Generac Residential Standby Generators

Generac’s Guardian Series generators provide the automatic backup power you need to protect your home and family during a power outage. Connected to your existing LP or natural gas fuel supply, it kicks in within seconds of sensing power loss— automatically—and runs for as long as necessary until utility power returns. Choose from Generac’s industry leading lineup to power just the essentials or Generac’s 22 kW, the largest air-cooled generator in the market for whole-house coverage.
