20,000-Watt Air Cooled Home Generator System with Symphony II Dual 200-Amp/Split 400-Amp Automatic Transfer Switch is rated 4.7 out of 5 by 49.
Rated 5 out of 5 by from I'm happy with my GE 20kW generator After looking carefully at the Generac, GE, and Cummins generators, I settled on the GE 20kW model for my home. I live in a fairly large three level house in the mid-south; I have two air conditioners and a heat pump. I was initially concerned that I'd need to buy one of the bigger four cylinder generators, but after talking to a few folks, I decided the 20kW would meet my needs. I power the generator using natural gas, so the actual rating is 18kW. I had the entire job done by Paul K Young Electrical (501 AUTUMN CHASE CT, INMAN, SC 29349, (864) 331-9730). Paul did all the work, from helping me choose the right generator to testing it to make sure everything worked properly. During testing, we started up all three AC compressors, my hot tub (with all the blowers on high), and left everything in my house plugged in and running. When the A/C compressors kicked in, there was the briefest (less than a second) surge in generator engine load, then the engine continued to hum smoothly. With every load on, Paul measured generator output at 42 amps - leaving 33 amps to power more stuff before reaching the max output of 78 amps. I couldn't hear any audible evidence that the engine was loaded - it sounded the same carrying all the house loads as when it was idling. I had three load-shed switches installed, and they effectively sequenced the main loads. There's a remote indicator that confirms all systems are go that comes with the unit - nice to have, since I might not look at the generator itself often enough to notice a warning light there. The Generac system was a a little cheaper, but I was concerned about its load management capabilities (dimming lights, etc.). The Onan-Cummings generator was interesting; I particularly liked the reduced noise output, but didn't like it's load sequencing options as much as GE's. It would have cost about $1000 more, so the noise reduction didn't seem worth the cost. The GE sounds like a lawnmower; when the guys came through to cut my grass yesterday, the noise from their mowers was significantly louder than my running generator. All in all, I'm very satisfied with the product, and would strongly recommmend Paul Young as an installer.

Rated 5 out of 5 by from Generator with the biggest Bang for your Buck! After doing extensive research, and installing a Generac Gaurdian and having it fail when I needed it most, I was led to this wonderful machine by my authorized dealer. I had this 20kw GE whole house generator installed a few months before Hurricane Irene. Not only did it preform amazingly well, when Sandy came around it was like it had never even hit (having 4 families stay with us on the other hand.... ) :). I consider myself a generator aficionado, and trust me when I tell you that this machine is the way to go. I do, however, recommend that you have it installed by an authorized generator installation company, because it makes a big difference in warranty and service coverage.

Rated 4 out of 5 by from Not a Bad Generator. It really is your best bang for your buck. You can't beat the 5 year warranty. Everything in it is Briggs and stratton, with some "special touches" from GE. Within 6 months the voltage regulator on the board causing the starter to burn out. This was replaced very quickly within 24 hours which is great. You can't really judge a product based on that though. Other than that this beast powers the whole house, 2 furnaces, and 2 Acs with plenty of power left over. When it works its a solid 4 stars with the following annoyances: 1) We live downtown and during an outage would like to turn off the generator at night so not to waste fuel and disturb the neighbors. The only way to do this is to walk outside and hit the off button. It would be nice if there was a automatic cool down period after hitting the off button. It also would be nice if we could wire a on/off switch inside the house. Instead its attached on the board. 2) Since we will loose power for maybe 30 seconds in the middle of the night all the time, i keep the unit turned off unless we need it. If its not turned off we hear the thing fire up for 5 mins. at say 3am and its annoying. It would be nice to adjust the turn on delay and set it for maybe 15 min, if the unit senses no power. Or even better, if there was a way to wire a timer to the unit so the unit will not turn on between the hours of 11pm and 7am. 3) The exhaust points straight down and the hot gases absolutely kills the lawn. Surly there was an easy way to have the fumes shoot up so it also does not catch rain. Now as a home owner, i need to live with a large swath of dead grass or oddly place some sort of landscaping stone around the unit. 4) If we had a large yard with no neighbors it would be very quite. However, our bedroom is by the unit so we hear it turn on. They could make a slightly oversize housing, with extra insulation inside to make it more quite. I would gladly pay more for that. 5) I change the oil myself it in. It would be nice if the drain hose was longer. The way the unit sits on a pad, its hard to get the hose down into an oil pan with out using another say 8" of random material to get the oil down into the pan. I had it professionally installed so i would imagine the install was pretty run of the mill. These units can burn oil, so if you have a storm coming, you might want to check the oil level before the storm. Over all, you can't beat the warranty , in my eyes when you buy a piece of equipment like this, assuming all performance specs are the same, the warranty is where its at.

Rated 5 out of 5 by from Have this installed by a certified installer I have seen many reviews with people reporting some issues. I hired a pro that was factory certified and trained. It wasn't cheap, but I was enjoying life during Hurricane Sandy while my neighbors who hired "electricians" were annoyed that their generator wasn't working properly. My priority zones were great and I was protected from any issues with the smartest investment I made. As for the question about 5 ton air conditioner, my installer informed me that it is a known issue and my 5 ton AC worked fine on generator power. No issues whatsoever. Key is having the professionals installs this generator.

Rated 2 out of 5 by from Constant engine problems I have not had the generator for a year yet. It always ran rough, then during a blizzard last February it ran for 17 hours and quit.  Luckily the power was back on about an hour after that.  Now it will not run.. The installer has replaced the circuit board twice.  Since it is now almost November and I will have to have the whole thing disconnected for construction of a garage, I may not have it at all if there is a big storm in the next two months.  I am thinking perhaps it is a lemon, or I should have chosen another brand. If I am without power I will have to leave my house, this is why I paid SOOO much to have a 20Kw whole house generator installed.

Rated 4 out of 5 by from Saved our bacon from Hurricane Sandy Felt like the smartest guy in the world when the generator kicked in early during the arrival of Sandy. Everything inside the house functioned exactly as if the power had not failed. I was a little disappointed that the engine consumed enough oil after 3 days of continuous low-load operation to shut down, but it was quickly solved with 2 extra quarts. I'll be sure to keep a few spare quarts on hand, but frankly I'm hoping she won't need them after less than 100 hours of operation next time. I had to install this quite close to my home due to zoning and building code; I wish the sound insulation were a little better. It's still a lot quieter than a gasoline-powered portable. All in all I'm very very satisfied and looking forward to beating whatever power failures mother nature will throw at us next.

Rated 4 out of 5 by from Solid solution for large homes, and no worries I wanted a whole-house unit that could run everything and do so reliably. This unit’s 83.3 amps of power is more than sufficient for my multiple refrigerators, two HVAC units, 3 dishwashers, sump pump, tons of electronics, electric car charging, and so on. The transfer switch automatically and safely switches the unit on and off quickly and has worked very well for the times we have needed the unit. Only complaints: had to increase the amount of natural gas coming to the unit by increasing the meter capacity and the line size to the generator. Also, the remote control “loses” its connectivity to the generator every once in awhile for no apparent reason even though it is less than 10 feet and one wall away from the transmitter.
