals.

As with most larger generators, this generator does come with wheels and collapsible handles for easy transportation.

IMHO: In My Humble Opinion
When it comes down to making a purchasing decision, you can’t go wrong with a Duromax generator. This generator has just about everything you could want from a generator that is built to get the job done without dealing with any extra bells and whistles.

2. Generac 5734 GP15000E

Generac is a well known generator manufacturer and has been producing some of the largest stand by generators for years.

If you have been shopping around for a portable generator, you have most likely seen their name come across as they offer many different sized generators to fit specific customer’s needs.

Today, I am going to look at the Generac 5734 generator, a 15kw generator that can help give you the power you need.


The Generac GP15000E generator is going to give you 15,000 running watts and a very impressive 22,500 starting watts to allow for unbeatable power in its class.

The high starting watt capacity allows for larger tools and appliances to be used with this generator.

The 992cc Generac engine was designed specifically for generators and features a pressurized lubrication system to send oil directly to critical areas of the engine. It has an electric start to help make this generator much easier to use.

Outlet Selection

The Generac GP15000E generator has one of the widest selections of outlets out of all of the generators on this list.

This makes this generator versatile in using up the 15,000 running watts.

Looking at the control panel, you can see that the outlets are laid out perfectly to ensure that you will have no problem hooking up just about anything to this generator.

Take your pick from 2 120V 20A 5-20R outlets, 2 120V 20A 5-20R GFCI outlets, 2 120V L5-30R 30A twist lock outlets, 1 125/250V 30A l14-30R twist lock outlet, 1 125/250V 14-50R outlet, and a 12VDC 10A outlet.

This is one of the best selections I have personally seen with a generator, which makes this Generac very impressive.

Fuel Capacity & Run Time

The Generac GP15000E is going to come equipped with a large 16 gallon fuel tank that will allow for up to 10 hours of runtime at 50% load.

You will also get a built-in tank fuel gauge and fuel filter for easy maintenance.

Stand Out Features

This generator is all business and doesn’t feature many stand out features.

You do get electric start, wheels, and a handle that is built into the frame which makes this generator much easier to use.

IMHO: In My Humble Opinion
This generator is most likely going to be best suited for someone who is going to be using high wattage appliances or tools where starting watts are an important factor. Your average homeowner will most likely not need 22k starting watts for most back-up power supplies. However, if you are using it to live off the grid, this could be a great generator to use.

3. A-iPower SUA15000EC SUA15000E

As one of the lesser-known brands on this list, A-iPower has been making a great name for themselves in the generator industry.

If you have been following along on some of my other blogs on smaller generators, you may have seen their name pop up a few times as they have quickly become a more well-known brand.


The A-iPower SUA15000EC portable generator is going to be powered by a 680cc OHV twin-cylinder engine that produces 24 horsepower.

This is going to allow this generator to make 15,000 starting watts and 12,000 running watts, putting it right on par with the other generators on this list.

This generator is designed to run many household appliances at the same time, making it ideal for home back-up power.

Outlet Selection

At first glance on the SUA15000EC, I was thoroughly impressed to see covered outlets.

This is a feature I had hoped for on some of the higher end brands, but seeing it on the A-iPower lets me know that they are in tune with what the industry wants.

Under the hard plastic, snap-in outlet protectors are 5 outlets to allow you to plug in multiple appliances or tools.

You will get 2 GFCI 120V 20A 5-20R outlets, 1 120V 30A l5-30R outlet, 1 120V/240V 30A l14-30R outlet, and a 120/240V 50A L14-50R outlet.

Fuel Capacity & Run Time

The SUA15000EC generator is going to feature an 8-gallon fuel tank to allow you to get up to 7 hours of runtime at 50% load and 5 hours of runtime at 100% load.

Stand Out Features

The biggest stand out feature on this generator is going to be the outlet protectors which help to block out moisture, dirt, and debris from destroying your generator.

You will also get a 4 wheel system to make moving the generator easy, however, these wheels are rather light duty, so moving it through a job site may require lifting.

This generator also has an electric start feature which is always a plus.

IMHO: In My Humble Opinion
While this generator has great outlet selections and some great features, the wheels on this generator are going to greatly limit the mobility, especially in grass and dirt. This generator will be great for those who plan on keeping it strapped down somewhere or moving it on a flat, solid surface, but for those who need to move it around on a softer terrain may look at other options.

4. Westinghouse WPro12000

Westinghouse is no stranger to any of my lists as they produce some of the best generators on the market in a wide variety of power levels.

When looking at 15kw generators, the Westinghouse WPro12000 was an easy choice as I have had great luck with any Westinghouse generator I have used in the past.

WPRO 12000 Generator


This Westinghouse generator is going to come equipped with a 713cc Westinghouse V-Twin engine with a cast iron sleeve to help produce 15,000 starting watts and 12,000 running watts.

With their own line of generator specific engines, Westinghouse engineers have thoroughly tested their engines for maximum performance in their generators.

This generator used clean power and is safe for electronics with less than 5% THD. Is also has Smart Idle to allow for automatic efficiency idling.

Outlet Selection

Like many of their other portable generators, Westinghouse has equipped this generator with full GFCI outlets and protective plastic outlet covers to keep your outlets protected from dirt, debris, and moisture.

The WPro12000 generator is going to feature 2 5V USB ports, 4 120V 20A 5-20R outlets, 1 120V 30A L5-30R outlet, 1 120/240V 30A l14-30R outlet, and a 120/240V 50A L14-50R outlet.

While most of these outlets are found on many of the generators on this list, the two USB ports are a nice change of pace and allow for quick charging of smaller electronics.

Fuel Capacity & Run Time

The generator is going to come with a built in 10.5 gallon fuel tank to allow for a 16 hour run time at 25% load or 11 hours at 50% load. This will ensure that your WPro12000 can keep your appliances running throughout the day without having to worry about refilling.

Stand Out Features

Westinghouse is known for its standout features and this generator is no different. It includes covered outlets, an easy to use electric start, a digital data center, full panel GFCI, and built in wheels/handle for easy transportation.

IMHO: In My Humble Opinion
There has never been a Westinghouse generator that I have never been reluctant to stand behind. This WPro generator is a great example of a generator that can be easily used both commercially and a residential backup power generator. It has many great features along with a superb outlet selection that makes it easy to use this generator for just about anything.

5. Champion 100111

Another large brand in the generator industry, Champion, makes its way onto this list with its 100111 generator.

Champion has been a leader in the industry for years and produces many different sizes of generators to suit many different needs. Today, I am going to take a closer look at the 100111 and see what makes it one of the best 15kw generators.

100111 15kw generator


The Champion 100111 generator come equipped with the tried and true 717cc V-twin Champion engine.

This engine includes a battery powered electric start that can be turned on with the simple push of a toggle switch. It helps make 12,000 running watts and 15,000 starting watts for both commercial and residential use.

Outlet Selection

Champion is very well known for doing a great job pairing up their outlet selection with the power levels on their generators.

Often times, you will see generators with large amounts of wattage capacities and a lackluster selection of outlets.

This generator further proves that Champion has their ear to the ground on which outlets consumers want on their generators.

With the Champion 100111, you will notice that all of the outlets are protected by plastic, snap in protective covers which is a huge plus, especially on dusty job sites. These outlet protectors cover one 120V 30A locking outlet, a 120/240V 30A locking outlet, a 120/240V 50A outlet, and four 120V 20A GFCI outlets

Fuel Capacity & Run Time

You can expect to get about 10 hours from the 5.9 gallon fuel tank on this Champion generator. This should help get you through the workday on a single fill-up.

Stand Out Features

This generator’s most standout features are going to be protected outlets, electric start, foldable handles, built in wheels, a volt guard to protect appliances from power surges.

IMHO: In My Humble Opinion
Champion will always be one of the best generators you can choose for both residential and commercial use. They are built tough to take on construction sites while being easy to use for homeowner use. This Champion generator is easily one of my top picks as it has a great outlet selection, is easy to use, and is easy to transport.

6. CAT RP12000E

CAT, short for Caterpillar, is not only one of the leading manufacturers of heavy machinery in the world, it is also one of the largest companies in the world.

This means that you can expect nothing less than the best from their line of portable generators, including this RP12000E generator.

cat rp12000e generator


The CAT RP12000E generator is going to feature a CAT 670CC v-twin OHV engine that has built in idle mode option and a pressurized oil system.

This ensures that this engine is going to last for years to come and will run as efficiently as possible.

You can expect 15,000 starting watts and 12,000 running watts from this generator which is perfect for complete home back-up power solutions or running a job site’s worth of tools and lights.

Outlet Selection

CAT has done a great job in understanding how their generator will be used and has integrated protective outlet covers to make sure that your outlets are always protected from dirt, debris, and moisture.

This specific CAT generator is going to come with 1 12V DC outlet, 4 20A household outlets, 2 30A 120V L5-30 outlets, 1 30A 120/240V L14-30 outlet, and 1 50A 120/240V L4-50 outlet.

This gives you the ability to plug in just about any appliance or tool you can think of into this generator.

Fuel Capacity & Run Time

The CAT FP12000E generator is going to feature a 13.2 gallon fuel tank to allow for 11.7 hours of runtime at 50% load. This makes it ideal for full day use on the job site or overnight use during a power outage.

Stand Out Features

This CAT generator is going to feature great standout features such as covered outlets, LED control panel lighting for easy nighttime viewing, and built in never-flat wheels with a collapsible handle.

IMHO: In My Humble Opinion
For the price being as competitive as it is, the CAT RP12000E is a great bang for your buck deal. Since it is built for mostly commercial use, the average homeowner could get a high powered generator built for the toughest conditions for the same price as a standard, non commercially built generator. I would highly suggest investing in any type of CAT product, especially this generator.

7. Northstar 15000

Northstar is a brand of generators that I have not previously reviewed, so when I saw the Northstar 15000, I was eager to see what they were all about.

After all, the price is in the higher range, so I wanted to see how it compared to some of the other generators on this list.


This NorthStar portable generator is going to offer about the same type of power levels at 15,000 starting watts and 13,500 running watts.

It features a Honda GX690 OHV engine which produces 22 horsepower.

The running watts is a little higher than most on this list which makes it great for those who need a little extra wattage throughout the runtime.

The Honda engine is a great sign as Honda is known quite well for their engines.

Outlet Selection

When it comes to outlet selection, this NorthStar generator really blows away the competition with 11 outlets to choose from.

While they are not covered with protective outlets, I am thoroughly impressed by these offerings.

The NorthStar generator’s control panel is packed with 8 120V household outlets, 1 120V twist lock, 1 120/240V twist lock, and a 120/240V 50A outlet.

The 8 household outlets are something I have never seen before, but wish I could see more of.

This allows you to plug in up to 8 different small appliances to be run at once.

Fuel Capacity & Run Time

This generator is going to be equipped with an 11 gallon fuel tank that allows for 8 hours of runtime at 50% load. This is a little less efficient than most of the generators on this list, but it still provides a full workday worth of power.

Stand Out Features

Some of the great features you can expect on this generator are an ultra-quiet muffler, premium $100 copper-wound generator head, vibration isolation mounts, and a variable timing digital CDI ignition.

IMHO: In My Humble Opinion
At nearly $1,000 more retail than many of the other similar generators, I am not completely sold on the extra cost. The outlet selection and 4 year warranty do make a great upsell, but for this type of money, I would have expected a little more features to take advantage of.

Check Price on Amazon

8. Dayton 6FYA4

Another lesser known brand, Dayton has made this list with its 6FYAA4 15kw generator.

This generator is the most expensive generator on this list, so let’s see if the price tag matches the power and features.


The Dayton 6FYA4 generator is going to feature a 688CC Honda engine with an electric start. This engine is going to put out 20 horsepower and allow for 12,000 running watts and 19,600 starting watts.

It is safe to say that this generator was built for commercial use as the fully tube cage and bare bones control panel aren’t exactly the prettiest things to look at from a residential use standpoint.

Outlet Selection

The outlet selection on the Dayton 6FYA4 generator is pretty standard for its class and there is an absence of protective covers which is a little disappointing if this generator is meant to be used commercially.

For this generator, you can expect 2 5-20R 120VAC Duplex GFCI outlets, 1 L5-30R 120VAC Locking outlet, 1 L14-30R 120/240VAC Locking outlet, and 1 14-50R 120/240VAC outlet.

Fuel Capacity & Run Time

This generator is going to feature a large 13.2 gallon fuel tank which will allow for an 8 hour run time at full load. This is one of the best full load run times I have seen on this list, so a full day use at full load is quite impressive.

Stand Out Features

This generator did not have any features that really stood out to me. At the price tag this generator sports, I really expected more features to be included.

IMHO: In My Humble Opinion
This generator is a textbook definition of a bare bones generator. At a price of over $6,000, this is probably going to be a generator reserved for those in the commercial industry with larger budgets. I would not suggest this generator for residential use as there are other budget-friendly options with more features.

Check Price on Amazon

Final Words

I hope that this review has made searching for a 15kw generator easier.

With investing a large amount of money into a generator of this size, it is important to know as much as you can before making a purchase.

If you really only need a small amount of power, see my list of the best portable generator, which will be more convenient.

As with any generator, you will want to make sure to completely read the manual to understand all of the features, specs, and maintenance schedules to keep you and others safe.

15kw generators carry a bigger responsibility than smaller standard generators, so ensure that you become quite familiar with operating your generator.

Are you currently using a portable generator? If so, what size, and what appliances are you running with it?

Please consider sharing this post with anyone you know who might be in the market for a 15kw generator!

How to Set Up a Home Generator

Severe weather costs the United States between $18 billion and $33 billion a year. And that number just goes up when there’s a major event: In 2008, when Hurricane Ike hit, weather-related outages cost the country between $40 billion and $75 billion per a 2012 White House report. Hurricane Sandy knocked out power for more than 8 million Americans. For those experiencing more regular power outages, generators are no longer just a convenience, but a necessity. Here is our handy guide:

First, Know Your Power.

If you haven’t thought about watts since grade school, know this: They measure power. One kilowatt is 1,000 watts. The higher the wattage of an appliance, the more electricity it consumes. The generator size you buy depends on the wattage of the devices that you want to keep running. So first, add up the wattage requirements of your essential devices. The average lightbulb is 100 watts. A coffeemaker uses about 1,000 watts. A refrigerator runs on about 1,000 as well. If you ration what you use during a storm (say, unplug the refrigerator for extended periods), then you can justify a smaller generator.

Which Generator Is Right for You?

Danny Lipford, host of nationally syndicated TV and radio home-improvement Home Generator shows, says the best brands are Generac, Briggs & Stratton and Kohler. Depending on what you’re powering, you’ll choose one of three sizes (costs are ballpark):

Small Portable: The smallest generators are gasoline-powered, pull-start models that put out between 1,000 and 2,000 watts and are handy for power tools and recreation. Newer “inverter” generators have appeared on the market within the past decade. Quieter, more efficient and lighter than conventional counterparts, they often cost about twice as much.
Price: $400”“$500.

Large Portable: A 7,500-watt gasoline-powered generator will be enough to keep the lights on and power most home appliances, with the exception of central air-conditioning and heat.
Price: $1,000”“$1,500.

Whole House: Starting at about 12,000 watts, these generators can generally keep a home running without missing a beat. You’ll be able to run lights, fans, TVs, refrigerators, computers, space heaters and pretty much anything else you plug into an outlet. In rural areas where water comes from a well, it can run the well pump, too. These are wired directly to your electrical system, powered by propane or natural gas and will require a professional electrician to install.
Price: $5,000”“$10,500 including installation for a 12,000-watt model, and up.

Safety First!

1. It’s really critical to take safety precautions when running a portable generator. First, never run generators inside a home, garage or enclosed space, or near open windows or any place that carbon monoxide could enter.

2. If you’re using an extension cord to bring power from a portable generator to your appliances, it needs to be rated for the amount of power coming through. And it should never be plugged into an outlet in a home. This can cause backfeeding, which means that power travels the opposite way through power lines and can injure or kill utility workers trying to restore power.

3. Wiring a generator directly into your home must be done by a licensed electrician.

The Battle of the Home Standby Generators: Generac vs. Kohler vs. Briggs & Stratton

Here is Everything You Need to Know About Generators and Sizing

When it comes to choosing a home standby generator, you have a ton of options. This type of permanently installed unit is designed to kick on automatically during an outage, and comes in various different brands and wattages— with their own special features.


We’re taking a look at three of the top brands of home generators, comparing similar models side-by-side to help you find a partial or full-home generator for your needs.


Let’s see how these three comparable Generac, Kohler and Briggs & Stratton standbys “stand-up” against one another.


Small-Sized Partial-House Standby Generators

A generator from anywhere to 7-11 kW can often power basic circuits in your home, such as your fridge, sump pump, garage door, etc. It’s a wattage that typically supports the “essentials” and is often ideal for small homes or partial home functionality during an outage.


Check out these three similar generators: Generac’s Guardian 11 kW, Kohler’s RESV 12 kW and Briggs & Stratton’s Fortress 12 kW generator, in this helpful chart:

Old Small


The Winner: Generac’s Guardian

  • Sound level. Although the other two generators offer higher wattage, they run significantly louder, at between 8 or 14 dBA noisier than the Guardian. Generac can thank its Quiet-Test™ low-speed mode for its superior noise levels.

  • Sleek tech. Unlike the Briggs & Stratton’s model, Generac’s Guardian and Kohler’s 20RESV models come with a multilingual LCD display, which allows you to monitor your battery status and track maintenance recommendations.

  • Remote monitoring. Though all three brands offer generous customer support, Generac’s generator comes with free remote monitor through Mobile Link™, which gives you access to your generator via your smartphone or tablet, on-the-go.

Generac Home Generator Fuel Consumption

When people are trying to decide on which Generac home generator would best serve their needs, one of the first thing they want to know are the fuel consumption rates for those back-up generators they are considering for purchase. The information that you supply to your Assurance Power Systems sales person will greatly assist them in providing you with the best home generator choices for your specific needs. Propane and natural gas generators are fast becoming the most popular generators for home and commercial use as they are considered the most efficient and environmentally friendly of available fuel choices.

Some key points to understand when researching propane and natural gas generator fuel usage, in addition to a particular generator’s fuel consumption rate, are the characteristics of the fuel that powers that engine. While older diesel and gas generators may have environmental and storage concerns, propane generators are considered clean burning and easily stored in various sized tanks suitable for the intended purpose of that generator.  Supply and delivery is as readily available as any other fuels used in generators.
Generac home generator fuel consumption rates will vary depending on the size and model of the generator and the load it is under.  For example, according to Generac a 22 kilowatt generator would burn approximately 2.1 gallons per hour at ½ load and 3.6 gph at full load, while a larger 38 kilowatt unit would burn 3 gallons per hour at ½ load and 5.4 gph at full load.

By knowing the Generac home generator fuel consumption rate, an Assurance Power Systems specialist can assist you in determining the size liquid propane tank that would hold the needed quantity for the estimated amount of running time you anticipate for you needs. In many areas natural gas lines and propane tanks are already installed, and your APS specialist can also determine the most effective and efficient ways to use any existing gas lines and storage tanks. Using our previously mentioned Generac Home Generator sizes, a 22 KW Generac generator would consume 5.9 cubic meters per hour of natural gas at ½ load and 9.7 cubic meters per hour at full load.

These are mere approximations as generator fuel consumption rates for different models, and by running at different loads may vary the fuel usage to some degree. It is also important to understand that in addition to the different loads that will affect fuel consumption caused by the number and size of appliances you are using, the effectiveness of home insulation may also factor into fuel consumption, as it directly affects the load placed on air conditioning.

The technicians at Assurance Power Systems are experts in determining the proper size generator for your needs and what type of fuel should power it.

5 Best Home Standby Generators You Can Buy In 2021

Kohler Generator vs Generac Generator vs Honeywell Generator – With the consequences of a hurricane and other catastrophes, many families are evaluating their disaster-preparedness plans.

One of the main things to plan for is your power supply… Kohler Generator vs Generac Generator vs Honeywell Generator.

A generator will help you in the event of a hurricane, tornado, power outage, and other long- and short term situations.

Generators are invaluable for countless other reasons as well. As blackouts are continually on the rise, in the United States especially, owning a generator is a smart idea.

In this post, we’ll tell you everything you need to know about the difference between Honeywell, Generac and Kohler generators.

You’ll learn what is important to consider for your situation and be able to make the choice between these popular models for yourself.

Best Generators At a Glance: Our Recommended Generator

  • Kohler Home Generator with Transfer Switch
  • Generac Home Standby Generator with Transfer Switch
  • Generac 7036 Guardian Air Cooled with Transfer Switch
  • Honeywell Air Cooled Generator

Kohler Generator vs Generac Generator vs Honeywell Generator

First, you need to decide if you want a standby generator or a portable generator.

There are several options as both brands offer both models.

Generac standby generator, Kohler standby generator, Honeywell standby generator and Generac portable generator or Kohler portable generator.

Kohler standby generator

The Kohler standby generator is one of the most reliable home generators in the market. The build is powerful, consistent and long-lasting when it comes to supplying back-up electricity at home.

Generac standby generator reviews

It is a permanently installed back up or standby generator that either runs on liquid propane or gas. The generator electrically protects your home, automatically, from blackouts, power surges, and/or outage.

Generac Generators Review

The Generac generators have developed an incredibly positive reputation very quickly.

Generac engine

Generac constructs their own, custom OHVI engines for their generators.

Because of this customized engine, Generac generators last for a long time, making them a wise investment for those who plan to use their generators for years, even in commercial applications.

Additionally, these generators can create up to 2 MW of power.

Their pressurized lubrication means that they’ll last for a lot longer than other engines, without needing as many repairs/replacement parts.

How Long Will a Generac Generator Last

Kohler Generator vs Generac Generator

Generac Generators Enclosure

In terms of the enclosure, Generac generators have either steel or aluminum options.

As you’re likely aware, these materials are inflammable. This makes them a wise choice if you need to put them closer to a noncombustible surface.

However, if you live near salt water, make sure you select the aluminum enclosure option — a steel one will rust.

Generac Generators options

When it comes to buying a generator, many shoppers are impressed by the wide variety of options Generac offers. You can even select the color of generator you want.

Generac offers ranges of 6 kilowatts to 50 kilowatts, so it’s easy to find the amount of power you’ll need to keep your home or office running in any circumstances.

You can also find options that are specific to the environment that you live in, and well within your budget.

Generac Generators – Sound of silence

When it comes to customer satisfaction, there’s much to love about Generac generators. If you don’t want the loud rumble of a generator, then you should certainly consider Generac.

This is because their generators are designed to be much quieter than other options on the market. They can even run a self-test that’s as close to silent as possible.

Additionally, these generators are made with what Generac refers to as “G-Flex” technology. This means the engine self-adjusts according to the amount of energy you need.

Since they’re not running on high all the time, they’ll be much quieter. Plus, they’ll save you fuel.

Generac Generators commitment to the environment

If you’re interested in off-the-grid living, chances are you have a lot of love and respect for our earth.

You likely want your environmental impact to be as low as possible, even when it comes to the type of generator you purchase. This is another reason why so many people love Generac’s products.

First, the brand has made a commitment to continually testing and developing technology that will allow for generator users to reduce their footprint.

Additionally, there are lots of fuel options that lessen your impact on the land around you. One of the most popular is called Bi-Fuel. This is a combination of natural gas and diesel fuel. Its goal is to make your generator run for longer, while also lowering its amount of carbon emissions.

So, if going green is important to you, Generac generators are a great option.

Generac generator cost

The average cost of a Generac generator is about $1,500 to$ 2,000 for home use.

However, it can go as high as $5,000 to $3,000 depending on the type, series, edition, power or features of the Generac generator chosen. An expensive generator that costs so much is more likely to be an industrial type of generator.

What Size Generator Do I Need

Kohler Generators

A competitor to Generac is Kohler generators. Kohler generators are another wonderful option when it comes to your power supply.

They’re one of the biggest names in the industry for a reason. Select the Correct Home Generator Size Calculator for what you want to power during an outage.

Kohler Generator Engine

When it comes to engine life, the two brands both have options that are designed to last for as long as possible. In fact, Kohler offers a 2,000 hour, or five-year, warranty on all of their standalone models.

However, what’s especially interesting about Kohler’s generators is that they are commercial-grade.

Kohler Generators automatically sense and switch on in the event of a power loss.

This means that, in the event of an outage, it will only be a few seconds before power is restored.

Unlike with a portable generator, this means you won’t have to brave going out into a dangerous storm just to switch on your generator.

If you’re concerned about safety, this is a huge plus.

Kohler generators know to automatically switch on because their standby generator models are installed permanently next to your home, and are always monitoring your power supply.

Additionally, Kohler engines are a bit sturdier than Generac engines. Therefore, if you live in a harsh environment, this is likely the option to go with.

Kohler Generator Enclosure

When it comes to enclosures, Kohler has more options than Generac does. You can choose between plastic, aluminum, and steel enclosures.

Unless otherwise specified, Kohler’s standard enclosure material is the plastic option.

Of course, since plastic can easily burn, you can’t place it as close to your home as you could a Generac generator (Of course, you could always choose another material.)

However, the plastic option is immune to corrosion. So, if you live in a place with plenty of salt in the air, this will likely be the better choice for you.

Kohler Generator’s history

Sometimes, no matter how good an offer from a new company sounds, you just feel more comfortable going with the brand that has a proven track record.

The same can certainly be said of generators.

Kohler has the resources to conduct serious quality testing, throughout both the design and the manufacturing process. Plus, they’ve been in business for nearly 100 years.

This means that their products have withstood the test of time. Additionally, it means that it’s much easier to get instant support when you need it.

If you’re having problems with your generator, you can easily get in touch with a representative of Kohler, to quickly get the problem solved.

Finally, the company’s size and influence mean that it has lots of local representatives in many different areas. This means you can meet with a specialist in person, should you ever want to. This kind of advice can be invaluable.

Honeywell Generator

Honeywell Standby Generator

How Much Does It Cost to Install a Backup Generator?

House Generator Cost by Type

Generators for home use come in two basic categories - standby and portable. Both come in a range of sizes, which can power some or all your home in a power failure, but they operate differently. Standby generators are hands-off, and portable generators require personal oversight and set up. They also have very different costs.

Cost of Portable and Standby House Generators

Cost of Portable and Standby House Generators

Type of GeneratorAverage Cost Range (Material Only)
Portable$500 - $2,000
Standby$2,000 - $20,000

Portable Generator Cost

Portable generators cost between $500 and $2,000 on average. Portable generators come in many sizes, from small units that power small areas to larger units that power most of a home. Portable generators run off of gasoline or diesel fluid. The generator and fuel are usually stored outside, often in a container made for that purpose. They are turned on, started manually, and connect to your home via an extension cord. You must monitor the generator’s fuel level and refill it if you need to use it for an extended time.

Whole House Generator Cost

A whole house or standby generator ranges from $2,000 to $20,000 on average. Standby generators are hardwired to your home. They sit on their own pad and are connected to a fuel source at all times. When the power from the grid is interrupted, the standby generator turns on automatically to power your home until the grid is reconnected. These generators use propane or natural gas and need a continuous supply. If you have propane tanks, your generator is connected directly to them. If you have natural gas, a line feeds your generator. These generators are larger and can often handle most or all your home’s load, depending on their size.

Compare quotes to get the best price on your backup generator installation

Backup Generator Cost by Size

Portable and standby generators come in several sizes. Portable generators are smaller than standby generators because they are often not designed to power the entire house. They can start under 2kW, but you need 5kW or more to power some of your home. Standby generators start at 7kW, but most homes need a 10kW to 12kW minimum, while homes with higher power needs may need larger generators.

Cost of 5kW - 6kW, 7kW - 12kW, 13kW - 16kW, 17kW - 21kW...Backup Generators

Cost of 5kW - 6kW, 7kW - 12kW, 13kW - 16kW, 17kW - 21kW...Backup Generators

Generator SizeAverage Cost Range
5kW - 6kW$600 - $2,000
7kW - 12kW$800 - $4,000
13kW - 16kW$3,500 - $5,000
17kW - 21kW$4,500 - $7,000
22kW - 25kW$6,000 - $10,000
30kW - 38kW$10,000 - $20,000

What Size Generator Do You Need?

Ultimately, the generator’s size you need is determined by your typical daily power consumption. The process includes a visit to your home by the installation team before you purchase it. During this visit, they determine your system type, whether you have a well pump, your hot water heater’s power source, light count, and what large home appliances you have. You can choose the smaller size if your home is between sizes, which may mean using one large appliance at a time. Or, you can size up to use all appliances and lights.

You can get a basic understanding of the size you need by taking a survey of appliances, HVAC systems, lights, and outlets you need during an outage. These should all be labeled with power ratings. 1,000 watts equals 1 kilowatt. Energy-efficient lights use 6 watts each, while a hair dryer uses 2kW alone. Determine the size you need by adding up the watts you need during an outage.

Home Generator Price by Power Source

If you have a standby generator, you likely want to power it with natural gas, propane, or another readily available fuel that you can store in large tanks. Portable generators can be fueled by gasoline or diesel fuel, but you must purchase and bring smaller amounts home when you need the generator. Some portable generators are not limited to one fuel option and have a switch button that you can press to change from one fuel source to another. 

If you want a portable generator without storing liquid fuel, you can use a solar generator. This works differently and charges batteries for later use.

Each generator has pros and cons to consider. For many, there is an overlap in costs for the generator. Fuel costs and availability are often the driving force behind your choice.

Price of Gasoline, Diesel, Propane, Solar and Natural Gas Generators

Price of Gasoline, Diesel, Propane, Solar and Natural Gas Generators

Fuel TypeGenerator TypeAverage Costs
GasolinePortable$500 - $2,000
DieselPortable$500 - $2,000
PropanePortable or Standby$500 - $20,000
SolarPortable$1,500 - $5,000
Natural GasStandby$2,000 - $20,000

Gasoline Generator Price

Gasoline-powered generators cost between $500 and $2,000. Gas-powered generators are portable, not to be confused with standby natural gas-powered generators. Gasoline generators require you to purchase gasoline at a gas station and to store it until needed. Each generator uses gasoline differently, depending on the size and runtime. You must have sufficient gasoline on hand for prolonged outages. You also need to periodically refill your generator. Gasoline should not be stored inside.

Diesel Generator Price

A diesel generator ranges from $500 to $2,000. Diesel generators are also portable versions. You must purchase and store the diesel fuel until needed. Not all gas stations sell diesel, so ensure you have a nearby source. Like all portable generators, the fuel it uses is determined by the size and runtime. Prolonged outages may need extra fuel and frequent refueling. Diesel fuel should not be stored inside.

Propane Generator Price

Propane generators average $500 to $20,000, depending on whether they are portable or standby. Portable propane generators require you to purchase and store the propane until needed. Standby propane generators are connected directly to your home’s propane tank supply. As long as you have a sufficient supply in your propane tanks, the standby generator continues to draw. Since most propane delivery services can make deliveries even in a power outage, you are unlikely to run out of fuel with this generator. Do not store propane inside.

Solar Generator Price

Solar generators cost between $1,500 and $5,000. Solar generators work differently than other types. They are portable generators that run on batteries, and the batteries come as part of the package with the panels. You charge the batteries using solar panels before you need them. They only charge fully on sunny days, so do not wait until a storm to charge them. Once the batteries are charged, you can save them until needed. They hold their charge indefinitely, although brands may differ in their charge life. Then, you hook up your portable generator to the batteries. You can go several days or weeks without grid power, depending on the weather and battery capacity. Each battery’s capacity and the length of time it will power your generator varies by the brand and use. The batteries are safer to store than liquid propane, gasoline, or diesel fuel. There are also no ongoing fuel costs after the initial purchase, while other portable generators require frequent fuel purchases.

Natural Gas Generator Price

Natural gas generators range from $2,000 to $20,000, depending on the size. These are standby generators. They hook up to your home’s natural gas supply. If you have natural gas for cooking, heating, fireplaces, or other appliances, you can easily split off a line for a natural gas generator. This is one of the easiest generators to maintain because you do not need to worry about the fuel supply. Even propane standby generators must be watched to ensure another delivery is not needed before the power returns. With a natural gas generator, the fuel supply is constant.

Home Generator Cost by Type of Start

Home generators can also be classified in how they start. You can have an automatic generator, which turns on when it senses a disruption in your home’s power supply, or a manual start, which means you must turn the generator on.

All automatic generators have a manual start option, but all manual generators remain manual.

Cost of Manual and Automatic Home Generators

Cost of Manual and Automatic Home Generators

Generator StartAverage Cost Ranges
Manual$500 - $2,000
Automatic$2,000 - $30,000

Generator Manual Start

Generators with a manual start only cost between $500 and $2,000. These are portable generators. They must be removed from their housing, connected to your home, and filled with fuel or connected to a battery to work. Some start by pushing a button, others have a pull cord. Some can be very physically demanding and difficult to start. If you are unsure if you can physically turn it on, opt for a push-button model or choose an automatic standby model.

Automatic Generator Cost

Automatic generators average $2,000 to $20,000, depending on the size. Automatic generators are standby generators. They are always “on.” They typically run for about 10 minutes once a week for maintenance. They are permanently hardwired into your home’s electrical system. When they sense a drop in power, they start providing power to your home. They stop providing power when they sense the power returning. All automatic generators have a manual override. This way, you can turn them off at night or when away from home and then turn them back on again when you need them.

I always recommend an automatic transfer switch so, even if you are not home during a power outage, your generator will turn on within ten seconds. When you think about the items in your refrigerator, freezer, or even an A/C unit in a desert home, any delay in turning on backup power can cause significant damage and loss.

Average Cost of Whole House Generators by Brand

You may have one or several brands of generators to choose from, depending on your area and available installers. Each brand has different costs, fuel types, sizes, and other considerations.

Cost of Briggs & Stratton, Kohler, Generac and Cummins Generators

Cost of Briggs & Stratton, Kohler, Generac and Cummins Generators

BrandAverage Costs (Material Only)
Briggs & Stratton$2,000 - $5,000
Kohler$2,000 - $6,000
Generac$2,000 - $30,000
Cummins$3,000 - $15,000

Briggs & Stratton Generator Cost

Briggs & Stratton generators cost between $2,000 and $5,000. This company also makes smaller portable generators, starting at $700. Their standby generators run off of propane or natural gas. They come in sizes up to 15kW, which is sufficient for most homes. Their smaller portable generators run off gasoline. These costs do not include transfer switches or other parts necessary for installation.

Kohler Home Generators Cost

Kohler generators average $2,000 to $6,000. Kohler is one of the first manufacturers of backup generators. Their plant was once a backup generator for large regions for nearly 2 decades, and they have some of the best-known generators in the country. Their sizing can be found in up to 15kW, which is sufficient for most homes. Their standby generators can run off of propane or natural gas.

Generac Home Generators Cost

Generac home generators range from $2,000 to $30,000, depending on the size. Generac is one of the most popular and frequently installed residential standby generators. They have an incredible line of generators that can power large commercial spaces and smaller residential ones. You can easily find a generator that can power even the largest home with the heaviest power needs. Their generators can run on propane or natural gas. Costs do not include transfer switches or other parts necessary for installation.

Cummins Generator Cost

The cost of a Cummins generator is between $3,000 and $15,000 on average. Cummins makes a very wide range of sizes for standby generators. Their generators can be powered by natural gas or propane. They pride themselves on producing generators of a higher quality and standard. Cummins generators are less likely to develop issues or suddenly stop working in the middle of an outage. Their costs do not include transfer switches or other parts necessary for installation.

Home Generator Installation Cost

Installation costs for a home generator start at around $5,000. Costs can go as high as $11,000 for very complex installations, but most people pay between $5,000 and $6,000.

The generator is seated on a small pad near the house, ideally situated close to your electrical panel. This pad can be concrete or filled with gravel. The generator is wired into your home’s panel, and a transfer switch is installed with it. The transfer switch senses interruptions in the power flow, which turns your system on and off.

A plumber is needed to connect your generator to your propane tanks or natural gas line. The process takes between 4 and 6 hours.

Home Generator Installation Cost Breakdown

Home Generator Installation Cost Breakdown

Installation AreaAverage Costs (Labor Only)
Bed Installation$500 - $1,000
Piping Installation$1,000 - $1,500
Wiring to House$1,000 - $2,000
Transfer Switch Installation$1,800 - $2,800

Whole House Generator Installation Cost

The total cost range for installing a whole house generator is between $10,000 and $20,000, including all parts and labor. The labor portion is roughly $5,000, while parts like the transfer switch cost roughly $1,000, and other materials and the generator make up the difference. This includes delivery, setting the generator, and hooking it to its fuel supply and electrical panel. Most of this project’s work is done outside. The transfer switch is installed indoors. In most cases, a section of drywall must be removed to install the transfer switch below your electrical panel.

Generator Transfer Switch Installation Cost

The transfer switch installation cost is roughly $2,700 to $3,700, including the transfer switch, electrical wiring, and labor. Labor makes up roughly $1,800 to $2,800, while the switch costs roughly $900. Installation is done indoors below your circuit breaker. The wall must be opened to install the transfer switch. You can have a box or door installed over it or tape and spackle over the drywall to conceal it. Mark the area and know that the wall must be opened again for future issues or maintenance.

Where Should a Whole House Generator Be Installed?

The exact location is likely determined by your home’s circuit panel location. The generator must be wired to the circuit panel and the transfer switch installed below it. The generator is usually located outside your home, a few feet away from the house, near the meter or circuit breaker. It may be moved a few feet in one direction or another to facilitate the fuel source hook up in some cases.

Hire a local pro to install a backup generator

How Much Does it Cost to Run a Whole House Generator?

The cost depends on several things, including the generator size, how much power you draw at a given time, the fuel cost and type, and how long you run the generator at a time. The cost to run a generator is lower when you do not run your HVAC system other than in the coldest or hottest months. Your costs to run are also higher if you use a lot of power at one time rather than conserving energy.

Estimates range from $0 to $500 per year in energy costs, depending on the amount you use the generator, the fuel cost, and runtime.

How Long Can a Generator Run Continuously?

The length of time a generator can run continuously varies. Standby generators are designed to continue running until the power is restored. This can mean running for days or weeks at a time. It can continue operating as long as there is a fuel source, and the generator is in good operating condition. Proper maintenance is required to ensure a standby generator can continue functioning in this capacity.

Portable generators run as long as they have fuel. Check the fuel supply frequently and top it up as needed. Most people with portable generators turn them off for stretches to conserve fuel or avoid running out in the middle of the night.

Some smaller generators have maximum run times. They vary by hours or days, so always check the owner’s manual for your model’s limitations.

Standby Generator Maintenance Costs

Standby generators are designed to run for a few minutes each week. During this time, they run self-diagnostics and can alert you to potential issues. Homeowners may have them serviced or pay for regular maintenance. Regular maintenance involves a service technician coming out on a scheduled basis.

Portable vs Standby Generators

Portable and standby generators are good options to keep lights and appliances running during a power outage. They work in different ways, however. A portable generator requires you to take it out of storage, put fuel in it, and plug it into your home. You need to manually start the generator, which can take some effort, depending on the model. You need to keep an eye on the fuel level and refill the generator as needed. This means keeping a supply of fuel on hand.

Standby generators are always “on.” They are hooked up to your home’s electrical supply and your natural gas line or propane tanks. They can sense a drop in power from the grid and automatically start to power your home. There is only about a 1 to 2-second delay between the grid going out and a standby generator starting.

Portable generators are often not large enough to power your entire home. You may need to choose what parts of your home you wish to power, such as the refrigerator and lights. Standby generators are usually sized to power your whole home at once, including HVAC, large appliances, and lights.

Enhancement and Improvement Costs

Generator Battery

A battery generator can power a few small lights or appliances. You can pair one with a portable generator to charge phones and power other small electronics, freeing the portable generator to power your large appliances or HVAC system. They cost around $50 to $100.

Wireless Monitor

If you have a standby generator, you can purchase a wireless monitor to get status updates when you are away. If you are concerned about a power outage while away and want to know if your generator is running, a wireless monitor can alert you. They cost between $200 and $400.

Smart Load Manager

If your generator is not sized to handle the entire load, you can use a smart load manager to help. Smart load managers prioritize which parts of the home are powered by the generator and let you switch as needed. For example, if your generator cannot handle multiple large appliances at once, you can direct it to power the washer and dryer first, then switch to the stove to cook meals. A smart load manager costs between $150 and $300.
