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 purchased a new generator in January 2012. Prior to the purchase, Allan came to our home and discussed in depth our needs then recommended a generator. Lead time on the order was about 6 weeks, but through that time they kept me informed as they received messages from Generac. The generator was delivered on the day they had told me and installed without any problems at all even though the installation required visits from both electricians and the gas company. Everyone involved was prompt, polite and we were very pleased with the entire process. Best of all, the final price was exactly as originally quoted and with no add-on unpleasant surprises even though the installation was more difficult than originally anticipated. We were pleased with the entire process and are happy to recommend Allan Dearth and Sons.Yes, I recommend this dealer. Tom from Highlands, NC
