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.

My wife and I have been thinking about a standby generator for about 3 or 4 years now and with our last power outage we thought it was about time! I called 911 generators and talked to a very nice lady who took all my information and told me the sales person would be in contact with me. Less then 10 minutes later their generator sales person called me and we talked about what our needs were. He had no problems answering any and all my questions over the phone, and then we set up a time for him to come out and do a site visit. He had no problem coming out after regular business hours since my wife wanted to be there as well. He talked about the best placement of the generator, what size fit our needs, and what was involved with the install. He took pictures, measurements and did a sketch of my property. He left some light reading material on Generac and told me he would have a quote to me the next day. He delivered as promised and the price was right !! The Install crew was very neat and professional. They did not mind that I kept peeking my head in (Being a bored retired guy), and they answered all the questions I had during the install. When they were finished, my yard and my basement looked as though I had cleaned it myself! One of the installers took his time while showing my the operation of the generator, and all the in's and out's once they were finished. We are very happy with our Generac Generator, and 911 Generators ! Thank you Very Much! Liverpool, NY
