Great buy

Bought this 3 yrs ago for our cottage and guest cottage and it hasn't let me down. Being in cottage country power is going out regularly after the smallest storms. Just this week a tornado came through not far from our cottage and the power was out for 28 hrs, no problem, no issues. We built our cottage and my wife wasn't keen on putting one in, mainly due to the added cost of approx 6k. I insisted and what do you know, it came on sale and I saved almost one thousand, score!!! Great product, zero maintenance, always reliable.

I purchased the 22KW Generac and to this point I have been very impressed. I had this gen installed as a backup for my cottage. It has been used about 40 hrs now as I'm in "(Cottage Country)" . I have the built in wifi and it works great, always sends me an email when my gen is in the test mode or if power was lost. Always been a great reliable gen and also with the transfer panel it switches from elect to propane when the gen is running and once it shuts down switches over to elect heat again. Customer service is great and very pleased with my decision.. I leave the cottage with no worries of power outage and my water lines freezing up.

Reliable Product

I have been servicing generators since 2008, I found that Generac has only a few models that are reliable in our canadian weather. 10kW-22kW anything smaller does not seem to last unless modifed. I would also recomend a "cold weather kit" on purchase, as it is not included. Alex
