11000 Peak Watt Dual Fuel Portable Inverter Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered, Low THD - Safe for Electronics, Parallel Capable, CO Sensor

Setup was easy once the handle was put into place for better maneuverability. I noticed the supplied funnel looked like it could screw into the oil plug, but it was too small to engage the threads. However, it was easy enough to hold in place while adding the oil. The supplied tools are of high quality and were very useful for attaching the feet and wheel bolts. All-in-all, the unit works flawlessly. It started immediately with the push-button, the remote, and the manual pull-start. It was also very quiet even under a half load. My only concern is a gouge on one of the removable side panels that apparently happened during shipping, but this did not affect my acceptance of the order given that inclement weather was approaching. I am now ready for the storm.

Excellent, very powerful generator with three fuel options: gasoline, natural gas, and propane. I've only tested it with propane from my grill, and it was able to charge my 2022 Tesla Model Y, which can handle up to 32 amps at 220 volts. It easily powers my entire house. It's very quiet, and the inverter system allows me to save energy based on demand. It's much quieter than a conventional generator. My wife was able to start it with the remote control—very easy. I highly recommend it.

Great generator, quiet and powerful.. runs the whole house when needed. This is our second one of this brand, have a smaller one for camping only.

I purchased a 9500DF in October of 2021 after a 3 day blackout earlier that year. The delivery did not go well with the first unit being significantly damaged and the replacement also being damaged (but not as bad and I ended up keeping it). Luckily, I've only had to use that generator about 5 times in the last 3 years, and never for longer than a couple of hours. At the time, friends were getting smaller inverter generators, but as my pool pump needed about 10 amps, I was worried that I wouldn't be able to run much else on a smaller generator. In the last 3 years, inverter generators have come out with more and more power, and when I saw the 11000DFc had almost the same power of the 9500DF, I decided to give it a try. The 11000DFc arrived undamaged. It was very easy to assemble the wheels and feet, and a very similar assembly experience as the 9500DF. I vastly prefer the oil funnel and key fob included with the 9500DF, but that is a minor thing, and I assume that a modern 9500DFc has the same funnel and fob as the current 11000DFc. I have to say that overall, I think I prefer open frame generators. I can attach a piece of plywood to the top, it is easy to secure, and it clears the fill cap of the gas tank. I can't do that with the 11000DFc. It is much easier to weather proof the 9500DF. The 11000DFc started right up on propane. I did not not try is on gasoline because I don't plan to use it and don't have any. Plus I don't feel like trying gasoline and draining it all back out once I do. So I'll take it on faith its good to go if I ever need it, and that it won't leak gasoline all over the place. The 11000DFc is easy to pull start, and once I started trying, I was able to pull start it on propane every time. I've never been able pull start the 9500DF on many attempts. The LP connection to the generator on the 11000DFc seems like an afterthought as it is in an odd place and the regulator is not on the generator like it is the 9500DF. Having the regulator on the tank hose is awkward, and I smelled propane the first time I started it so kept checking the connection of the hose to the generator and the hose to the tank and they were fine. It turned out the be the connection of the hose to the regulator that was very loose. I think just rotating the hose by hand when hooking it up to the tank is enough to loosen this connection. It is something to keep your eye on. The quality of the power is obviously a night and day difference, and if anything, I am much more of an inverter fan now than I was a couple weeks ago. The thing that shocked me is that my pool pump draws 8.4 amps when connected to the 110000DFc, and draws 9.7 amps when connected to the 9500DF. I firgure the extra 1.3 amps are heating up my pool pump motor. I put a scope on the lines and on the 110000DFc, there was a perfect looking sine wave at 242V and 60Hz. On the 9500DF, it was a visibly distorted sine wave (on the top half) at 243V and 63Hz. Nothing I've read about inverter generators vs. AVR generators affected my optinion as much as this one experiment. 8.4 amps vs. 9.7 amps is more of a difference than I thought would have been possible. I guess the distorted sine wave could also be affecting the amp meter. I also tried the Eco Mode switch on the 11000DFc. It clearly idles down significantly in this mode with no load, but with just a 2500 watt load, I couldn't tell if flipping the switch was doing anything. I didn't go higher than that because I'm still in the break in period. Reasons to prefer the 9500DF: - Cost (obviously) - I prefer the open frame - The wheels are larger on the 9500DF and its a bit easier to move over lips and bumps. - I preferred how the LP tank connects to the 9500 generator, plus the hose doesn't need a pressure regulator on it. It is a clearly superior setup compared to the 110000DFc Reasons to prefer the 11000DFc: - It might be a bit quieter. I'm not even sure. They are both loud. - Easier to start - Everything about the power supplied is clearly superior - In theory, it should use less fuel because the engine is not forced to always run at 3600RPM to create 60Hz power So in the end, its all about the power. So if price is not a consideration, I would take the 11000DFc every time just for the better quality power. If Westinghouse offered an open frame inverter more in the physical form factor of the 9500DF, then I would probably prefer the open frame. The noise reduction just isn't worth what I give up in the convenience of the open frame.

UPDATE: I had time today, so I added the oil (which came with the unit), connected the battery and connected the propane tank (using the hose that came with the unit) and started her up! LOVE IT! Much quieter than I expected and I love the idea of using propane over gas since propane can be stored indefinitely and is cleaner. Using the remote start and the Start/Stop push button, the unit started up and ran smoothly and quietly. The control panel is easy to navigate. Set up was easy, all necessary tools and oil, as well as a battery charger came with the unit. As a bonus, because I registered the unit, Westinghouse will be sending a cover! Original: This generator was just delivered the other day. I haven't used it yet. I did unbox it and checked for all parts, then I put the stabilizers, wheels and handle on. I'll connect the battery and get it started in the next week, or so, to test it. I am excited to set it up and test it as I've seen good reviews. I'll be running it on propane; I bought two 40-lb tanks and filled them this week. That said, I am a little disappointed in the scratches on the handle, on both sides at the bend. I was pretty careful in unboxing and setting the parts aside (on the Tonneau cap of my pickup). I had a moving blanket and used the styrofoam packaging to protect the generator when I put it on the sides to install the stabilizers and wheels before putting on the handle. I admit I didn't pay too close attention to the handle when I took it out of the styroofoam packaging and put it on the truck cover but I don't see how anything I did would have cause these scratches. After I put the second wheel on, I tilted the generator back up off the blanket and stryofoam and didn't tilt it again before or after I put the handle on. I cut up the box, gathered the paperwork and turned to get the generator to wheel it to its new spot in the garage and that's when I noted the scratches as the light was hitting the handle from a different angle. I wish I had inspected the handle more closely as I walked it from the unboxing area to my truck so I could confirm it arrived that way. I did check the oil and saw that there was some on the dipstick, which I expect from manufacturer testing. It won't affect the performance and, I guess, I'll get some paint to cover the scratches. It may seem petty, but I bought something new and expected it to be without these scratches.

Nice generator. Easy initial set-up. Haven't lost power yet, but seems to run fine on gasoline.

Works flawlessly and has excellent clean power output. Was vital for that with all of my UPS units in the home, or they would have failed with a standard generator. Unit is super quiet and easy to maintain as well.
