best generac home generator


As someone who has experienced multiple power outages in my area, I know the importance of having a reliable home generator. Choosing the right brand and model is crucial, as it can make a difference in restoring electricity to your home during an emergency. In this review, I’ll be discussing Generac, one of the top brands in the home generator market.


Generac is a company that has been in the generator industry since 1959. Their mission is to provide reliable and affordable power solutions for both residential and commercial use. Generac offers a wide range of home generators that differ in size, power output, and fuel type to fit any household’s needs.

Factors to Consider

When choosing a Generac home generator, there are a few key factors to consider. The first factor is power output. It’s important to choose a generator that can handle the power needs of your home. The second factor is fuel type. Generac offers generators that run on natural gas, liquid propane, and diesel, so choose the fuel type that is most accessible and affordable for you. The third factor is portability, which may be important if you’re looking for a generator that you can use for outdoor events. The fourth factor is noise level, as some generators can be quite loud. Lastly, durability and reliability are important considerations to make sure that your generator can withstand the test of time and be ready when you need it most.

Product Reviews

Based on the factors above, I’ve chosen to review Generac’s top home generators, including the Generac Guardian series, Generac Synergy, and Generac GP series.

Generac Guardian series

The Generac Guardian series is a standby generator that can be powered by either natural gas or liquid propane. It comes in a variety of sizes, from 9kW to 22kW, to fit any home’s power needs. This generator is durable and reliable, designed to provide power during any weather conditions. One downside is that it can be quite loud, but its power output makes it a reliable choice for households with high energy needs.

Generac Synergy

The Generac Synergy is a more energy-efficient choice for those looking to save on fuel costs. It has an automatic system that adjusts the power output based on household usage, meaning it only uses the necessary amount of fuel needed to keep the lights on. Its noise level is significantly lower than other generators, making it a great option for those who live in noise-restricted communities. One downside is that it is more expensive than other options due to its energy-saving technology.

Generac GP series

The Generac GP series is a portable generator, perfect for outdoor events and emergencies. It runs on either gasoline or propane and has a power output ranging from 1,800 to 10,000 watts. Its portability and multiple fuel options make it a versatile choice for any occasion. However, its noise level can be quite loud, and it may not be powerful enough for high-energy households.


While all three Generac home generators are reliable options, each one differs in power output, fuel type, portability, and noise level. The Generac Guardian series is great for high-energy households but can be loud. The Generac Synergy is more energy-efficient but is also the most expensive option. The Generac GP series is portable but may not be powerful enough for larger households. It’s important to choose the generator that fits your household’s specific needs.


Investing in a reliable home generator is crucial for any household, especially during power outages or emergencies. Generac offers a wide range of home generators that differ in size, fuel type, portability, and noise level. When choosing a generator, consider your household’s energy needs and the importance of durability and reliability. I hope this review has provided valuable insights for those looking to purchase a Generac home generator.
