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.

Tim Groh the owner of Boston Standby installed my generator just about one year ago today. I had asked for estimates from 2 other firms that install generators. Tim was the only person who came to the house went over every detail of the installation, performed all the pre-estimate inspection details and took careful notes. He also made excellent suggestions as to the circuits I should have and the size generator I would need. His estimate was detailed and was the most competitive of the 3 estimates. In addition his attention to detail and his professionalism made my wife and I comfortable. He set a date for installation and did an outstanding job. Installation was done on time. When finished there was not even a scrap of anything left that needed to be picked up. I have since recommended Tim Groh and Boston Standby to friends. I know of a friend who had an installation done by him and is extremely pleased. He since has done the necessary oil change and installed the replacement transfer switch. I would point out one other thing. I had a friend who is an electrician look at the whole situation before installation and he had a list of what he felt would be necessary connections, etc., etc. It was a long list. When Tim was finished with installation he had done every one of these suggestions without ever having seen the list. Al Whalen / Marshfield Ma.
