Cummins Onan 2800 Generator 2.8HGLAA-8311

2800 Watts     Inverter Generator     Low Oil Consumption     Quietest Generator Set in Class

The Cummins Onan 2800 Generator 2.8HGLAA-8311 meets CARB and EPA Tier 4 Final and Phase IV standards and specifications required for all motorized recreational vehicle generator sets. For sale in all 50 states. The inverter generator produces high quality power for power-sensitive RV loads. Engine speed varies with the load, reducing fuel use, noise, and vibration. This RV generator is 63% quieter, has 60 percent less vibration than earlier models, and weighs 9% less.

Ideal for truck campers and Class B Motorhomes, the Cummins Onan RV QG 2800 Series Generator starts and runs a 13500 BTU air conditioner with a 600-watt baseload and an additional 300 watts available after the air conditioner starts.

Powered by a 252cc engine rated at 3600 RPM. Uses 0.21 GPH at half load and 0.46 GPH at full load.

CARB 2024 Compliant. For Sale and Use in All 50 States.

Cummins Onan RV Generator Set RV QG 2800

The Cummins Onan 2800 Generator is an inverter generator with a digital voltage regulation, frequency regulation and a single-pole 25-Amp Circuit Breakers. It weighs just 113 pounds and has a compact design of 20 inches x 16.3 inches x 13.4-inches high.

Go RVing in our national parks without worry. The RV Generator Set meets National Park Service sound level requirements of 60 dB(A) or less at 50 feet. Expect less than 65dB at 10 feet away, less than the leading portable inverter generator. Typical installations lower the actual sound level. Vibration isolation ensures the 2800 Watt Generator runs exceptionally smooth and quiet within the full housing and integrated base. Noise is further reduced by the USDA Forest Service approved, fully enclosed, spark-arresting muffler.

The microprocessor controller regulates engine speed between 2445-2900 RPM to meet the power demand. Voltage regulation within ± 10% and frequency regulation within ± 5%—meets ANSI/RVIA requirements. Low Oil Shutdown protects against engine damage and fused DC circuits protect set wiring and remote control. Solid state ignition keeps the Cummins Onan RV Generator Set RV QG 2800 set operating efficiently and economically. Replaceable Fuel and Air Filters.

The RV QG 2800 Series Generator has more oil capacity, eliminating the need to check the oil between scheduled maintenance.

Package Includes the Cummins Onan 2800 Generator Manual.

Cummins 3-year 2000-hour limited warranty which covers all parts and labor excluding routine maintenance.
