Great product, great installers and retailer.

Our generator was installed in 04/2026 its been great. I does it's self check every Saturday at 8am as scheduled. I keep hoping for a power outage so it can do its job.

The feeling of safety and security...

We bought this generator a year ago when we built our new house. It was one item that my wife and I wanted to be sure we had whole house coverage during any electrical outage, being that our new house was almost all electric.

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.

Generac Generator Love

Best money spent! Based on my Generac Generator I have recommended Generac Generators seven (7) times that have resulted in five sales and installations.

Ready when!

I've owned this unit for over a year now and it was purchased through Costco. It has kept the power on a few times for short outages, without fail. No hurricanes yet and hopefully we won't have any, but, I'm ready if when we do.

I've always been impressed with Generac generators, so they were my only desire when we were financially ready to purchase a whole house emergency generator. We have a DD/ID adult son, so having one was important to us for his sake.

Whole house backup power

Haven't had any lengthy power outages since installation. Yet to undergo any lengthy running episode. Wifi not very reliable regarding connectivity and usability.

Solid unit with a good reputation

Really good product. Installation was good and looks professional. Only issue I have is the extra cost per year to get full functionality from the App…

Great investment

Had this installed about a month ago and a couple of weeks later it worked as designed during a short power outage. We have peace of mind for the upcoming hurricane season.
