How Generators Work

Learn How the Automatic Home Stand-by Generator System Works!

Generac home standby generators provide peace-of-mind with an automatic source of energy as soon as a power outage is detected. Permanently installed, the generator starts automatically – whether you’re home or away. Running off your natural gas or liquid propane supply, Generac generators provide you and your family with the security of having your very own Power Plant directly installed to your home! 

The system maintains consistent voltage to eliminate voltage spikes and allows the operation of sensitive electronic equipment. 
Imagine relief that comes with never having to worry about your home security system without power, whether you’re at home or not?
How about not returning home to a refrigerator full of spoiled food or a flooded basement?

Those are just some of the many benefits you can expect with an automatic home standby generator!

Generac Air-Cooled Standby Generators are a complete line of emergency automatic standby generators for home or businesses that can be installed during new construction or retrofitted into existing structures. 

Residential emergency home standby generators are permanently installed outside (similar to an air-conditioning unit) and supply electrical power to all pre-selected lights and appliances, and are powered by either natural gas or LP gas. Models range from 7,000 to 40,000 watts. They work with a matched automatic transfer switch that responds within seconds when utility power shuts down, even when no one is home!
