Better than 5 stars!!!!!
We had our Generac 20kW and whole house switch installed in March 2014. Ever since the install we have been hoping for the power to go out (strange yes but wanting to test the investment). Finally the power went out during a thunderstorm Sept. 1st. The generator started confidently just like it does on it's weekly exercise runs. We were so pleased that we did not need to drag out the old portable generator. During the 6 hours of outage we ran, 3 TVs, 3 computers, the dishwasher, the AC, 2 fridges, 1 freezer, the sump pump, the well pump, the garage door and almost every light in the house at varying times. The Generac never missed a beat and was so quiet when it was time for bed nobody complained like they did with our old portable. Fantastic product. Exactly why my parents and in-laws installed their's a few years ago.

Just finished 12 days of flawless power after Sandy
After last year's hurricane here on Long Island knocked out power for several days leaving our sump pumps useless, we purchased the 20k unit...couldn't have imagined it would be running for 12 days straight less then a year later!
Our power does get knocked out pretty regularly, and just last month the unit was running for 5 hours. I recently had the radio remote installed, right by my home alarm keypad. I'd highly recommend it, as it gives you the added peace of mind knowing the unit is ready to go without going outside and opening up the unit.
Excellent unit, would highly recommend it.

Great Price for a Great Product
Generator arrived quickly, all parts necessary to run included. Documentation was excellent. Only hiccup was the software install, it took 28 of the 30 minutes allotted to finally login with the WiFi. I think there can be a quicker way to do this. Come on guys, this product is designed to be outside out of site, the WiFi has to be better, more range. It took almost 15 minutes for updates, how about having a download site and let us use a USB drive to transfer, that would take what 2 minutes?
Don't get me wrong this is a great product and I will sleep better after today

Very happy
We are very happy with the installer that we had for our Generac generator placement. He was very helpful and friendly to work with. We like the Generac product and look foward to many years of service with it.

Peace of Mind
Our Generac was installed a few months ago, and with all the set up and testing -- we are now ready for whatever the weather throws at us. We had one real-life outage so far and we froze, listened, and the power was on again! We love the peace of mind this gives us. Especially during these times of "staying at home".

This is a necessity for rural life with pumps
This gives piece of mind for me I can't count the number of times the power has gone out while we were out. This generator doesn't have me running home to get the generator hooked up so the basement doesn't flood again. Also as we are both getting up there in age it was getting to be a little difficult to pull the generator out and hook it up. No more trying to find the flashlights the kids had been playing with. This was one of the smartest buys I have made.

Not worth the money
We purchased our 20kw in 2011. 1st. the NEW battery was dead. We have faithfully serviced this generator. There seems to be something wrong with it constantly. Waiting for parts right now AGAIN. It is a good thing we have had a mild winter. Waited for parts last year that ended up costing us over $500.00. My husband & I have decided that this was the biggest waste of $8000.00 . We could of gotten more pleasure taking a great vacation, instead of wasting money on this Generac stand-by generator. I can see why it is called that, CAUSE YOU WILL BE STANDING BY WAITING FOR IT TO WORK.I DO NOT reccomend it. A WASTE OF hard earned money.
