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.

I bought my Generac Generator about two and a half years ago. We have outages just about every time the wind kicks up. Some of the outages last only an hour and often they last hours. This fall we had Hurricane Irene that took our our power for four days. We had hot water for the kids baths, we had a stove to cook dinner. I remember when Gloria hit the area in 1995 and we struggled with the lack of power for about a week. I am thankful for my generator, it ran flawlessly everytime we needed it. It also provides me peace of mind that my family is protected when I am not around to take care of them. Dave Hall - Westhampton Beach, NY
