The WEN GN400i is a 4000-watt open-frame inverter generator with a 212cc WEN engine, an RV-ready TT-30R outlet and a CARB-compliant design. It is an inverter unit, so it produces cleaner power than a conventional open-frame generator and runs quieter than most contractor-style models. It suits RV owners, tailgaters and homeowners who want backup power without a heavy, expensive enclosed inverter. Against enclosed inverter rivals it is louder and more exposed to weather, but it is simpler to service and easier to move on its wheels.
