Rated 5 out of 5 by from Performed flawlessly Had our 22 kw liquid cooled Protector QS installed 4 years ago. Don’t remember if we ever had any outages longer than a day or so. It has always run great. We got the true test during Hurricane Laura. We left the morning before the storm hit. It was nice to comeback to a home with minor damage and a generator running just like it was supposed to. All in all it ran for 7 days and never missed a beat. Thank you Generac for making such a quality product. FYI , scheduled maintenance was performed during the outage.

Rated 5 out of 5 by from 7Years old and still going strong I've had my 27KW for over 7 years and it's still performing excellent. We have the annual maintenance with our generator installer (Reliable our of Deerfield FL) and I could not be happier. Two years ago, it ran for 10 days consecutive and never missed a beat! Highly recommend.

Rated 5 out of 5 by from Natural Gas 22KW I live in south Louisiana and have been plagued by un-reliable electrical power. It seems that most storms, of any size, disrupt the power and on average it will be out for a minimum of 6 to 8 hours. My area is usually the first to ho out and the very last to have power restored. My Generac 22KW QS unit works great. We have had 3 power outages in the past year, and the generac unit picked up and handled the load without any problem.

Rated 3 out of 5 by from Not very "rain proof" for claiming it's a "rain proof enclosure". We had this generator installed at our new house summer 2019 running off a 500g LP tank that also supplies LP to appliances. Overall I enjoy the generator. It tests when it needs to. It is quiet which is why I chose this one over the air cooled. Being in country I didn't want to disturb neighbors and wildlife with the horrible loudness of the air cooled version. My biggest and only real issue is that although the enclosure says it is rain proof it is not. We had a moderate rain yesterday afternoon for about 20 minutes. Wanted to check on things, opened it up and the foundation was clearly wet. Water came in on both sides (door sides). Not enough for it to be standing but enough to still be wet. When I opened the side doors water also dripped down the insulation. I would think a simple "gutter" or lip above the doors would prevent that from happening. So simple I believe it to be an oversight. For the cost of these units I would, and do, expect it to be rain proof if it claims to be so. I also think adding a bug screen to the louvers would help stop bugs from making their hokme inside. I spray insecticide to prevent that but i shouldn't have to. With all that said I cannot decide if I can recommend this generator or not which is unfortunate because this was probably the most exciting aspect of the house-build I was looking forward to. Living with unreliable power durijg even minor storms in southern Texas I knew we needed more than a gas-powered generator to get us by during storms and hurricanes.

Rated 5 out of 5 by from Customer Support Chris Braughton came out immediately and explained the installation process along with an affordable maintenance plan. He also answered my questions about my generac. Very professional, and I'd recommend his service to anyone that owns a generac.

Rated 5 out of 5 by from Glad I waited for the QS Generac So we commissioned the QS 22kW yesterday and it fired up immediately and ran quieter than I anticipated. I would compare the noise level to our newer AC unit on the ground; not bad. I'm glad I chose the QS over the air-cooled unit. The additional cost was well worth it imo. After simulating a power outage, the unit came on in less than five seconds and purred. The lower rpm and the liquid cooled four cylinder engine makes a huge difference and once the cowling was closed it got even better. I'm anticipating a longer maintenance cycle and reduced fuel consumption based on what my electrician who has had both told me from his experience. I would strongly advise to have a licensed electrician who has experience with standby gens do the hookup. This job is NOT a DIY project. Good luck!

Rated 1 out of 5 by from POOR. Very unhappy with our 11KW We’ve had This unit for just 5 yrs. At least 3 of the yrs. it has not run properly or has not run at all. Each power outage it goes into Alarm mode and we have no power. So Once again we call in a repairman. Each time the code reads the same, but supposedly each time there is a different issue. S.S. Can’t afford to keep sinking money into this unit. Nor can we afford a new one. Your “contact us” button does not work. So here it is.
