I originally wanted a whole house generator in case of a hurricane. I also wanted a generator that I could take with me when I downsize and this one fit the bill. A "standby "generator would have to be sold with the house no money added to house value. This portable generator is big enough to power my current house and mobile so that when we downsize it will be able to power any smaller size house and have room to spare.

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.

I bought this generator as a backup for a possible power outage at our home. The generator seems very solidly built and should serve us well. I was particularly impressed by the dual fuel functionality, which will provide multiple options for use of either gas or propane. The only thing that I was surprised about was that the unit did not come with pneumatic tires which I had expected because of its heavy weight. My only hope is that the plastic tire/wheel (never-flat) combination will provide good service without cracking and breaking. Only time will tell about that feature.

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.

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.

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 purchase this last week and received today. Everything came in great condition - shipper was 5 stars as well. Assembly was easy. Hooking up the negative cable on the battery took a few tools, but item came with some tools as well. The instructions says something about needing two persons, this has to do with getting the generator off the wooden crate it was sitting on. Well one person can do it, my solution was with small ramp from some scrap wood, probable the most difficult of the assy. Started up 1st try on gasoline per instructions, same with fob. I still have to test with propane (my propane 5 gal tank had rusted on to the past cable - soaking with WD-40). I will be wiring to house in couple weeks ahead with licensed electrician. But so far am very delighted.

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.

I bought this on 8/26/2021, took about 3 weeks to arrive but well worth the wait. It came with everything needed to start it up except the fuel. I started it up today and will allow it to break in so I do not want to put too much of a load on it but will vary the load up to 4000 Watts for the first couple hours. I expected it to be much louder than it actually is, thank you for everyone that reviewed it and said it was very loud. I was pleasantly surprised that I could barely hear in inside the house. I have only ran it for about 30 minutes so far and time will tell but I'm super excited to have it.

This portable generator is everything the description says it is. It runs our 2000sq ft home with no problem. It doesn't drag when our air conditioner kicks on, it's tough. It will definitely serve it's purpose during hurricane season in SWLA!! Plenty of outlets for extra plug-ins. It is surprisingly quiet for as big as it is. We have no complaints and are super happy with our purchase. Pretty sure we will be putting it to the ultimate test during hurricane season. I have no worries, it's going to provide the power to my home and then some. Thank you Westinghouse!!
