Rated 4 out of 5 by from This product performs as advertised Everything was as expected. Initialization was excellent. The only issue I had was the cost of the 5 yr maintenance plan. I hope I am not disappointed with a plan that cost over two thousand dollars. It was kind of quietly inserted in at the last minute. Makes me a little wary of any new Generac products that may be coming to appear.

Rated 5 out of 5 by from This product can run the electric for our house and barn We purchased this unit to run the electric to our house and barn after Hurricane Irma last year, during which we lost power for weeks and could not pump water from our well for drinking water or bathing, not to mention running air conditioners or a refrigerator. Highly recommend contacting Jon from One Stop Generator Shop for whole house generators, and we really appreciate Rich and Matt who did excellent installation job. Oscar the gas hookup person was very good as well.

Rated 4 out of 5 by from 24KQS is much noiser than or other one 24kQS ruin much louder than our other one, our other one is a 22kQS about 8 years old and you have to walk up to it and place your hand on it to confirm if it is ruining. The New one you are able to hear 200 ft. away. The installer thought it was normal and said the stander is much nosier.
