Just arrived..unpacked and completed the installation. Including adding the oil connecting the battery and adding fresh gas. The generator will not start on gas mode. it will start using propane. i am bumbed.

This thing is built like a tank. Started up without issue after the tires and oil was added. I've had no issues so far. Make sure you have someone to help you move it cause it's heavy. The tires makes it easy to maneuver around.

I haven't used it to to power the house yet. I will update running my 2.5-ton and 3.5-ton ac in the coming days. This unit is large. It is not hard to move around with the long handles and wheels over flat ground.

I was very pleased with PED ease of ordering. This generator is a beast. It has a lot of power and can run most of your house if not all of it, depending on your house of course. Easy start and easy to move around considering the weight.

No need to buy a cheap cover, cut the box it came in at the lowest point next to the ground as instructed, and the box makes a heavy duty cover with a little trim for the wheels

I bought this after buying a DuroMax duel fuel 13Kw, which would not work on propane. The WGen12000DF worked right out of the box. Very straight forward installation and usage.

I have yet to try it out but from all appearances it looks like a well made machine. I did a lot of research and this generator hit all the marks. I wanted a dual fuel that will power my well, 2 refrigerators, some lights, internet/TV, ect. As others have said, changing the oil will probably be a mess due to the placement of the oil drain plug but we shall see. And putting the wheels on would be kinda tough (due to the wood pallet it comes on) unless you have help lifting it off the pallet or a tractor with a bucket/hitch like I have. It was easy for me. I like the fact that it does come on a wood pallet and my generator arrived at the store in great shape. I have an electrician coming in a week to wire the house panel so I can just plug in the generator on the outside of the house. Overall I am impressed with the workmanship I can see and look forward to never having to worry about another power outage. (last one lasted 10 days)

I bought this unit a month ago. Semi Truck delivery to my home a very pleasant and helpful driver unloaded this unit from his truck with a motorized fork lift/dolly. He delivered it into my garage. Unpacking an extremely well packaged and protected item like my generator was a bit of a challenge however the effort was well worth revealing a fabulous new Westinghouse generator in perfect condition. I went through the stop procedures, minimal, plugged it into my home system and with a touch of a button was generating Low Sine 240 volts to power my entire house including my whole house AC. Only run on propane so far hate to put gas into it yet :=). Works great low noise level 74 Db especially compared to my replaced Honda EB 11000. Thank you Westinghouse.

I first bought a 9500df for a welding trailer rig that I was setting up. However, I discovered that the 9500df puts out 23%THD and the welder would go in safe mode when on high settings. I contacted Westinghouse and found out that I needed the 12000df model that puts out <5% THD and costed twice as much. But it works awesome with my multi processor welder. Also, it has a "low idle" switch that isn't in the manual or shows up in the web site photos. This is a cool feature that is more for job site application so your generator idles down when it's not pulling any power.

Once out of the box, it took about 5-10mins to set it all up. After that, it was ready for work. Nicely put together, this machine has it all. Sturdy wheels, good retractable handlebars. The fact that this generator is powerfull offers the possibility to work with propane and gas was, for me, the selling point. I am not disappointed by my purchase. Will recommend.
