Engine and Performance
At the heart of the Cummins 25 kVA generator is the Cummins 4B3.9-G2 engine, a four-cylinder, water-cooled diesel engine with a displacement of 3.9 liters. This naturally aspirated engine operates at 1500 RPM and delivers a prime power output of 20 kW (25 kVA) and a standby rating of 22 kW (27.5 kVA). Its mechanical governor ensures stable performance under varying loads, making it suitable for both continuous and backup power scenarios.
The generator is paired with high-quality alternators such as the Stamford PI144E or Marathon GM-20-4, offering brushless, self-exciting operation with a power factor of 0.8. These alternators are built to withstand harsh conditions and maintain voltage stability, which is critical for sensitive equipment.
Control and Monitoring
Control systems in the Cummins 25 kVA generator are typically provided by DeepSea DSE6210 or SmartGen modules. These digital controllers offer real-time monitoring, automatic start/stop functions, fault diagnostics, and protection features such as over-speed shutdown, high water temperature alerts, and low oil pressure warnings. This ensures safe and efficient operation with minimal human intervention.
Design and Build
The generator is available in both open and silent configurations. The open type measures approximately 1760 mm x 700 mm x 1370 mm and weighs around 750 kg, while the silent type—designed for noise-sensitive environments—comes in a larger enclosure with dimensions of 2450 mm x 980 mm x 1800 mm and weighs about 980 kg.
Cummins applies a rigorous anti-corrosion treatment to its generator sets, including grit blast cleaning and a three-layer protective coating. This ensures long-term durability even in challenging environments. Anti-vibration pads and full torsion analysis further enhance structural integrity and reduce operational wear.
Fuel Efficiency and Environmental Compliance
The generator runs on diesel fuel and consumes approximately 2.42 gallons per hour at full load. It complies with multiple international standards including ISO8528, ISO3046, and EPA regulations for stationary emergency applications3. These certifications reflect Cummins’ commitment to environmental responsibility and product quality.
Applications and Use Cases
The Cummins 25 kVA generator is ideal for:
Residential backup power, ensuring uninterrupted electricity during outages.
Small businesses, such as retail stores, clinics, and restaurants.
Construction sites, where portable and reliable power is essential.
Telecom towers and remote installations, thanks to its compact footprint and dependable performance.
Its versatility is further enhanced by optional accessories like automatic transfer switches (ATS), wireless monitoring kits, cold weather packages, and maintenance kits.
Warranty and Support
Cummins offers a 12-month or 1000-hour warranty, backed by global service networks and spare parts availability. This ensures peace of mind for users who rely on the generator for critical operations.
