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.

In October of 2012, I decided that I wanted to have a standby generator installed at my home to provide full house "backup" power should I lose commercial power for a period of time. After a period of research, I decided on Generac. This was followed by seeking and obtaining bids for the purchase and installation of the whole system. Mr. Brian Stuller was among several bidders. All the bids received were in a close competitive range. When he came to present his approach to the installation, how the work would be performed, time frame of the installation and the competitive price quoted, he did an excellent job of explaining both the inside and outside work to be done. Therefore, my choice of Mr. Stuller was an easy one. All of the work was performed in a very professional manner. His decision to build a substantial concrete base for the generator was not matched by other bidders whose base would be of earth and gravel with a pad. His clean-up after installation was accomplished with care, indicating his recognition that this was a home and not a building site. I was very satisfied with Mr. Stuller's work from start to finish. I also am confident that he would make himself and/or his staff quickly available should I encounter any problem with the Generac in a time of real need. To date, I have not had a power outage. The system has automatically powered on each week as planned, which provides me an additional level of confidence that the system will perform as needed when commercial power is lost. I would express my confidence to others in Mr. Stuller's ability to do a fine job in an installation such as mine. James S. Simpson of Flat Rock, NC
