How Does a Home Backup Generator Work?
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.
1 Utility Power Is Lost
Perhaps it's a storm. Maybe it's an equipment failure. In any case, the electricity you depend on is suddenly gone.
2 Your Generac Generator Senses A Problem
Within seconds, your generator prepares to restore your home's power.
3 The Generator Turns On Automatically - Whether You’re Home Or Away
Within a few seconds, it is up to speed and generating electricity.
4 Your Electricity Is Restored
The automatic transfer switch sends generator power to your home. And it will continue until utility power returns.
