Nothing But Problems

We bought this generator to run a food truck. It starts great, but turns off on its own every 5-20 minutes. We have done all of the troubleshooting and nothing helps. It is very frustrating. Also, it is very loud. The power is great, but that doesn't help much if it won't stay running.

Big enough for the house

This was the largest portable generator I could find (12,000/15,000 running/peak watts) to run my house during power outtages. It will power everything except my 3-ton A/C and the wife's hair dryer. : ) Everything I looked at that was larger was non-portable (and a lot more expensive). Pros: * Extra long handles and large wheels makes for easy moving/positioning. * Handles fold down for efficient storage. * Remote push-button starter really helps the Mrs. get it going when I'm away. * Transfer-switch ready plug made it super easy to connect to house transfer box. * Cost of generator vs. power produced is hard to beat. * 3-Year warranty out of the box. Cons: * It's loud, especially when running in the early evenings. I wish there was an option to install a quieter muffler and/or longer exhaust pipe to direct the noise up and out. * Made in China. We'll see how well it stands up over time.

Startup & Run didn't go well

I purchased March 18 2022, received March 31 2022, stored in garage until June 10 2022 for initial startup & run...followed all startup procedures. Then ran under moderate load for about 5-10 mins then it shut down. Ran again in an hour or so w/o any load and it shut down within 5-10 mins. I then called customer service.

Absolute Monster

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.

This generator runs my entire house!

After two long power outages this year it was time to invest in a whole house generator. I did my homework and ultimately decided on the WGen12000. The generator was delivered very well packaged secured on a solid pallet. Assembling the generator was fast and simple. Note: Hooking up battery required removing it from its perch. Assembling the necessary components and filling up the oil took a half hour. The included battery came fully charged and the generator started on the second attempt. Since that first starting it fires up immediately. It is loud. It is heavy! It is easy to move, however. The wheels are stout and the collapsible handles enable moving the generator pretty easy. My house is large and located well off the beaten path. The submersable well and a/c system operate just fine while being powered by this WGen12000. Because it is portable, I'm comfortable knowing it's protected from the environment when I'm not operating it. I've operated it for several hours (over 22) and have used only 13.5 gallons of fuel. The digital readout panel is a must. So far I'm very happy!

Nice Generator

Bought the unit in April 2022. Arrived well packaged on a small wood pallet. Easy to open and remove using provide moving handles. Setup and operating instructions were easy to follow. All parts, lube oil, accessories were provided. Tooe less than 30 minutes for assembly and readying for startup. Battery needed some charging before use, with provided charger. No issues. Startup was easy and immediate with FOB or start button. All readings were a go. Haven't yet used it but all appears in order. Nice generator. Control panel well laid out and functional. Would recommend to others based on what I've seen thus far.

No Sound!!!!!

Hopefully, I will change my mind soon. As of now, my brand-new WGen20000 will not start. Not even a sound. Followed the starting directions. Battery charged, plenty of fuel and oil. Pushed the button with no sound. I've got a big job that requires this size machine, and I will not be ready because of this issue. Received the machine with the box already open with parts missing. Right now, it just seems like a bad expensive purchase. Does anybody have any suggestions?

WORKS GREAT!

I bought this for whole home backup. I had already wired in the plugin and transfer switch. Setup of the generator was easy. I added the oil and gas as described and then I had to charge the battery before it would start. After running it for the break in period I hooked it up to the house and it ran everything Including my pool and 4 ton A/C system. I ran the whole house for 30 minutes then let it cool down. I will write more after the first power outage.

Works but Engine shuts off after 5-10 minutes of o

Bought this as a backup generator for my house and it performs as it should under load but the engine shuts down after 5-10 minutes of operation. Doesn't trip any breakers and starts right back up after shutting down. Being brand new this should not happen for what these cost.
