Rated 5 out of 5 by from back for more We are replacing our over 20 year old Generac with a new and more efficient model. Our old generator was still performing but we decided not to go through another winter with it. We look forward to another 20 years!

Rated 4 out of 5 by from Generac Bolts? I have been out of the country and am just now going over all the product information of the Generac. However, since the outside of the unit is all aluminum, and I do live on the river, how come the bolts on the inside of the generator are not rust proof. For a few dollars this could have been a rust proof product. I just bought this new Generac as my previous one rusted away which was 12 years old. The motor and generator were perfectly good but not the frame and shell. I plan on asking your CEO this question. Of course, you could forward this to him or her. Thank you.

Rated 4 out of 5 by from Looks great; but still to early to tell Replacing an older model generator. New one is quieter and runs cleaner. Installer did a good job. One con, and probably my fault for not having researched deeper, is that the cool App to monitor and change your system requires a subscription fee of over $100 year.

Rated 5 out of 5 by from New Build Install The product was just installed as part of our new home build. The technician explained it. It seems very easy to operate and looks fine sitting in the backyard on its stand. Works fine. We’ll see how it does the first time a hurricane knocks out power for an extended time

Rated 5 out of 5 by from Quality product with a trusted name We have a Generac at home so it made sense to have the same sense of security at work. This 27 kW model will power the whole building, it runs on clean burning propane and is very quiet when running. We now have an added sense of security knowing we will have uninterrupted power at our facility.

Rated 4 out of 5 by from Where's the Beef (WiFi) ? At this price point, and at this point in time (technologically speaking), why in the world doesn't this product come with WiFi built in??? !!! Have yet to receive my product run through/orientation from the installer - but I'm sure it will be a welcome addition to our home.

Rated 5 out of 5 by from New installation I just had my new Generac generator installed last week. As far as the overall rating, it has not been engaged yet due to a power outage, but I am quite confident it will be wonderful. The company that installed it were incredible. Extremely professional and efficient.

Rated 5 out of 5 by from Easy This is my second Generac generator. The first one was so easy and they stood behind the product so well when the exterior had some issues they sent me out a whole new case for my generator and I’ve been using our current one for 10 or more years so when we built our new home it was easy to decide that Generac would be the generator we would purchase again. We have a full power service for a 9000 square-foot home 15,000 overall square feet.
