I received the wgen12000df in a relatively short time after ordering. After initial setup, this thing fired right up. It had no problem powering everything I threw at it (all house led house lights, fridge, sump pump, fans, tv's, 3 ton ac unit, ect). I very impressed with how the generator maintains the 60 hz at various loads.

After our loss of power generation due to extended freezing weather in February 2021, I knew I was going to buy a solution. It took a couple of months to evaluate needs and choices, then another month to compare retail prices and availability. I was happy to find this U.S.-engineered Westinghouse packed with features and exactly what I need. An electrician installed a 200 amp, double throw transfer switch and 50 amp receptacle for this generator. This will allow me to switch over to generator power and add load incrementally. It handled my largest power users without a quiver. I am very happy with it.

I'll be ready for the next extended power outage with the WGen14500tfc! I piped it up to natural gas and it started on the first attempt. After the 5-hour break-in period, I tested it to see if it would run my entire house and it did easily. This includes my 5-ton central A/C (with soft start), but I didn't run my electric oven or dryer, which I wouldn't do in a power outage anyway. Very happy with the purchase!

Only 3 stars at present until Westinghouse responds. And, no recommendation until Westinghouse responds. Assembly instruction are clear, and assembly and initial setup went pretty well, but there are a couple of issues. Once the wheels are on, the battery cannot be removed to connect the cables, so off came the wheel. Also, the dip stick is awkward to use because on a instruction plate above the stick's grip. Still, minor issues. I put in 5 gallons of 87 octane unleaded gas (<10% alcohol). The generator started immediately, with no issues. I let is run for an hour without any load connected. I do have a concern about the engine and generator stability. The engine RPM had a slight instability which sounded like a very, very, slight misfire, but no popping from the exhaust. Voltage and Frequency shown on the set's display was 240 +/- 1V, and 59.6 - 59.9 HZ. I did not connect it to my house, choosing to wait until the following day. Following day: The set powered up immediately, which was nice, but I noticed that the display was now showing an unstable frequency 59.3 - 59.8 HZ (why lower than yesterday?). Voltage was 240/241 V.. Stopped and restarted the set, but no difference. I had intended connecting to the house though the 50A inlet and interlock, but, before doing so, I decided to first look at the voltage waveform with an oscilloscope and meter. I was surprised to see that the intended sine wave looked more like a triangular wave. I don't know if this is the correct output from the Westinghouse generators, so I will look forward to Westinghouse's response. Attached are two video's showing the generators output vs my utility supply. For a valid comparison, the same test setup was used. Couldn't attach the videos because it seems that Westinghouse only accepts YouTube videos, so all I can show is a photo of the WGEN's output waveform.

We received red this generator about a week ago The assembly was straight forward with no difficulties. The unit fired right up on a 20lb propane tank. Only tested a drop light so far to confirm there is an output. The generator is loud but not near what I was expecting. We are getting larger tanks installed and will complete the break in at that time.

Just got it yesterday, fired it up today .. started immediately… have not ran a load yet. But will, after the break-in period… unfortunately I have to run it for at lease 5 hours before I can put a substantial load on it.. but will have that done in a few days.. no problem

I spent quite a bit of time researching portable generators and found this unit to be the most feature rich of any other in it's class. What sold me was the power combined with the <5%thd. Throw in things like remote start, duel fuel, smart idle and transfer switch ready and I couldn't find another unit that matched up.

This generator was so much easier to use than I thought. It also powered much more than I expected. We have a 5,000 sq foot house with two large central air conditioning units, as well as a wood workshop. Short of running the shop machinery, this generator powered all of it! I'd recommend this generator to anyone who needs a serious emergency power source.

This generator is great! It had exactly what I needed. It can run both 50 Amp at the same time. Wish it had better fuel efficiency but it can make the power. There is a power saving mode in it which I like. It’s not as quiet as you would like but that feature help when you turn it on. If you are getting it on a palette, make sure you can get off with out hurting yourself.

I bought this generator during the emergency preparedness tax free weekend. I had a Generac 6500 portable generator but needed higher output and the flexibility to run off of natural gas. This is a great generator with low THD that integrates perfectly into my home electrical system!
