Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Quick response, noise level could be better Works excellent! Had two power outages in my new construction home in a remote area of town. Soon as the power went out the generator kicked in without a pause. Our washing machine was running at the time and it didnt even reset itself. Well-built machine and easy enough to maintain. Worked well with my propane energy source. Only wish it could be much quieter.

Rated 1 out of 5 by from Highly Susceptible to Ant Investation During the first few months of operation outside of winter, ants were attracted to the unit, and infested the circuit board. This resulted in the unit activating randomly when there was no power interruption. This could have resulted in a loss of all my propane (it is at a vacation home) had I not arrived when it started. This resulted in a substantial service bill and the company declined to cover it under warranty despite being a known issue (if you search the internet for Generac Generators Ants). If the risk had been explained, then my issue. But, I had no idea. Very disappointed in this company and their supplier!

Rated 5 out of 5 by from 20 kw Seems to work fine, except for me it is all manual, and I would like to get the installation wizard to show test dates, warranty time, etc. I'll call customer service some time.

Rated 5 out of 5 by from Excellent product for the price. Purchased this unit to help with winter power outages. Live in a rural area that sometimes takes hours to get electricity up and running. This will ensure heat in the winter and cooling for freezers in the winter. Installation was done in a few hours by and excellent crew and the test run was great. No more blackouts for us.

Rated 5 out of 5 by from 20KW unit provides the power needed with reliability Installed the 20KW unit to power seasonal maple sugaring pumping facilities. Needed a unit that was reliable. The cold weather packages provide extra assurance that it will function when needed in northern Vermont sugaring season. This is my second generac unit; the first was a 27KW unit which has proven reliable when power went down during sugaring and it powered the vacuum pump, the reverse osmosis machine, evaporator and filter press. The 20KW unit replaces a tractor pto winco generator which worked but required setup and take down time whenever needed; the automatic transfer switching of power to the generac units saves me considerable time when time is at a premium.

Rated 4 out of 5 by from Performs as promised Excellent design with one exception, exhaust exits within the enclosure. Just replaced a Generac unit with a rusted out enclosure due to exhaust exiting within it. Modified the exhaust to exit outside the enclosure and now expect the generator to last my lifetime. Thank you, John
