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.

"There is no hesitation in recommending Express Electrical who installed an emergency home generator for us. First, the written installation proposal was accurate, with above-board pricing and breakdown, and there were no surprise costs. Appointment dates and hours were met for the work on a timely basis. Since, upon completion of the installation, there exists an on-going relationship for maintenance, and possible emergency equipment failure, Express Electrical stands by their work beyond the generator warranty, and over a two year period after installation. We feel confident in their professional abilities, and that they'll be there if and when needed. Finally, an answer to power outages, and that's Express Electrical!" - Warren of Lower Merion Township, PA. Warren S. Lower Merion Township, PA. 19072
