Generac Generators

Generac Generator Power
How Does It Work?

Your Generac generator is installed right outside your house, usually near the air conditioner. A disconnect panel is also mounted according to electrical code. The Automatic Transfer Switch (ATS) is mounted next to your existing electrical panel. The ATS is always actively monitoring your power status. If your power fails, it signals the generator to start. Within 90 seconds, your generator is up to speed, and your ATS switches over to Generator Power. To prevent injury, the ATS automatically prevents back feed into the electrical grid that has failed.

Generator Power - How Does It Works

When power has been returned, the ATS senses that stability in power has been restored, and seamlessly switches back to your regular electric service. Your generator will then begin warm-down, and shut off. It will remain in active monitoring status until the next time your regular electrical service fails.

Generac generators also run a weekly maintenance cycle at a time you specify. Your investment will keep itself in shape so it will be ready when you need it most. What about oil, fuel, and batteries? Your generator is just as easy, if not easier to maintain than your family car. The generator has front and side panels that come right off with a key, and everything you need to access is made easily available to you. The generator runs off of your natural gas line or propane tank, so you won’t have to worry about refueling. The battery automatically charges itself whenever the generator is running, including during maintenance cycles. The only thing you have to worry about is changing the oil, and that’s more simple and more easily accessible than most vehicles.
