Installed wheels, oil, & connected battery... Unit fired right off. Used continuously for two days (on propane), not one issue. Ran A/C, two refrigerators, computer, lights... Best investment I've made in a long time. Only drawback is it's made in Vietnam, not American made.

Just received this but have already used it on a job site. I have it powering two 20 in concrete grinders, two dust collectors and a 5in hand grinder and vac. No hiccups at all. It's pretty large and heavy but moves around ease with the large tires .So far I'm very impressed.

Had this delivered and it worked great, but developed a small noise in the starter. Emailed Customer Service and they were extremely prompt addressing this issue, and sent me out a new starter no-charge. Now there's no starter noise, and the generator runs like a freight train!

After getting a quote for a back-up generator, this beast fits the bill. It will run my entire 2500 sq ft house including AC with no difficulty and was a 1/4 the cost. Giving up the connection to the gas line and the automatic transfer switch, but saving a lot of money

Powerful, efficient, and quiet! After extensive research, I found the W12000DF Generator is the most efficient on fuel in the class of its size... AND it's the best bang for your buck. Along with a great warranty, what's to hesitate? It provides more runtime on a tank of gas than other comparable unit I looked at. We also heat our home with propane, so this spring, I'm planning on running a line to the rear patio so there will plenty of fuel for any extended outage situation. There are plenty of outlets. The weatherproof outlet covers are a great feature, snap in place. We live in a rural area and the electric goes out every season. This past winter it was out for 5 days...frustrating as it is, but finally we can run our entire home on this plant alone...we have 2 separate electric entrances, and it runs both. Before, on our little generator, we could only run on 110; a few lights and no appliances; now we can run everything, including the electric range, water heater, well pumps and even my small welder (if I need it). For a portable unit, this Gen packs a great punch. It's heavy, but once in place, it'll just do its thing. I love the push button start and the remote start FOB...super easy; no more pulling recoil cords!...especially in freezing weather! If you use the remote start, the switch on the Gen will have to be "on", which means it will put a continual drain on the battery but just remember to turn it off when in storage. Comes with its own charger, simple to use. Battery is a little difficult to attach but it's kept out of the way and once it's connected, forget about it. The charger port is on the front of the panel so it's not a problem to charge it. I would suggest purchasing a transfer switch to compliment your unit. I got a 50 amp outside connector box with a twist-lock cord and hardwired the box directly into our circuit panels. Works great!

I purchased this based on industry rating and am not disappointed! The output is great, having two 50amp outlets, pushing 12K each. My home has two AC units, so I installed Reliance 10 circuit transfer switch and the TRB0606C. The 10 circuit runs the smaller AC unit and eight other breakers, the TRB runs the larger AC unit and two other breakers. Love it and I can take it with me.

Upgraded our older Westinghouse generator to this one. This has enough power to run most essential circuits in our house plus a few more. It's more expensive than other brands but I trust Westinghouse and it was one of the only ones that had less than 5% THD so we don't fry our household appliances anymore. Overall very happy and should last for years to come

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?

The generator works great. Using with a transfer switch and it produces all the power we need. I would recommend this generator for anyone wanting to power their home during a power outage. We endure Public Safety Power Shutoff events which can mean no power for several days to a week. Deducted a star because it was extremely difficult to get technical assistance. Finally, got some help after 10 business days and it turns out the problem I thought I had is normal. I thought I had an issue with low voltage and RPMs but it turns out it the Smart Idle feature--wish was better explained in the manual. Guess I was not the only one with concerns as I was told there is going to a switch to turn off the Smart Idle feature based on feedback.

That 74dB in the specs is at idle, producing no power. Running, it checks out at 79-80dB at 27ft even at no load. Same as my 20yo Generac but feels louder. But it runs great on propane and produces clean power, a steady 120VAC at 60Hz. Except at idle, where the voltage runs as high as 149V on each leg and Hz up to 75. I'll just make sure to NEVER connect it to any load with it set to idle. Since it is about the only genset of this size that offer clean power AND runs on LPG, I'll live with the flaws.
