Rated 5 out of 5 by from Great Generator Just had installed on Thursday... Love the quick view of the "green" light that I can see from inside the house that all is working well

Rated 5 out of 5 by from Great product! We live in a rural area and had a few multi-hour outages over the years, one that was rather inconvenient. Now we have peace of mind. I did the low-voltage wiring for load-shedding relays on the transfer switch and the installation instructions were great. An electrician and the gas company took care of the hookups. The dealer did the final startup and tests, all went smoothly. Generator is relatively quiet and handles everything we need! Just added a couple of battery backup UPSs for the computer and TV and all is protected and power outages are a thing of the past. Now the funny part of the story. The day the generator was delivered, I told the guy that we had pretty reliable power and rarely had outages, which I attributed to our neighborhood underground service. Just after he set the generator on the pad, the power went out, for 18 hours!! I could only look at the generator and think this won’t happen again...and I should have ordered it a week earlier. The underground service, though impervious to falling trees and car accidents, still can fail and took a lot longer to find and fix the issue.

Rated 5 out of 5 by from I love the fact that we do not have to worry about power outages anymore! This product is so dependable The installment team from H.O. Field Electric were super professional with all of this and so friendly, explaining all of the features and then re-explaining them to me (the wife) as well.

Rated 4 out of 5 by from Generator review Just had it installed today. Installation went very well, employees were prompt, professional, polite and very pleasant to work with. Explanation of overall features and how the generator works very detailed, yet easy to understand. Will be happy to provide further review after we have had the unit for 1 year.

Rated 5 out of 5 by from Beats my old portable generator Had an old portable gasoline generator that only powered a small portion of my home. Now the smart modules will allow us to utilize all the appliances in my house.

Rated 5 out of 5 by from Peace of mind The ease of acquiring this generator and its installation was easy! After the hurricane last year we vowed never again to go 11 days without power, therefore no water. My sister and I have peace of mind which is invaluable- thank you!

Rated 5 out of 5 by from Great value and peace of mind Ordered the 22Kw with transfer switch. After a lengthy outage recently, we decided 'never again'. Living rural is great but sometimes the coop power can be influenced by ice on trees or other powerful weather events. Very pleased with the fit and finish of the Generac. First time test was great and the setup for automatic protection was a breeze. The crated generator had no missing parts. Best of all - Generac is made here in the USA. Can't beat that.
