Rated 1 out of 5 by from Problematic Total garbage, my 22kw didnt even last 2 yrs. I had a total of 3 outages with non lasting longer than 30 mins. The last one the unit started, ran for 15 mins and died. The 7 amp fuse had blown in the control board and the engine seemed excessively hot. My installer came out multiple times and were unable to fix. Generac was absolutely no help at all according to my installer. They sold me a lemon and wont stand behind their product. I would love to hear their excuse 8 mos later I have a generator thats a worthless peice of garbage. Thx Generac

Rated 5 out of 5 by from Excited to use our generator! We had our generator installed yesterday. Everyone who worked on getting it set up was professional, explained thoroughly & easy to talk with. Excellent job! We're excited to be worry-free when we have bad weather. Easy to use & excited to use it when needed.

Rated 5 out of 5 by from Great value for all we get from it We had this installed at our elderly mother's home to offer the security she needs. She is on oxygen and her battery-operated oxygen generator will only last a few hours. Not only does the generator itself offer piece of mind but the fact that we can see via the app that everything is working properly adds a whole new layer of assurance. In addition, the monitoring service helps the whole family sleep better knowing that our mother's needs are being met and it is hassle-free.

Rated 5 out of 5 by from Excellent product The generator has performed flawlessly each time we have lost power. It's a great source of comfort knowing we have this backup at the ready. We were concerned in advance about how loud it might be, based on some neighbors machines, but our Generac is considerably quieter than we thought it would be.

Rated 4 out of 5 by from necessity in cold weather, wi-fi not understandable We live in a cold climate and now that we are old it can be dangerous in sub zero weather to be without power. The last storm we were out 5 days which also means no well pump no water. Huge expenditure with the cost of install for old people. I have not been able to get the wi-fi remote monitor to work as I am not tech savvy, do not understand what they are asking for to be able to follow the instructions, nor can I climb thru the snow banks to get at the generator itself.

Rated 5 out of 5 by from Best decision ever!!! Only had my 24kw for about 1 month, then after severe storms we lost power for 5 days straight. Having a newborn/toddler was one of the main reasons I chose to install one but honestly is a great choice for everyone! Our lives never skipped a beat, it ran our whole house seamlessly including all appliances, our 5 ton a/c unit and even our heated inground pool! Other than the destruction from mother nature you would never have known we were without power and could go on as if nothing happened. Thank you Generac!!!
