I bought this particular generator over any other, specifically because it has a very low THD %. Beyond that, it has all the power needed for an entire house including two air conditioning units (2 and 2.5 ton) and anything else you can throw at it. I fired it up for the first time, running on propane, and it started up right away, all ports working as they should. This is a beast of a machine and hope to not have to use it, but am confident that if and when the time comes, my family will be just fine!

This thing is a beast...with a kind heart. Unboxing and (minor) assembly was pretty straightforward. Mount the wheels, fill the crankcase with oil (supplied) and connect the battery. She's ready to rock-n-roll! I poured enough gasoline in the tank to make sure it would start and hit the start button. Easy-Peasy! It fired right up and quickly settled at a running speed that would supply power at 60Hz. The display is very nice too. You can verify that it is producing the power you need and check up on running time to make sure you're keeping up on maintenance. I am very pleased with the purchase.

Bought this a week ago in preparation of the south eastern snow and ice storm. Glad I did as the power went out for almost 26 hours and the generator came through for us. The ease of startup with the keyfob made it very easy and kept us out of the weather. Plenty of power and the Westinghouse name made it an easy choice for us. Price was better than comparable tri-fuel models. We are very happy.

Did a ton of research and landed on the WGen11500TFc as striking the right balance of capacity, flexibility (multiple fuel sources) and low THD (prevent damage to sensitive electronics). Admittedly, I have only performed the initial 5-hour break in period, so it’s a small sample size. Time will tell if the unit is durable, but so far so good. While varying some light loads during the break-in period, the unit would barely blip, so you can definitely tell that it has huge capacity. I used propane, and it worked flawlessly. Love the fact that I have flexibility to use propane or gas (also supports natural gas). Kudos to Westinghouse for including all of the essential hoses and hookups for natural gas and propane, along with oil and everything you need to get up and running. The most work you need to do is put the wheels and rubber feet on, add oil, and you’re pretty much ready to go. Battery charger included as well. I have a 50 amp inlet, so this generator will give me close to full available capacity to power my house, including some of the larger power hungry appliances. The low THD was a must-have to avoid damaging my electronics, and I really appreciate that Westinghouse makes a number of portable generators that have THD, relative to other manufacturers. I would add that the generator, while heavy, is fairly easy to move and maneuver with the large wheels and handles. Another reason I preferred this generator was the size was much more manageable vs stepping up into the next tier. I wanted something with large capacity, but didn’t want to deal with manhandling a massive portable generator. If I had one gripe, some of the documentation included with the generator seems to be incorrect. On the included quick start/mechanical guide sheet it says the THD is 23%. I’ve seen other reviewers on Home Depot’s site comment on the THD being incorrect on the included documentation for this generator, so it seems to be a known issue. It just makes it confusing for a customer when the documentation is incorrect.

Living in Houston with a 5 ton A/C unit, I needed a generator large enough to run it. Sure enough, once I installed a soft start on my Trane unit, this generator fires in up with no problem. Added a 50amp receptacle beside main panel and I'm now able to run entire house. And I'm running EXCLUSIVELY on natural gas; the lowest producing fuel. Very happy with purchase.

I will use the generator in emergency cases only. Test runs were satisfying. Generator started instantly and runs stable. Packaging was sufficient to keep the generator save in the box. Quality looks good so far - I unscrewed all mainteance parts to check. Quick start guide is perfect. Answers to my presales questions came quickly from Westinghouse. The description is lacking in my mind of how to handle the battery if the unit is stored in a -relatively- warm garage (Florida), which is defintiely not good for it. So take it out and charge separately? A simple connector between battery and charger should come with the device to enable this. Also maintenance parts should be offered directly online on the web page - would make it easier. What I do not like is to recommend to replace parts during maintenance by a Westinghouse dealer. The generator is too heavy to move it around every 6 months and I will not pay someone to come and do it. The strategy needs to be that the customer can do it himself and the professional only comes into play if really needed. I guess it can be done by the user ... lets wait and see.

Ordered on a Sunday - ir was here Wednesday when I got home from work- she’s a heavy beast- love the dual gfci outlets, both 30 & 50 amp plugs, digital meter for voltage, frequency, hours and service, the output breaker to the outlets is great- it’s a struggle to get out of the box by yourself, but the wheels & feet go in fast and easy.- a few wood blocks makes the process even easier- charged the battery with the included plug in transformer right from the control panel in just a few hours- fired up easily from push start on control panel- the wireless remote same- the pull cord is a bit tougher because this is a pretty big engine- so many awesome pro- style features - I could go on & on. I am only giving it a 4 at this point because I’ve only run it for above 20 minutes and haven’t tested the 30 and 50 amp outputs yet

I purchased the Wgen11500TFC for a total home low THD solution. With recent events, our power utility company has become less reliable in delivering power and went 3 days straight with no power this winter. Time will tell how well this generator holds up but it appears to be solid. Electric and remote start are nice features!

I bought this after Hurricane Helene came through our County in SC and left the county without power. I have a Generac XP8000E that WOULD NOT start the .5 HP Shallow Well Pump. It was supposed to provide 30 amp service but the pump would not start. Running amperage is 8.5. This new pump installed July 2024 is an exact replacement for a pump that was 40+ yrs old and still running, but getting some age on it. Apparently, according to my pump guy I am not the first to experience this problem of a generator not living up to its rating. The fact this runs on Natural Gas was a huge plus as we have NG at our home. Once I get everything hooked up I intend to test it thoroughly. The Generac I can still use for my shop. This unit just looks and feel more well designed and built than the Generac.

I set this up to run on natural gas. At first it ran rough and then wouldn't start at all. After examining the spark plug, it was found to be loose. After tightening, it started right up and ran fine. Overall, this is a great generator. It would have been nice to include some information about the natural gas supply line requirements. I used a 1/2' black pipe line about 50 feet long. I don't know the pressure at my house.
