Cummins Onan 2500i LP Generator

The new Onan 2500i LP Generator uses inverter technology for cleaner power while using less fuel and producing less noise than earlier models. The new Cummins Onan RV QG 2500i LP powered RV generator replaces older models like Onan Microlite 2500 and the 2.5HGJBB-1121. New benefits include no daily oil check between maintenance with a 40 percent higher oil capacity plus a new permanent magnet alternator (PMA). This 2500 running watt propane fueled generator is US EPA and California CARB emissions compliant.

Operating Characteristics 

Inverter technology allows the generator engine to run at variable speeds depending on the load. Higher loads increase the speed while lower power use decreases the engine speed to save fuel and reduce noise. The catalytic muffler within the enclosure further reduces noise. A three-point mounting system isolates vibration and the enclosure for quieter, smoother operation. Noise output ranges from below 59 dBA at no load to 65 dBA at full load* making the Onan 2500i LP Generator the quietest its class.

Features & Benefits

Computer controlled operation matches the load demand to the engine speed, minimizing the 2500 noise level and vibration. Meets National Park Service noise requirements and has a USDA Forest Service approved no-maintenance spark arrestor.

The PMA has no bearings to wear out and no brushes to replace. It powers the inverter for a pure sine wave output and the best possible power quality. Overload control prevents unnecessary circuit breaker tripping when the air conditioner starts.

Fully Tested for RV Applications in Cummins owned RVs in extreme conditions including high humidity, salt spray, heavy dust and temperatures between -20 F and 120 F both starting and running.

The Cummins 3-Year Warranty applies to RV generator sets used in RV applications.
