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.
OmniMetrix Remote Monitoring
We are now offering remote monitoring of generators that allows us to see the status of your unit 24 hours a day, seven days a week, every day of the year. If there’s a problem, the remote will alert us so we can be proactive, instead of waiting for you to call us.
When combined with a 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 20 kW generator is easy to install.
24/7/365 Customer Support
Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center—right here in Wisconsin—provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions.
Rated for Operation in Areas with Low Natural Gas Pressure
In areas with low natural gas pressure, the Centurion Series 20 kW generator can operate on natural gas pressures of only 3.5” of water column.
