Comes on when needed without worry.

Works as promoted. I don’t have to worry about my gasoline generator needing a start in the middle of the night or refueling at zero degrees.

Waiting

Professional installation, good looks, haven't had to use it yet, but I'm sure it will work as the exercise mode has never failed.

Rock solid and there when you need it!

Reliable and great mobile app. Upgraded from an older less powerful Generac and glad we did! We have a B&S unit at another property and it is junk.

Great product

I've had the unit for just over a month and in that time we had power failure. The unit worked fantastic.

Great product

I have professionally installed several Generac with all of my customers having great experiences. I finally decided to install one at my own house.

Could be better

The generator and automatic transfer switch seen to work properly. The wifi and cellular devices do not work.
