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.

Dave Dawson of Smart Homes of Virginia was highly recommended to us by a trusted neighbor who used him to install a 27 KW generator and all the appurtenances. We met with him for what we thought would be a first estimate, but we were so impressed with his expertise and professionalism we looked no further. Dave loves what he does, and it shows. The day of installation the supporting crew were all highly skilled professionals, including master electricians. We are now in the sixth day of a devastating post storm power outage in the greater Central Virginia area, which is the very first 'call to duty' of our 20 KW Generac generator. It has been humming like a baby, working flawlessly. THANK YOU, DAVE! 5 of 5 stars. Deb585 / Earlysville, Virginia
