This Briggs & Stratton 12kW 40689 generator is an emergency backup generator that keeps the family safe indoors during any power failure. It features a built-in front-facing exhaust for flexible placement options during installation. Extreme weather events can disrupt grid power supply for several hours or days.

With only 5% total harmonic distortion, the unit is safe for use with sensitive electronics such as computers, laptops, cell phones, and tablets.

The ATS needs only 2-6 seconds to start the generator and manages the power supplied to all your home circuits. This Power Protect Series generator can power a 5-ton air conditioner along with other essentials. It provides the comfort of generator power without the inconvenience of manual operation. The load management system ensures the generator never overloads and shuts down. The Low Idle Mode allows you to run weekly tests at a low RPM for fuel saving. You can program automatic exercise cycles to ensure the unit is ready for the next blackout.
