Generac Guardian Series 22kW Air Cooled Home Standby Generator with Wi-Fi and 200 Amp Transfer Switch

Generac Guardian Series 22kW Air-Cooled Home Standby Generator with Wi-Fi & 200 Amp Transfer Switch

Generac’s Guardian Series is the most widely installed home standby generator brand in North America — and this 22kW model is the flagship air-cooled unit. It fires up automatically within seconds of a power failure, connects to Wi-Fi for remote monitoring from anywhere, and ships with a whole-home 200 Amp transfer switch. It’s the most complete automatic backup solution available for residential use, period.

This is the standard answer for homeowners with larger properties, anyone with critical medical equipment in the home, work-from-home professionals who can’t afford downtime, and anyone who simply wants permanent, automatic, whole-home protection. Professional installation is required — this is a permanent fixture, not a portable unit you wheel out of the garage. Once it’s in, Generac’s Mobile Link Wi-Fi system sends alerts and live status updates straight to your phone, so you always know your home is protected.
