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.
