Guardian Series Features

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.

Generac OHVI® Engine

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.

Quiet-Test™

Thanks to Quiet-Test, your Guardian Series home backup generator runs its weekly self-test at a lower RPM.

Available on 17 & 20kW only.

Mobile Link™ Remote Monitoring

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.

Sold separately.

True Power™ Technology

Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.

Evolution™ Controller

The next generation of intuitive controllers features a multilingual, two-line LCD text display with color-coded, backlit buttons.
