I self installed the 20kw unit myself with some help from a friend who is a sertified electrician and fellow firefighter! My biggest problem was getting the LP gas co. line to the house in a timely manner ( 3 week wait)! "Good experience overall tho" Don---B.S. Mi.

The Generac Stand By Generator is well known in the market place as a best in class product. The residential product line is well designed, scalable to meet the needs of the household, and the operational features are excellent. I am very satisfied with my purchase of this equipment.

I recently had a 20kw whole house generator installed in my house. My wife and I had discussed for a few years and finally went ahead with the install. We could not be more pleased with the finish product or the install. The quality of the job by Cornerstone Power Solutions was excellent. Very professional work. We are now fully prepared for any outages we may experience in the future!

We just had our generator installed and I was worried about how noisy it would be for my neighbors to hear. I was surprised and elated.. it is only as loud as the lawn mowers that are used to mow my lawn. I could see the sound insulation inside the unit and also the rubber pad on the bottom of the outside of the unit to help decrease the noise. Inside the unit, the components are easily identified and to get to if needed. I am extremely pleased and I highly recommend this unit to others

I haven't had the opportunity as yet to experience its efficiency, but the generator has completed its check runs each week and I am very impressed by the quietness of the generator. It's appearance doesn't detract from the home/landscape appeal. The service personnel who came out to install the generator were courteous and very respectful of the area they were working around including when they needed to come in the home. I am very pleased with my decision to buy and install this generator.

I have to look at it in this fashion....we are entering hurricane season. I could have powered all 110v in my home with a 5KW Unit. but I'm almost 84 year old...too old to be messing with gasoline. The generator is like a security system....there, but hopefully will not have the occasion to use it. We lived 3 weeks without power after hurricane Hugo in 1989...So, I;m prepared! Ask me again after hurricane season.

We had the generator installed just before the storm just in case we lost power. We did not have to use it but we were pleased that it came on just for the test prior to the storm. It is a good looking unit. We look forward to many years of protection of our household appliances during power outages.

Our electricity has gone out several times since I bought the generator and I am the only one in the area who had electricity. It worked perfectly. Now the neighbors call me to see if my generator is running so they will know if its just theirs or if everyone's electricity is out. Never mine!! :-)

This is my second generic generator the old one servered my family well for long time. Now I bought a new one which is very nice ,easy operating, better external housing, better over all design now hopefully this one give us the same good service like old one did for years to come.

Purchased for a home health medical facility that requires automatic operation during power outages. Great unit, operates perfectly. I'm a fair hand at electrical but this install requires the tools and knowledge of a licensed electrician. I spent $3,600.00 on parts and labor, but I am in California where everything is more. Total time for power to switch is 15 seconds.
