Generac Power Systems, Inc. manufactures a complete line of emergency automatic standby generators for home or business 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), supply electrical power to all pre-selected lights and appliances, and are powered by either natural gas or LPG. 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!

In addition, Generac has introduced a feature packed Commercial Product Line that will revolutionize the generator industry. Ranging from 20 kW to 150 kW, these gensets provide value without sacrificing quality and cover the needs of most any larger residence, business or light commercial application. Single phase and three phase models available.

Generac is truly a vertically integrated manufacturer. From the core of the engine to the controls, we design and build our complete product. This is precisely why we stand so strongly behind it with one of the best warranties in the industry. With intensive control over our engineering through manufacturing, we're able to ensure that our products are quiet, powerful and reliable.
