How a Generac Home Backup Generator Works

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.
