THE PREMIUM STANDBY GENERATOR
Premium features are standard for the ultimate standby generator. Thanks to the low-speed engine, it’s so quiet you’ll forget you own a generator until you need it. Ideal for large residential and small to medium commercial applications.
Low speed, automotive style liquid-cooled engine runs at only 1800 rpm during a power outage for a substantially quieter generator, greater fuel efficiency, and longer engine and alternator life.

Super quiet, super efficient, patented Quiet-Test™ mode for a weekly test mode that’s quieter than other brands, consumes less fuel and helps make your Generac generator the most environmentally friendly on the market.
Standard aluminum, all-weather enclosure provides the ultimate protection from the elements. Aluminum’s natural corrosion resistance prolongs the life of your generator and  is recommended for salt-air, coastal locations.

QUIETSOURCE SERIES 22kW
