Meet the Generac 22kW Next Generation Generator

The Generac 7260 (22kW) standby generator is an excellent option for homeowners who want serious whole-home backup power, especially for larger homes or households with heavier electrical demands (multiple refrigerators, well pumps, sump pumps, electric cooking, larger HVAC loads, etc.). It runs on natural gas or propane, turns on automatically when the utility power drops, and delivers clean, steady power that’s safe for modern electronics. It also helps keep itself “battle-ready” with automatic weekly self-tests, so you’re not guessing when the next storm hits.

A big standout is the built-in connectivity—with cellular + Wi-Fi + Bluetooth and Mobile Link™, you can monitor generator status, receive alerts, and stay in the know right from your phone whether you’re home, at work, or traveling.

Early this morning I experienced our first extended loss of power due to a large tree falling in the area. After a few seconds in the dark and some supernatural sounds, our generator powered right up. Nine hours later power is still out but our generator is going strong. Definitely one of the best purchases we've made!
