Have not needed it yet

Can't give it 5 stars as I haven't needed it yet. It is nice to know that the test run functioned as it should when the houses power breaker was opened manually. So far, so good!

Great investment!

Living in Maine we experience the uncertainty of power outages. We are retired and the ease and peace of mind during storms has been wonderful. Wish we'd invested years ago.

excellent product

had generator install by class A electrical contractor. it was the best way to go. We have had 4 power failures since we hooked it up last Oct 2016. It kicked on exactly on its own and shut down when power returned. Could not be more pleased...

So far it does what it is supposed to.

Since install it has turned on twice for power outages. Both times within a minute power was restored in the house. No longer have to run extension cords around the house like for old portable generator.

Ran well on the test

Our electrician ran a test to be sure all was connected and working and the generac performed as it was intended. Other than that we have not had a performance.

It's neen 1 year since my install and all is great! we lost power a couple times and without fail the generator kicked in! So nice not having to worry about sump pumps, freezers, etc. Worth the investment!

Peace of mind goes a long ways. have not have cause for my 22k generac to kick in. But the peace of mind is sure worth the investment..

we have not had the outage that would require the generac 22k to kick in due to power loss. But I have to say just knowing it is there, has caused a huge peace of mind

Works every time Perfectly

Have had 3 power outages in the last month. Generac system worked perfect each time. On and off automatically, no intervention needed. I wished everything worked like that.

Works like a charm.

I have only had the opportunity to use her once, and she worked like a charm. Power was out for 3 1/2 hours, and my genie kept all of the power going. Fantastic. That's why I bought her!!!!
