Description

For your toughest power needs, the Westinghouse WGen20000c Portable Generator is an ultra-duty generator engineered for strength. It delivers 20,000 running watts and 28,000 peak watts from a heavy-duty 999cc Westinghouse V-twin OHV engine with a cast iron sleeve, and it’s complete with a 3-year limited warranty and lifetime technical support from a nationwide customer service network.

Power and run time: The 17.17 gal. (65 L) tank with built-in fuel gauge delivers up to 11 hours of run time, and up to 17 hours at 25% load. An easy-access start panel puts push-button electric start, a choke knob, and a fuel control valve in one place, so starting is effortless.

Outlets and clean power: Transfer Switch Ready L14-30R and larger 14-50R outlets have the muscle to power major appliances like your air conditioner, refrigerator, and sump pump, plus lights and entertainment centers, all at the same time with a single cord hookup. In total there are four GFCI 120V 5-20R household outlets, two 50A 120/240V 14-50R outlets, two 30A 120/240V L14-30R outlets, and one 30A 120V L5-30R outlet, all with rubber covers for added safety. Outlets produce less than 5% THD, so you can safely charge sensitive electronics directly from the control panel without extra accessories.

Monitoring and safety: The VFT Data Center displays real-time performance information to help you keep up with regular maintenance, including lifetime run hours, volts, and frequency on a digital readout. Automatic low oil and carbon monoxide (CO) shutdown and idle control add protection and efficiency.

Portable and ready to run: A rugged steel frame with lift brackets, reinforced steel handles with quick-release pins, and an included set of heavy-duty wheels get your house, travel trailer, or job site powered in seconds. Oil, a funnel, a setup guide, and a manual come in the box, so you can get started right away.
