I bought this generator to use due to frequent power outage at my cabin. Have a heat pump, well and electric hot water. I received it and it was as advertised. Delivery was great. Easy to assemble. It started right up. I look forward to testing it with a load..

I would like to update my initial negative review but couldn’t locate it. Initially purchased a WGEN12000C in July of 2024 quit on met just 2 months later. Took it to one of their service centers in mid September of 2024 and after about 5 months and several replace parts Westinghouse finally agreed to just replace the generator. My original generator was no longer made so they sent me the WGEN14500C instead. I’ve had the new replacement generator for about 3 days now, so am going through the break in period and running on very light loads and so far so good. Fingers crossed, this generator will serve me well for many years to come as did my original generator that I had for over 5 years (WGEN9500DF). Getting a replacement was a very length process but I’m not sure if I could put all the blame on Westinghouse as I’m sure the repair shop has many other generators to work on as well.

arrived packed well, easy quick set up, the provided funnel for adding oil was a huge help, well laid out looks very well made, very solid, fired right up, quiet for a portable 12K generator. Very happy with my purchase. Replaced a smaller unit so I could run the whole house

Bought this unit a year ago to replace a WGen9500. WGen12000 puts out home electronics grade power unlike the 9500 model. Have had several power outages and works like a champ. Currently having a problem with a short in the wiring that blows the fuse when starting. Working with Westinghouse to get it fixed.

I got unit going in gasoline mode by following good directions and it works good . Noise level is no more than my lawn mower and 110v power receptacle works fine. I will check it in Propane mode tomorrow when I get a propane tank. . Dont expect any problems.

Just had this delivered and the setup was easy. Only a few steps and the instructions were easy to follow. Fired it up and after warming up 30 seconds or so it idled down to a quiet purr until I added a load. The panel is laid out well so that everything is easy to find.

i bought this power plant to help with power outages. It does more than I realized. I saw the smart switch outlet but didn't understand just what it would do until I read the user manual. actually turn on and off when the electricity fails. by itself. I haven't had to use it yet but i know i love it

I bought this Generator for a back up to supply power to my Solar Panel array in the Winter Months. Main reason is dual fuel. I like the flexibility. However, the 2 110v receptacles have GFCI curcuits and they do not work properly. Always shutting off. Need to get them replaced with normal duplex outlets.

This is the biggest portable generator I could find. I have tested it and works great and came with everything besides gas. The biggest issues is getting my house wired to accept this much power and unloading it from the shipping pallets because it is very heavy.

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.
