Cummins Onan 4HGLBA-8306 QG 4000i 4000W Gasoline RV Generator
The Cummins Onan QG 4000i is engineered specifically for motorhomes, travel trailers, and fifth wheels that require dependable onboard power with exceptionally quiet operation. Producing 4,000 watts of clean inverter power, this gasoline-powered RV generator is designed to handle today's demanding RV electrical systems while providing stable output for sensitive electronics, entertainment systems, and modern appliances. Its compact design and fully enclosed housing make it an excellent choice for OEM installations as well as generator replacements.
Unlike conventional RV generators that operate at a fixed engine speed, the QG 4000i features computer-controlled variable-speed technology that automatically adjusts engine RPM based on electrical demand. This intelligent operation reduces fuel consumption, minimizes vibration, and significantly lowers noise levels compared to traditional generators. Combined with electronic fuel injection (EFI), the returnless fuel system improves reliability, eliminates the need for a fuel return line, and provides dependable starting across a wide range of operating conditions.
Designed with long-term reliability in mind, the QG 4000i incorporates a permanent magnet alternator, integrated inverter, electronic engine management, and comprehensive engine protection systems including low oil level, high oil temperature, and control temperature monitoring. Its fully enclosed, sound-attenuated housing includes a catalytic muffler and USDA Forest Service-approved spark arrestor, allowing it to meet National Park Service sound requirements while delivering smooth, dependable performance wherever your travels take you.
Serviceability is equally impressive thanks to its single-side maintenance access and onboard diagnostic capability. J1939 communication compatibility allows integration with modern RV systems, while Cummins backs the generator with an extensive worldwide dealer network and a 3-year limited warranty for RV applications. Whether you're dry camping, traveling cross-country, or enjoying extended stays off-grid, the Cummins Onan QG 4000i delivers quiet, efficient, and reliable power you can count on.
