Rated 5 out of 5 by from Good Generator for home backup I replaced a Kohler backup generator, because it just wasn't stout enough for the job. This new Gererac generator was easy to install and runs great. I have tested operation and have no complaints. I really like that fact that it runs at only 1800RPM. This was the problem with my old generator. It had to run at such a high RPM rate in order to meet the demand, it just wore itself out. Only took two winter to do it. The new generac 27KW generator is built with the idea of endurance and long life. Couldn't be happier with it. Highly recommend this series of generator.

Rated 5 out of 5 by from Initial review is very good Installation was fine and initial tests were good. It remains to see how the system functions over time and the amount o service necessary.

Rated 5 out of 5 by from New Installation We recently had our system installed. The crew was outstanding and even finished 3 weeks ahead of schedule. Is it wrong to hope for an event to see it in action? After two hurricanes with extended outages, we are thrilled to be finally protected in the future.

Rated 4 out of 5 by from Quiet generator I haven't needed the generator yet but we're only in the first week of hurricane season. It's nice to hear the weekly test take place, even if you have to go outside and stand by the unit to hear it run. So quiet you can't hear it run from inside the house.
