Today 11/20/22 Eversource lines went down, this was the first time other than running generator and testing load on gasoline. I setup the LP tank that was just filled and started up the generator. It ran with a THD of roughly Less than 1% which 8s good. We had about 2,000 watts on continuous power use, however the refrigerator would start and cause a spike in THD from 60.4 Hz to + 60.8 which caused all my UPS systems to switch over. Once stabilized the UPS shut off. However about 2 hours into operation the engine idle down, Even though the low idle switch was off and caused severe power fluctuations. I immediately disconnect our 50 amp breaker but no change in engine speed. I checked the LP line and tank, no icing with about 80% of LP remaining. I then opened the fuel valve and the gasoline picked up engine speed a little bit the gas LP switch was still on LP, I switched to gasoline, no change, I then shut the LP tank off and the generator resumed full power. After the power outage ended 5 hours in I went back on line power, and disconnect the 50 amp generator breaker. With the fuel selector switch selected to gasoline I opened back up the LP tank which immediately choked the engine down. The is a severe problem with the fuel selector and LP service line in the generator. I need this fixed please ASAP as this is a life critical backup device.

This generator is everything you think it is. It is large, and full of power. I purchased this generator primarily due to the fact that it has two 50A outlets. My home has two 150A panels side by side, and in order to make hooking a generator up easily and cost effectively, this was the generator for me. I have a 50A inlet per panel on the outside of my home, feeding a 50A breaker with interlock kit. This generator allows me to run everything in my home to include my 5 ton and 2.5 ton A/C units. The A/C units do have the Micro-Air soft start kits installed on them and I highly recommend them. If you are reading this review, then you know that losing power is inevitable, and the real question is how prepared are you? At literally less than 1/3rd the price of a whole home standby generator, this setup is an absolute no brainer. We have enough horsepower to power our home and manage the inconvenience. If you are on the fence, I can assure you that an investment in a generator is absolute peace of mind. This generator outputs < 5% total harmonic distortion which was a huge feature for me as well. If you are in the market for a large generator, you literally get what you pay for and this WGEN20000 is the cream of the crop. You will not be disappointed.

I did a ton of research on generators before I bought this, and I am so glad I did. I am very happy with my decision to buy this one. It puts out clean power so I don't have to worry about my sensitive electronics, it has enough power to run my whole hose. I feels this is the best bang for the buck for sure.

Just bought this 12000DF and it is packed with features and seems to be a solid build. Shipping was fast (2 days). Not that hard to take off the skid by yourself once you have the wheels on it...you just have to inventive. Also fairly easy to wheel around. However it is loud, no doubt. Glad I found this generator, will make life easier next time power goes out.

I purchased this generator to power my house and I also wanted the option of dual fuel, because with some of the power failures we have had in our area, gas stations could not dispense gasoline. This generator easily powered my home when I tested it. It easily supplied my two refrigerators, boiler, and a large air conditioning unit (the condensing unit and the air handler). This was done while running on propane. This generator is not noisy-probably as loud as a riding lawn mower. The generator is fits in the back of my garage, and for a man with a bad back, I had no problem maneuvering it.

I received the wgen12000df in a relatively short time after ordering. After initial setup, this thing fired right up. It had no problem powering everything I threw at it (all house led house lights, fridge, sump pump, fans, tv's, 3 ton ac unit, ect). I very impressed with how the generator maintains the 60 hz at various loads.

I just received my generator. I use it for work. Had a smaller on that was getting a little old. Always wanted a dual fuel but was scared to pull the trigger. Both fuels seem to be working just fine. It's a hoss. The guy asked me that delivered it how was i going to get it off the truck. I said im not

It's a strong & good running generator. Unfortunately the providing cranking batter is undersized and the one I received would not start the generator even after fully charging. Otherwise, it cranks great using a small Li-Ion jump pack. Will be contacting customer support.

Bought Westinghouse GEN. from Family Farm and Home. Owned a little over a year and it will not start (electric nor pull). Westinghouse is the Ford of small engines - DON'T TRUST THEM. GENs are easy to repair - fuel, fire and air, especially at a year old, but who has time for these games so early on? Not this guy, regardless of their warranty. If it malfunctions this quickly it's not considerable. No excuses. It means the design engineer doesn't care, thus the company doesn't care. Poor Q/C and design. Shenanigans. Will have repaired and sell if anyone will buy it. We wonder why no foreigners want to sell or buy American made products made recently.

Admittedly, I haven't tried powering my entire house yet. I just received the generator and tested it with propane and a hair dryer. But it looks and feels solid. I plan on updating this review after having a chance to fully test the equipment though.
