Engine and Fuel System Performance

At the heart of this liquid-cooled standby generator is a 5.9-liter turbocharged and aftercooled inline 6-cylinder engine with a cast-iron block. This heavy-duty design ensures longevity and performance under sustained loads.

Fuel Options

• Natural Gas standby generator configuration

• Propane standby generator configuration

• Field-selectable fuel type

Fuel Consumption (Full Load)

• Natural Gas: 1083.5 cubic feet per hour

• Propane: 11.56 gallons per hour

The 12-volt starting system with 850-amp capacity ensures reliable starts even at 0°F. Combined with extreme cold-weather capability down to -40°F, this generator performs where many competitors fail.

For facilities in colder regions, this feature alone significantly reduces operational risk. Cummins RS80 Quiet Connect 80kW 120/208V 3 Phase Generator

PowerCommand 1.1 Control System

The integrated PowerCommand 1.1 control is one of the most advanced features of this 3 phase standby generator.

What It Provides:

• Automatic start and stop

• Digital output metering

• Fault detection and auto shutdown

• Programmable exercise cycles

• NFPA 110 Level 1 capable configuration

Voltage is regulated to ±1%, and frequency is controlled to 0.25% at 60 Hz. For data centers, manufacturing lines, medical facilities, and commercial refrigeration, this precision protects sensitive electronics and motors.

The flexible exercise mode allows scheduling runs for as little as two minutes every six months. This reduces unnecessary fuel consumption while keeping the engine ready.

---

Industrial-Grade Enclosure and Structural Strength

The RS80 features a Sound Level 1 advanced aluminum enclosure with a durable powder coat finish.

Strukturelle Vorteile:

• Wind resistance up to 180 MPH (ASCE 7-10 compliant)

• Corrosion-resistant aluminum construction

• Service doors for simplified maintenance

• 73 dBA noise level

For coastal or hurricane-prone areas, this structural rating is critical. Many standard commercial generators do not offer this level of wind-load certification.
