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 had trouble with my Generator after a bad storm. It worked for awhile, then started acting erratic, on and off. The next day I contacted 3 other dealers that were in Shreveport, La. They all said they did not work on units that they did not sell and install. I installed it myself a year earlier, and it had been working fine. Thanks allot huh? Well, after contacting this dealer the same day, he knew I was really between a rock and a hard place as I lived in an area where the Ele. goes out very often. He sent his best tech out that very day, even though he had allot of service calls to make just north of him where a bad storm had gone thru that same night and left the whole town with power lines down and people without power, yet he found time to get to my problem. Oh by the way, one Dealer told me it would be 6 to 8 weeks before they could get to me. I think just another way of telling me, "If they didn't sell and install it, they weren't going to come out!" This is the first time I have EVER given anyone or anything a review, and can truthfully say that This Dealer is as good as gold. The best service, very professional, very nice, neat, friendly and knowledgeable service technician. Almost forgot, he drove over 45 mi. to my house, that's over 90 mi. round trip. You can't beat that, he's got my business from now on. Thanks Allot Guys... Larry - Gloster State, Louisiana
