Engineered for Reliable 36kW Standby Generator Performance

At the heart of this system is a 2.4-liter turbocharged and aftercooled Cummins engine operating at 1800 RPM. Lower engine speed reduces wear, increases longevity, and minimizes sound output compared to higher-RPM alternatives.

Key engine specifications:

• 2.4L inline 4-cylinder engine

• 1800 RPM operation

• Liquid-cooled system

• Cast iron block construction

• Automatic start capability

• Low oil shutdown protection

Unlike many air-cooled units in this power class, this liquid-cooled 1800 RPM generator is engineered for continuous-duty durability. It performs exceptionally under load, especially during extended outages.

Fuel flexibility is another advantage. The unit operates on:

• Natural gas standby generator configuration

• Propane standby generator configuration

Fuel selection is field-configurable during installation, offering flexibility depending on your infrastructure.

Advanced PowerCommand 1.1 Control System

The integrated PowerCommand 1.1 control system sets the Cummins Quiet Connect series apart from conventional standby generators.

This controller provides:

• 128 x 64 backlit LED display

• Remote start/stop capability

• Automatic fault detection

• Alarm and status display

• Auto shutdown protection

• ±1% voltage regulation

• NFPA 110 Level 1 capability (with accessories)

The PowerCommand 1.1 control continuously monitors generator health. If an issue arises, it logs and displays diagnostic information immediately, reducing downtime and simplifying maintenance.

For property owners managing multiple systems, this level of integration ensures full operational visibility.

Built for Extreme Environmental Conditions

This 36kW standby generator is designed to operate in harsh climates.

Cold weather capabilities:

• Starts in temperatures down to -40°F

• Factory-installed coolant heater

• Crankcase vent heater

For property owners in cold regions, these features eliminate common winter startup failures.

It also meets major compliance standards:

• UL-2200 certified generator

• EPA emissions compliant (Emergency Stationary 40CFR60)

• IBC Seismic compliant

• NFPA 110 compatible (with required accessories)

Note: Not for sale in California due to emissions regulations.

Practical Installation & Setup Strategy

To maximize performance, follow these expert recommendations:

1. Install on a prepared mounting pad with proper drainage.

2. Pair with a compatible automatic transfer switch:

   • Cummins RA

   • Cummins RSS

   • Cummins OTEC

3. Size fuel supply lines correctly based on consumption:

   • NG Full Load: 472.3 CFH

   • LP Full Load: 5.1 GPH

4. Schedule regular exercise cycles using flexible exercise mode (as low as 2 minutes every 6 months).

Correct installation ensures NFPA compliance and extends system life.

Expert Insight: When 36kW Is the Right Choice

From a power management standpoint, a 36kW generator is ideal when:

• Whole-home backup is required

• HVAC load exceeds 5 tons

• Multiple appliances run simultaneously

• Small commercial refrigeration must remain active

In real-world installations, this size is frequently selected for:

• Large single-family homes (4,000+ sq ft)

• Medical clinics

• Restaurants

• Professional offices

Compared to smaller air-cooled units, the liquid-cooled 1800 RPM design significantly improves longevity during long outages.

If your load exceeds 150 amps or requires three-phase power, upgrading to the 150kW class such as the Cummins RS150 is recommended.

---

Maintenance & Longevity Strategy

To protect your investment:

• Inspect oil and coolant every 6 months

• Run monthly exercise cycles

• Replace filters annually or per service schedule

• Maintain battery (12V, 550 CCA minimum)

The brushless alternator and cast iron engine block are engineered for extended service life.

Cummins backs this unit with a 2-Year Limited Warranty, with extended coverage available up to 10 years.
