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 24 Kilo-Watt, the largest air-cooled generator in the market, for whole-house coverage.
