With Generac's Guardian Series, you need never invest in a larger backup power system than you need. From essential circuit coverage to backing up your entire home, there is a Guardian Series home backup generator that fits the bill.
What Makes the Guardian Series So Popular?
Generac's Guardian Series offers benefits that few competitors can match. Installation flexibility. Sophisticated yet intuitive controls. Quiet operation. All backed by 24/7/365 customer support at our corporate headquarters, and a nationwide dealer network more than 5000 strong.
Your Guardian Series generator might have to get you through days—or weeks—without utility power. Its OHVI engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
Thanks to Quiet-Test, your Guardian Series home backup generator runs its weekly self-test at a lower RPM.
Available on 16 - 22kW
Mobile Link is the cellular remote monitoring system from Generac that lets you check on your generator’s status even when you are away using your computer, tablet or smartphone.
Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.
The next generation of intuitive controllers features a multilingual, two-line LCD text display with color-coded, backlit buttons.
Available on 8-22kW only.
As the leader in the standby generator market, Generac continues to deliver innovation and value. Our new Guardian Series 22kW backup generator, the industry’s largest air-cooled generator available, provides home and business owners with the best value per kilowatt available in the market today. Until now, this amount of power was only available in more expensive commercial liquid-cooled generators.
