Generac Standby and Commercial Generators and Generac Products.

Generac Power Systems, Inc. manufactures a complete line of emergency automatic home standby generators that can be installed during new construction or retrofitted into existing residences and businesses. 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 watts to whatever your needs are. Single and three phase available. They work with a matched automatic transfer switch that responds within seconds when utility power shuts down, even when no one is home!

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.

How Does the System Work?

The completely automatic Guardian transfer switch monitors incoming voltage from the utility line - around the clock.

When utility power is interrupted, the automatic transfer switch immediately senses the problem and signals the generator to start.

The automatic transfer switch then safely closes off the utility line and simultaneously opens a new power line from the generator.

Within seconds, your Guardian generator system begins supplying electricity to the critical emergency circuits of your home or business. The transfer switch continues to monitor the utility line conditions.

When the automatic transfer switch senses the utility line voltage has returned at a steady state, it re-transfers the electrical load back to the utility line and resumes monitoring for subsequent utility loss. The generator will continue to run for an engine cool-down period of several minutes while the entire system stands ready for the next power outage.
