About this item

Product details

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 999cc 4-stroke OHV Westinghouse V-Twin engine has a cast-iron sleeve and runs for up to 13 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.

Verified Purchase

This is a huge generator I was in total shock on delivery when they said it was 600 pounds it’s really hard for me to move around because it’s so heavy it should be listed from the notes somewhere on the description. Has a 17 gallon gas tank which has another hundred pounds to this unit when the tank is full overall this is a very nice unit and I do recommend it

Versitile, Mobile and Powerful Platform

This generator is a beast. Surprisingly easy to move around. My driveway has a slight slope and I have no problem rolling up slight incline. As all other reviews have stated, you need a helper or some type of hoist to remove from shipping crate. I fortunately have a mobile hoist in my shop and was able to handle everything on my own. My electrician that installed transfer switch was absolutely impressed with power and mobility. I have a large house that is all electric with two main panels. The dual 50 amp outputs managed the load with the large 4 zone main level A/C and lower level A/C running on a hot humid day. Again, my electrician commented this generator has more power than a lot of permanent whole house systems he installs. The mobility and TriFuel options are a powerful combo.

Great Generator

This is an update to my initial review from a couple days ago. I was able to run the generator today, I have a lockout switch on the panel to my home. I ran the whole house with the exception of A/C and heat as I need to run it for 5 hours before using it with a heavy load. I did not have the whole house powered on but every room in the house had something on, lights, refrigerator and standalone freezer, ceiling fans etc. Ran it for about 1 hour with various loads. Easy to start and move out of the garage. Can't wait to test it in a week or so with the A/C and the heat also.
