Best genset for residential use!
I'm a 64YO C-10 Electrical contractor who's installed over a hundred back up systems, from Cat to Onan. But for dependable residential application, this can't be beat.

Excellent
Just in time for hurricane season. My 22kW Generac Generator was installed about a month ago. works great but has not been tested for an extended length of time as no power outages yet. I did a lot of research before purchase and this was definitely the generator to buy. Arrived in 3 days. I would purchase from this website again.

Poweroutage and It Worked Perfectly
A little late in writing my review for my Generac 7043. Installed last summer but no power outages until last weekend. Powere went out due to a wind storm. Lights flickered then went out. I waited and started counting on the count of 7 all power restored. Perfect. I had a lot of friends as the power was out for 22 hours. Love it.
