Westinghouse 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

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 110000DFcReasons 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 powerSo 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.

I recently purchased the Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator with Remote Electric Start, and it’s been a fantastic addition to my emergency preparedness setup. Living in an area prone to power outages, I needed a reliable solution to keep my whole house running and ensure my Tesla stays charged when the grid goes down. This generator has delivered on both fronts, and I’m genuinely impressed with its performance.Setting it up was a breeze. It arrived with everything I needed—oil, a funnel, a toolkit, and a remote start key fob—so I had it up and running in no time. The remote electric start is a game-changer; I can fire it up from inside the house without trudging outside in bad weather. Plus, the dual fuel capability (gasoline or propane) gives me flexibility depending on what fuel I have on hand, which is a huge plus during emergencies when gas stations might not be operational.For whole house backup, this generator’s 11,000 peak watts and 9,000 running watts (on gasoline) have been more than enough to power my essentials. I’ve got it hooked up to a transfer switch via the L14-30R outlet, and it effortlessly keeps my refrigerator, lights, Wi-Fi, and even a window AC unit going during outages. The inverter technology ensures clean power with low THD, so I don’t have to worry about sensitive electronics getting fried. It’s not dead silent—around 64 dBA under load—but it’s manageable, especially since I park it outside away from the house.Where this generator really shines for me is charging my Tesla in a pinch. With the 50-amp 14-50R outlet, I can plug in my Tesla Mobile Connector and get a decent charge going. It’s not as fast as a dedicated Level 2 charger, of course, but at about 20-25 miles of range per hour, it’s a lifesaver when I need to keep the car operational during extended outages. I’ve tested it with both gasoline (up to 17 hours on a 7.92-gallon tank) and propane (shorter runtime but cleaner burning), and it handles the load without breaking a sweat.One thing to note: it’s not lightweight at around 187 pounds, but the wheels and handles make it portable enough to move around my property. The CO sensor adds peace of mind, especially when running it near the garage. My only minor gripe is that the fuel efficiency drops a bit under heavy loads—like when charging the Tesla and running the house simultaneously—but that’s to be expected with any generator pushing its limits.Overall, the Westinghouse 11000 Peak Watt Dual Fuel Inverter Generator has been a reliable workhorse for my whole house backup and Tesla charging needs. It’s powerful, versatile, and easy to use, making it a solid investment for anyone looking to stay prepared. I’d recommend it to anyone in a similar boat—especially if you’re balancing household power and EV charging during emergencies.

Purchased the 11000 watt inverter model in January of this year after the threat of a few ice storms here in the Midwest. Followed the break in procedure as described in the manual, running for 5 hours at less than half load varying the load on the generator during those 5 years. I ran the break in exclusively on propane as well. Afterwards, I stored the generator in the garage until 3/14/25 when severe weather came through the area and knocked out power. I rolled the generator out of the garage fired it up, and hooked up to the house, and had all our essentials running with no hiccups from the generator at all.For nearly 4 days, the generator ran flawlessly on both gas and propane keeping our power on at home with enough juice to run our refrigerators, freezers, tv, microwave, sump pump and septic system, AND our electric hot water heater. At the 25 hour mark, I did shut down the generator to take 10 minutes to change the oil which was a simple job to do quickly. And did shut it down overnight when power was not necessarily needed.Overall, during the 4 day span, the generator ran for nearly 60 hours total without any issues. Being dual fuel, having the option to run either propane or gas is amazingly flexible. I ran mostly propane during the outage, but it was nice to be able to switch to gas and keep the generator running while swapping out propane tanks.Generator is super quiet, even under load and seems very fuel efficient as well. Great value for the money and provides clean power for those sensitive circuits in the house!
