Power & Run Time
The Westinghouse iGen12000TFc
The Westinghouse iGen12000TFc delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 9,000W and a peak wattage of 12,000W. When propane-powered, it benefits from 8,100 rated watts and 11,000 peak watts. Its natural gas operation offers 7,200W of rated wattage and 9,800W of starting wattage. Additionally, as the generator is parallel capable (parallel cables (opens in a new tab) not included), it can be linked to a second unit for more power.
Featuring a noise rating of 64 dBA (just slightly more noisy than background music), the inverter generator is equipped with both a manual recoil starter system and a user-friendly and hassle-free electric starter (battery included) for starting. Additionally, the iGen12000TFc features remote starting, offering users increased convenience (key fob included).
In terms of running time, the iGen12000TFc, equipped with a 7.9 gallons fuel tank, is capable of running continuously for up to 19 hours on a full gasoline tank (with fuel consumption estimated at around 0.42 gallons per hour). When utilizing propane, it provides up to 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH) of operation.
The iGen12000TFc produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.
Outlets
The control panel features the upcoming 4 AC outlets:
For RV owners with a 50-amp service, this Westinghouse unit is RV-ready, boasting a 14-50R outlet. In addition, due to the featured twist-lock L14-30R receptacle, the iGen12000TFc is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Westinghouse's ST Switch Outlet
The ST Switch outlet
The iGen12000TFc is what Westinghouse calls Smart Switch Ready. This means that it features a special outlet that allows for an automatic transfer of power in case of a power outage.
To benefit from this feature, you'll need the Westinghouse ST Switch (opens in a new tab), which is not included with the generator.
Simply put, the ST Switch is a cost-effective and versatile portable automatic transfer switch, which can be installed quickly and easily, without an electrician.
Plug the ST Switch into one of your household 120V outlets, plug your appliances to the ST Switch, and connect the iGen12000TFc to the ST Switch via the special outlet and a 120V cord. The generator will automatically turn on when the power goes out, and automatically turn off when the power returns.
Portability
The Westinghouse iGen12000TFc is an inverter generator and features an encased design with the following dimensions: L30.2 x W25.2 x H26.6 in. This design enhances aesthetics and helps minimize noise levels, distinguishing it from conventional, open frame products. The generator has a contemporary design, convenient for recreationally generating power.
Despite its 191 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. Despite the restricted maneuverability, its set of 2 wheels and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.
Features
The iGen12000TFc's control panel
One of the many iGen12000TFc's features is the digital data center, included in its control panel, which conveniently provides information on the lifetime run hours, power output, frequency, voltage and fuel level and thus, helps you monitor its activity and status.
In addition to this info, light indicators on the device will notify you if the generator is ready, the generator is on overload and the oil level is too low.
As far as security is concerned, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during use.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Westinghouse iGen12000TFc is bundled with additional accessories: battery charger, funnel, oil, key fob, propane hose and tool kit.

User Reviews
I’ve had one of those generic little 6000 or so watt gas only generators for years that I never have used. Don’t know if it even came with oil in it. I had a transfer switch set up years ago for the things that were critical (sump pump, furnace, fridge, etc) and some that were just convenience. And never used it.
Summer of 2026 we lost power for about a day and a half. Fortunately for me there was no rain, so the sump wasn’t going. I had two Anker 2000w battery generators in case I needed the sump and used one of them for the fridge. And I realized I was done having to deal with this stuff. Reason I never did the other generator was I didn’t want to have to deal with refilling all the time.
This 12000 TFC was what I ended up on. Arrived quickly, and I began the break in period. I went beyond though, getting break in oil specifically for engines like this, and changed it every 5 hours for the first 15 hours. I also put in a magnetic dipstick to help remove what metal I could.
Once I hit 25 hours I did the final change with the normal synthetic and have the schedule set for maintenance now.
But during the break in period, it was flawless. I had a plumber come and install a gas outlet on my patio so I could run this on natural gas. No effort at all to keep it going this way. And it has ran perfectly, and powered everything I threw at it.
Noise level is really not noticeable inside the house, even with this on the exterior wall of my master bedroom’s bathroom, so it’s close to where I sleep. My white noise machine covers it up but if I were sleeping with this running it would act as its own white noise generator for me, it’s that unobtrusive.
Now looking at upgrading my transfer switch to accommodate more circuit panels. I don’t need A/C so this thing could likely run the whole house, but since I live alone, there’s no need to power some of the rooms, so I’m just going to have an electrician replace my 6 circuit switch with a 10 or 12.
I store mine outside in a special shed so all I have to do is roll it out, connect to the house plug, connect to the gas line, and fire it up. Can’t ask for anything easier than that, other than a big whole house permanent one, and for me there was just no need to spend THAT much money when this gives me all I need and more.
I bought this a month before the blizzard of 2026 and it really came through in the clutch. We lost power for 4 days and it ran perfectly, keeping the lights on and the heat running the whole time. We used propane 20 lb (really 15 lb..) tanks for fuel and got about 6 hrs from each one. A transfer switch is a must to maximize the potential of this generator. Think of it as an investment for your peace of mind. The generator bible gave me the information that I needed to pick the right generator!!
I am having the same issue as John. I just bought the IGEN11000TFC and the wiring configuration is different from the manufacturer’s printed instructions I found to Float the Neutral. On the 50 amp receptacle there is only 1 green/yellow ground wire attached to the green screw. There isn’t a second wire crimped to it. Then there is a white wire on another screw behind it. I did remove the white jumper wire that ran from the control panel to the inverter. Is this all I need to do to float the neutral? I will be connecting this generator to a transfer switch on my home during power outages.
When trying to break the neutral/ground bond, I find my configuration different from the manufacturers. I have a separate single white wire coming from the generator head and it is tied to the ground stud on the front panel. Removing this wire opens the neutral/ground bond. No info from Westinghouse yet if this is the approved method.
Did not find an oil filter or screen as others have described.
Very quiet and no issues so far. Still in break in period.
Update to my earlier review:
Westinghouse has responded to my request for specific information on why my generator (iGEN11000TFc) is different than described in the iGEN11000DFc method of breaking the neutral/ground bond. The reply from Westinghouse:
What the manual specifies
The iGen11000TFc ships with a bonded neutral. The generator’s neutral is factory-connected to
the frame, which also ties into the ground terminal, the metal non-current-carrying parts of the
generator, and the ground terminals of the receptacles
This is done so that devices expecting a neutral-ground connection (tools, RVs, appliances)
function properly.
The schematic confirms the neutral winding is tied to the frame and ground lug at the factory.
Why the extra white wire appears.
On some production runs of the iGen11000TFc, the neutral-to-frame bond is achieved by an added white
jumper wire from the neutral bus to the ground lug. This is equivalent to what the service bulletin shows as
a direct bond, just implemented differently at the factory.
Correct way to open the bond
Removing the white jumper wire at the ground post, then confirming with a meter that neutral and ground
are isolated—matches what is required to convert the unit to a floating neutral. That is the correct way to
break the bond on this model revision.
Documentation
The manual does not explicitly show the removable jumper wire, but it does clearly state the unit is
bonded neutral by design.
Westinghouse’s service bulletin covers the procedure in general, and on this model the removable white
jumper is the functional equivalent of the bond screw illustrated in the bulletin.
