Yes,and it starts automatically after 6 seconds of lost power, then automatically switches back to regular power seamlessly. It does a maintenance exercise every other Wednesday at noon for 12 minutes. Having it also adds value to the house as well. My brother, who lives in Tampa, has a Briggs and Stratton with a 100 gallon propane tank. Kohler also makes one as well. The nice thing about propane, is should something happen to the natural supply, you still have power. A 500 gallon propane tank will run a typical home 24/7 for 30 days.
