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.

My 25 kw Generac generator was failing to automatically initiate operation. When I called my provider they sent Frischhertz Electric Services. Two service men arrived exactly as scheduled. Thereafter a third party, a supervisor, arrived. They quickly determined a defective controller was the issue. They had the part in their extensive inventory and could get it from their inventory immediately, No wairing to order a part. They fixed the problem, educated me on many nuances of the generator, and answered every question with a smile. They could not have been more professional, polite, and friendly. If only all service was like this. Wayne New Orleans, Louisiana
