Lowest Cost Per Kilowatt
Homeowners can invest in a home standby air-cooled generator size that used to only be available in much more expensive, liquid-cooled models, giving them the lowest cost per kilowatt available.
Generac OHVI® Engine
Your Centurion Series generator might have to get you through days—or weeks—without utility power. Generac’s OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
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.
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.
Certified for 18" Installation to the Home
Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.
When combined with a pre-wired transfer switch or Smart Switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Centurion Series 22 kW generator is easy to install.
Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Centurion Series 22 kW generator can operate on natural gas pressures of only 3.5” of water column.
All-Weather Aluminum Enclosure
Our durable powder-coat finish helps make the sturdy, all-weather aluminum enclosure corrosion resistant, making it ideal for coastal, salt-air climates. It’s also able to withstand 150 mph winds.
Tool-less Fuel Conversion
Switch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.
Thanks to Quiet-Test, your Centurion Series home standby generator runs its weekly self-test at a lower RPM for only five minutes. Choose your schedule - weekly, bi-weekly or monthly.
Mobile Link™ Compatible
Take advantage of Generac’s Mobile Link cellular remote monitoring system and check on your generator’s status using your computer, tablet or smartphone, even when you are away. Sold separately.
Non-cellular remote monitoring options are also available for generator monitoring from inside the home.
