A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns - whether that's two hours or two weeks.
Perhaps it's a storm. Maybe it's an equipment failure. In any case, the electricity you depend on is suddenly gone.
Within seconds, your generator prepares to restore your home's power.
Within a few seconds, it is up to speed and generating electricity.
The automatic transfer switch sends generator power to your home. And it will continue until utility power returns.
