  • Automatic Home Backup Made Portable: Pair with the Westinghouse WATS200 Automatic Transfer Switch for automatic backup power. This revolutionary, first-of-its-kind technology combines standby convenience with portable versatility. Exclusive to Westinghouse. Switch sold separately.
  • Built for Longer Engine Life: The powerful 999cc engine features full-pressure lubrication that delivers oil to critical components, reducing friction and wear. An automotive-style oil filter captures abrasive particles and contaminants for cleaner oil and long-lasting engine performance.
  • Power for sensitive electronics: Less than 5% THD delivers cleaner power for phones, computers and TVs. Copper windings help it run cooler and last longer. Push-button and remote start simplify startup; a 17.2-gallon gas tank supports extended operation.
  • Fuel flexibility: Choose gasoline, propane or natural gas. Delivers 20,000 running/28,000 peak watts on gasoline. 50A and 30A outlets pair well with an interlock kit, manual transfer switch or Westinghouse WATS200 ATS system for home backup (sold separately).

Description

The Westinghouse WGen20000TFc tri fuel portable generator with CO sensor produces up to 28,000 peak watts and 20,000 running watts and runs on gasoline, propane, or natural gas. The heavy-duty 999 cc 4-stroke OHV Westinghouse V-Twin engine has a cast-iron sleeve and runs for up to 15 hours at 25% load on a 17.2-gallon gas tank, keeping you powered all day or night with a built-in fuel gauge, automatic low-oil shutdown, and GFCI outlets. Push button electric start and a remote start key fob makes starting easy. At less than 5% THD, you can safely power electronics like computers, phones and TVs. Copper windings help the unit produce cleaner power, run cooler and last longer. There are two 14-50R 50A outlets and two L14-30R 30A outlets. All are transfer-switch and interlock kit ready so they can power major appliances like air conditioners, refrigerators, sump pumps, as well as lights and entertainment centers at once with a single cord hookup. It also has a 120V L5-30R 30A outlet. Our exclusive 125A 240V AC terminal block lets a licensed electrician hardwire the generator directly to your home for full power delivery. A VFT data center shows voltage output, frequency, and lifetime hours for real-time information and maintenance alerts. Easily portable with never-flat wheels, handles, and lift bracket, it’ll have your house, travel trailer or jobsite powered in seconds. Backed by a 3-year limited warranty, lifetime tech support, and our Westinghouse Nationwide Service Network.

This Generator is Massive!!!
Style: 28000 Watts - Tri Fuel - CO Sensor
Man, this is one HEAVY unit. It comes to you via truck freight, so keep that in mind. This generator is a beast!! Had electrician hook up the outside outlet box and interlock and hookup was a breeze. Electrician says this will power my whole electric heat house. The 3 different fuel sources I can use is a plus. Have plenty of help unpacking and putting wheels on as again, this generator is HEAVY. So far all around great purchase. Bought 50A outlet box & cord with it. Glad I did. ... show more

Perfect midsize mobile generator
Style: 28000 Watts - Tri Fuel - CO Sensor
This generator is definitely a beast. I had a front loader so it was easy unpack and set up. I have a 7000 square-foot house. It will power two of my 4 ton air conditioners along with pretty much everything else in the house. Amazing. Definitely a must for some one that doesn’t want a fixed in place generator and the cost of one. ... show more

Bad A** generator!!
Style: 28000 Watts - Tri Fuel - CO Sensor
This thing is a monster!! I've got it running off natural gas, and it runs my whole house, in including my pool pump!! Definitely worth the money. All the parts for it are available and not expensive, but the parts are cheaper from Westinghouse. This generator also includes a battery maintainer

Beautiful Machine but it won’t run under load…horrible product support
Style: 28000 Watts - Tri Fuel - CO Sensor
EXTREMELY disappointed in this product and the support received. Received the generator on 7/23/26. Followed set up and break in instructions to the letter. The generator won’t run except for a minute or two under load…it just cuts off. Placed two calls to the support number, place a ticket, and responded to two emails. Each time I have to repeat what is happening. It’s like they haven’t even documented anything they’ve been told. I’ve asked for a replacement but nothing but crickets. Right now I have a 600 pound pice of scrap metal just in time for peak storm season. Not so much as a call from them. Horrible. ... show more
