The SH Series of residential generators range from 1,000 to 3,000 watts of 120 volts AC, mounted on sturdy carts. Typically used for back up and emergency power for homes and small businesses during electric grid disruptions, the SH Series use quality components, and can power lights, appliances, refrigerators, televisions, and computers. Like our heavy duty SP series units, the power produced by the SF is quiet, clean, and renewable. The models in the SH series can easily be stored in a garage and set up is a breeze.
