CUSTOMER REVIEWS

Rated 5.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Excellent unit/very quiet Our unit is large, but blended well into the area where we have the exterior A/C units. We chose a unit with a large but slow RPM natural gas engine. The slow RPM lead to a minimal amount of noise when in use. I recommend staying with a dealer listed on the generac.com website, because you will get expert installation plus service after the sale.

Rated 5.0 out of 5.0 by GREAT UNIT 48KW POWERS MY ENTIRE HOME, PUT IN GEO THERMAL HEAT AND COOLING, UPGRADED TO THIS UNIT FROM A GENERAC 15KW FOR THE EXTRA POWER OF THE ELECTRICITY NEEDED...., I USED THE SAME 200AMP AUTOMATIC TRANSFER SWITCH THAT WAS PREVIOUSLY INSTALLED. I WOULD NOT LEAVE MY FAMILY ALONE WITHOUT IT. VERY DEPENDABLE. NO WORRIES ABOUT POWER WHEN I AM GONE. EXTREMELY QUIET OPERATION, REALLY DON'T KNOW THAT THE UNIT IS RUNNING! WITHOUT A DOUBT, I WOULD RECOMMEND THIS UNIT TO ANYONE INTERESTED IN HAVING THE PEACE OF MIND OF NEVER AGAIN BEING WITHOUT POWER DURING AN OUTAGE. October 7, 2011
Rated 5.0 out of 5.0 by excellent choice Upgraded from 20K which was adequate for necessities of large home to this product to run entire home, outbuildings, and new enclosed pool. So far, so good. Electric off only once so far and started up within about 20 sec. Gives me security and ability to carry on routine necessary activities without interruption. May 2, 2013
Rated 5.0 out of 5.0 by Awesome machine!! This thing is awesome. We lost power and within 10 seconds the house was up and running. The kids didn't whine and cry about not having internet. I was able to charge my cell phone and thus able to contact the power company to find out an equipment malfunction caused the power failure and we would be back on about 4 hours later. Record heat would have made those four hours miserable!!! Thank you Generac for an affordable alternative to suffering through it! August 24, 2011
Rated 5.0 out of 5.0 by The generator is a source of a great sense of security. It operates as advertised and efficiently. The generator is a source of a great sense of security. It operates as advertised and efficiently. October 7, 2011
Rated 5.0 out of 5.0 by Great generator powered 8000 sq. ft house for 66 hours after power outage from hurricane Irene without a hiccup August 30, 2011
Rated 5.0 out of 5.0 by This is an excellent standby generator. It is much quieter than an older 10KW portable unit I have been using. I have no complaints at this point. Features and performance are as good or better than advertised. Only time will tell about the overall reliability, but so far, I consider everything to be as expected. I originally researched the 22KW, and the 27KW units which would provide adequate power most of the time. Load-shedding would have managed any conflicts. I felt like the turbo-charging of the 2.4L 4-cylinder 36-KW unit would degrade reliability over time. I am very pleased with the 5.4L V8 Ford Windsor engine in the 48KW unit that I purchased. It appears that it is the same engine that is used in the 2012 Lincoln Navigator and Lincoln Pickup. My wife has driven Lincolns for the last 20+ years, and they have been very reliable. My installation contractor did an excellent job, and also load tested the unit up to 80% of it's rated capacity, and performance was excellent with no strain on the engine. LP gas pressure was well within the required range at any load, and LP usage was very reasonable during the 1-hour load test, and approximately 5-hours of running my entire home on a 100 degree day while waiting for my local power company to come back and restore utility power following the cutover and inspection. LP tank volume decreased less than 1% from a 500-gallon tank. If no one hears anything else from me, it's most likely that I am satisfied to the point that I don't think about it any more.
