Generac is always innovating to meet customer needs. For instance, we just launched a 22 kW Guardian Series home standby generator. Check out our “What’s New” page to learn about it and the other new products we have available.
Generac's most popular home backup generators, the Guardian® Series kicks in within seconds of determining power loss—automatically—and runs for as long as necessary until utility power returns.
“I’d be more than happy to buy it again, it is one of the best investments I have ever made in this house.” — David Panzerella
Why use a portable generator when you can invest in Generac's CorePower™ fully automatic home backup power solution to back up your essential circuits?
“I don’t have to worry. When the electric goes off the generator kicks in and in a minute everything goes back on and starts working. I can rely on it (my Generac Generator) 150%.” — Dorothy McCann
The Centurion® Series is fully automatic and can protect your entire home or just the most essential items.
“To me, this generator has paid for itself several times. My family is going to be safe and secure in my house because of this generator. That gives you that feeling of security that is priceless.” — Greg Baeppler
The QuietSource® Series is the strong, silent type. Its premium features make it the ideal solution for larger residential backup power.
“I pretty much tell everybody ‘get a generator’. I had my (Generac) generator installed in January, 2012. It’s a whole house system so everything is connected, I don’t have to worry about anything. It’s very reassuring.” — Eve Hershkowitz
EcoGen™ is the only automatic backup generator engineered specifically for off-grid use with an alternative energy system, like wind or solar power.
“In 10 seconds, the lights come on, everything powers up, and you just go right back to working on the computer or watching a show or a movie. I don’t have to do anything…its great!” — John Borell
Don’t have easy access to natural gas or liquid propane fuel? No problem. The pre-packaged Protector™ Series backup generators run on diesel fuel, and are more cost-effective than many competitive diesel-fueled generators.
“When the power first went off, within the first few minutes we got calls from our neighbors asking us how come we still have power?” — Gerald Grupp
Subject to credit approval. Minimum monthly payments required. Available in the U.S. only. See dealer for details.
