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 husband died suddenly in September, 2013. When the fog began to clear, as a wheelchair bound woman living alone, the first major decision I made was to e-mail manny@mtcomputers.com. Manny phoned me back within 20 minutes making an appointment to come to my home within two days. I'd done my homework tentatively choosing Generac. The real difference to me was Manny's service. He did it all, from installing the pad to walking me through the test drive. I know that he will be there when I need him. Manny was always where he said he'd be when he said he'd be there. He saw to it that those whom he contacted were aware of my circumstances and took care of business in a timely manner. I spoke to another customer of his who shares my observations. This has been a 100% positive experience. Manny represents your good product very well. Sincerely, Ann Lazarek Ann Lazarek, Pawcatuck, CT
