Utility power is lost.
Maybe it’s a storm. Maybe a grid failure. Maybe one of those cyberterrorists finally broke through. Whatever the cause, the power is out and you need a solution.

Your generator turns on. Automatically.
Within seconds, your Generac generator senses the problem, turns on, and your house is fully powered–whether you’re home or not. And it keeps the power on, whether the outage lasts hours or weeks.

Your generator turns off. Automatically.
When your Generac generator senses that utility power is restored, it shuts itself off and returns to standby mode waiting to answer the call the next time you lose power.
