Never Worked

Piece of crap. Never worked when needed. Continues to give default message. Either a lemon or improperly installed.

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.

Love our Generac!

Awesome system! You do not realize how nice it is to have a Generac generator until the power goes out! Full power back on in seconds!

Dependable and Meets Demand

The unit has performed as expected and has met the whole house demand during several power outages over the past twelve months.

Works out of the box

Instructions for setup were quite clear, my unit replaced an older model 22 kW unit which contributed to my knowledge base and ease of setup.

Powerhouse beast!!

Bought the 22kw generator, and we feel so relieved when the power goes out, that our Generac will start, and transfer power over to the house within seconds. It powers the whole house with ease. The 3 ton central A.C., double wall mounted ovens, all 4 burners on our glass cooktop stove, and well pump. It's like we've never lost power! Also, when utility power comes back, it transfers power back with zero interruption! Love it! Thanks Generac!

Peace of Mind / Quality / Convenience

Living in the heartland, "...where the wind comes sweeping down the plain...", and the ever present possibility of bitter cold and ice storms in the winter, the threat of power outages is high. We experience a mean average of 5-7 outages a year. Those outages can last minutes to days, anecdotally, 2-4 hours in my experience. No more portable gensets, no more stored gasoline, no more extension cords and inlet boxes, no more breakers and interlocks. No more fighting the elements to get the power back on. Generac does all that automatically and in about 15-20 seconds. That friends, is peace of mind!
