Features & Benefits:

The Guardian 11 kW self-test runs for only twelve minutes.

I just replaced the same wattage generator with this new ATS generator. I cannot tell you how well this worked. It was installed two days before hurricane Matthew. We got through the hurricane with no power loss. It was the day AFTER that the power went out at 2 pm and was out for 8 hours. We didn't miss a beat at home. This took care of our 2200 sq. ft. home including the AC! And the noise level in half of what my old unit made. My next door neighbor commented on how low the noise was. I would tell you this is a GREAT price to have the peace of mind knowing you won't have to sweat it out (Florida) during the next power outage.

This is a perfect size for this new ranch house we built. The sound level is great for a village house.
