Summary
The Westinghouse WGen11500DFc is a dual-fuel generator built around big output numbers, delivering 11,500 running watts and 14,500 starting watts. That combination targets situations where you need strong continuous power while still having enough headroom to handle the extra surge demand that comes when equipment first kicks on.
Because it is dual-fuel, the WGen11500DFc gives you fuel flexibility without changing the core promise of high wattage, making it a straightforward fit for buyers who want one generator that can run on more than one fuel source.
Power & Runtime
With 11,500 running watts and 14,500 starting watts, this generator is designed to support heavy electrical demand and to better tolerate startup surges that can trip lower-capacity units. In practical use, the higher starting wattage matters when loads need a brief burst of extra power to begin operating, while the running wattage is the figure that anchors what it can sustain once everything is up and running.
Noise is rated at 74 dBA, giving you a clear expectation for how loud it will be while operating. Runtime is listed at 19 hours at 25 percent load and 9.5 hours at 50 percent load, which translates into longer stretches between refueling at lighter demand and shorter intervals as you draw more power. Power quality is supported by a total harmonic distortion rating of ≤5%, a concrete spec that speaks to cleaner output for connected devices.
Portability
At 230 lbs, the WGen11500DFc is a substantial machine, and that weight is a real-world factor when you are planning how it will be moved or stored. Its dimensions of 28.9 x 29.6 x 26.9 inches also help set expectations for floor space, whether it is being kept in a garage, transported, or staged for backup power.
Features
Starting flexibility is a highlight here, with a starting system that includes recoil, electric, and remote options. That mix gives you multiple ways to get the generator running, from hands-on pull starting to push-button and remote convenience, which can matter when conditions are inconvenient or when you want faster startup without extra effort.
Day-to-day usability is supported by a fuel gauge for quick at-a-glance checks. The unit lists compliance with EPA and ANSI/PGMA G300-2023, and it includes a spark arrestor, covered outlets, and GFCI outlets, combining safety-minded hardware with practical protection for the receptacles. Automatic voltage regulation (AVR) is included to help manage voltage stability, and the generator is backed by a 3-year warranty.
Recommended Audiences

These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
