Generac is the world's leading manufacturer of home standby generators and their engines are proudly engineered and built in the USA.

Generac was the first manufacturer to utilize an engine designed specifically for the performance requirements of air-cooled generators that operate at 3,600 rpm. The Generac backup generator for home uses an Overhead Valve Industrial (OHVI) engine. A fully pressurized lubrication system keeps critical bearings and other parts immersed in oil at all angles of operation. Low oil shutdown prevents engine damage, and the dual-element air filter extends service intervals while protecting the engine from dirt.

Generac Automatic Transfer Switches (ATS) are designed with state-of-the-art features. They can manage power for the whole house or a few essential circuits.

Briggs & Stratton Corporation pioneered the use of aluminum in gasoline engine design.

As a leading designer and manufacturer of standby generator systems, they and have garnered the trust of professionals across the globe and offer world-class support with thousands of dealers.
