Control your power. Control your life.

Rated 4.8 out of 5 by 273 reviewers.
Rated 5.0 out of 5.0 by Fantastic! What peace of mind! Power goes out. Generator comes on within 15 seconds. Entire house has electricity again! No worries. Fairly quiet. Considering what it has to do (power an entire house) it is extremely quiet. June 27, 2016
Rated 5.0 out of 5.0 by Not one thing we don't like about it! This is our second generator I wish we would have hot a Generac the first time. I can not find one thing to complain about. Now my father and my sister have gotten one also. We look forward to many worry free years. Great job! June 22, 2016
Rated 5.0 out of 5.0 by Product is very functional Got my Generac 4 years ago after a storm. I have been extremely happy with it. It is quiet . Lost power 2 times for a couple of hours and my power never skipped a beat. Thank you Generac! June 23, 2016
Rated 5.0 out of 5.0 by 15 seconds and this unit is powering the whole house The few times I have been without electricity, this unit performed flawlessly! June 23, 2016
Rated 5.0 out of 5.0 by Best money ever spent This system is by far and away the best investment I've ever made I would Recommend to everyone go big or go home. This thing will run a small city May 5, 2016
Rated 5.0 out of 5.0 by 20 KW runs the whole house We had the 20 KW unit installed in May 2014. It performs the weekly self test/run every week without fail. In addition I flip the main breaker maybe a couple times each month and the unit kicks in and runs the whole house. Last year during the summer a tornado/high wind event came through the area and the power went out for three hours but the Generac came on and ran two air conditioners, pool pump, pool heat pump, refrigerator and TV for three hours no problem. It eased the anxiety associated with the event. It worked just as well through the cold New England winter, starting and running with the cold weather battery warmer option. December 15, 2015
Rated 5.0 out of 5.0 by Works great! Almost instant transition when the power goes out! When the power goes out, this product click right on and we have power back within seconds. Although we don't have everything connected to it, we have everything we need and forget that the power is off. No complaints! February 26, 2016
Rated 5.0 out of 5.0 by Peace of mind I recently had my generator installed with the transfer switch. Luckily I haven't needed it yet, but knowing it is there feels great! January 31, 2016
