24 KW Generac Guardian: Best Backup Generator For Your Home?

Is the 24 Kilowatt Guardian Right for You?

A whole home generator can be an important addition to your home, providing backup power in case of an outage. If you’re considering a 24kw Generac (7209 Wi-Fi enabled) whole home generator, here are some things to consider. Generac is a well-known and trusted brand, and their whole home generators are designed for reliability and ease of use. 


However, they are also more expensive than some other brands. Make sure you factor in the cost of installation and any required permits when budgeting for your whole home generator. And be sure to consult with a qualified electrician to ensure that your installation is done safely and properly.

Generators are a great asset to have for your home. They can provide backup power in the event of a power outage, and they can also come in handy when you need to power tools or equipment while you’re working on a project. If you’re looking for a generator for your home, the 24kw Generac (Model 7210) whole home generator may be just what you need. 

They designed this generator to provide backup power for your entire home, and it comes with several features that make it an excellent choice for homeowners. Keep reading to learn more about the 24kw Generac whole home generator and find out if it’s the right fit for your needs.

Will a 24kW generator run a whole house?

Installing a generator is a great way to ensure your home has the power it needs, even in the event of a power outage. However, it’s important to choose the right sized generator for your homes needs. A 24 kilowatt generator will be able to provide power for most homes, but if you have a larger home or one with particularly high energy needs, you might need a higher-powered generator. 


Generator installation is a popular option for those looking for an emergency power source. Generator size is an important consideration. An average American home needs around 18 to 30+ kilowatts of power for its basic electrical needs. In order to ensure that your home has enough electricity when the grid goes down, you’ll want at least a 22 kW generator. Generator installation can be a complex process, so it’s important to consult with an expert to ensure that your generator is properly sized and installed. With the right generator in place, you can rest assured that your home will have the power it needs when the next storm hits.

Professional electrical contractors typically handle generator installation, so be sure to get quotes from a few different companies before making your decision. With the right generator, you’ll be prepared for anything.

What is the difference between a 22KW and 24kW Generac generator?

While it is true that the Generac 22KW and 24KW use the exact same engine, the added power output of the 24KW comes from having a larger generator assembly. This means that, because the 24KW unit outputs more power, in theory the engine should not have to work as hard as one in a 22KW unit to produce the same amount of power. However, both generators are equally reliable and provide the same amount of power. So, if you’re looking for a powerful generator, either ‌will do the trick.


Our electrical contractor often gets asked about what size generator a homeowner needs to power their home in the event of a power failure. For larger homes, they recommend a generator in the 24-30kW range. This will replace 75% of the 200 amps coming into your electrical panel. 

However, for homeowners wanting a good whole-house standby, a 22kW or 24 kilowatt is a perfect choice to reap all the benefits of a whole-house generator. So, if you’re looking for a generator that can power your entire house, a 22kW or the 24 KW Guardian generator is a great option.

Models of 24kw Generac Generators

  • 24kW Guardian Series Home Generator – 7210 comes with ATS (automatic transfer switch)

  • 24kW Guardian Series Home Generator – 7209

Homeowners want to know which brand or model is the best, how much power they need, and what features are important. When it comes to backup generators, our recommendation is always the Generac Guardian Series. The 7209 and 7210 models are the largest air cooled generators on the market, yet they take up less room than other brands at similar kilowatt output. And if you go with the 7210 model, you’ll also get Generac’s PWRview Automatic Transfer Switch

This switch automatically manages the transition between utility and generator power, making sure you never have to worry about losing power during a blackout. Plus, it gives you the ability to monitor your energy usage and make adjustments accordingly. With all these features, it’s no wonder the Generac Guardian Series is my top choice for home backup generators.

How much propane does a 24 kilowatt Generac generator use per hour?

Generac’s Guardian Series generators provide homeowners with a reliable source of backup power in the event of an outage. Generac’s generators are available in a variety of sizes and fuel types, including liquid propane. If you opt for a Generac Guardian that uses liquid propane as its fuel source, you’ll be able to take advantage of considerable run times.

Most standard liquid propane tanks contain 250 to 1,000 gallons of propane, and a typical Generac Guardian 24 KW will burn through 2 to 3 gallons of propane per hour. As a result, you can expect your Generac Guardian to keep your home powered for many hours in the event of an outage.

How much natural gas does a 24kW generator use?

Generac’s Guardian 24 KW standby generator is one of the most popular options on the market, and for good reason. It’s a reliable unit that produces enough power to keep most homes running during a power outage. However, it’s also relatively fuel-efficient, using just 203 cubic feet of natural gas per hour at full load.

That’s 7 percent less than the 22 KW model and 14 percent more than the 20 KW model. So if you’re looking for a generator that’s powerful and efficient, the Generac Guardian 24 KW is a great option to consider.

Generac generators cost $3,000 to $7,000 for a 7 to 24 kW whole-house unit. Having a licensed electrician install it runs about $3,500 to $6,000 for installation. The cost involves permits, running gas lines and installation of the home generator units on a concrete pad.
