Engine Performance and Fuel Efficiency

The Volvo TAD1641GE engine running at the heart of the V550C2 IV operates at 1500 RPM and is capable of a maximum standby output of 484 kW at rated speed. With a compression ratio of 16.5 to 1 and an electronic governor holding frequency regulation within plus or minus 0.5 percent, this engine delivers stable and predictable performance. 

Fuel consumption at 100% load measures 102.05 liters per hour, dropping to 75.38 liters per hour at 75% load and 51.02 liters per hour at 50% load, allowing operators to plan fuel logistics with confidence. The cooling system holds 60 liters of coolant and maintains outlet water temperature around 93°C, supported by an 11 kW fan for consistent thermal management.

V550C2 IV Alternator and Electrical Performance

The Kohler AT02450T alternator delivers a continuous nominal rating of 500 kVA at 40°C and a standby rating of 570 kVA at 27°C, with efficiency reaching 94.50 percent at full load. This alternator operates on a direct coupling with a single bearing configuration and no collector rings or brushes, reducing maintenance requirements over the long term. 

Total harmonic distortion stays impressively low, under 1.5 percent at no load and under 2 percent on load, which supports clean power delivery for sensitive electronic equipment. The alternator also demonstrates a strong unbalanced load acceptance ratio of 70 percent, giving it flexibility to handle uneven load distribution across phases.

Control Panel Options for Flexible Operation

The V550C2 IV comes standard with the TELYS control panel, an ergonomic system featuring a large display screen, scroll wheel navigation, and comprehensive monitoring. This panel tracks electrical measurements like voltage, frequency, and amperage alongside engine parameters including oil pressure, coolant temperature, fuel level, and battery voltage. 

It also monitors alarms and faults covering overspeed, failure to start, and voltage min and max conditions. For facilities requiring more advanced power plant management, the optional APM802 offers a 100% touch screen interface with PLC integration, designed for applications in hospitals, data centers, and industrial settings where equipment availability is critical.

Compact Design and Site Flexibility

Built on a mechanically welded chassis with antivibration suspension, the V550C2 IV is designed for straightforward installation and long term durability. The compact open version measures 3,470mm long, 1,500mm wide, and 2,043mm tall, making it a practical fit for sites with limited space. 

For noise sensitive environments, the soundproofed version reduces acoustic pressure to just 76 dB(A) at 1 meter, dropping to 66 dB(A) at 7 meters, all while maintaining the same reliable power output.

Reliable Backup Power for Commercial Applications

Delivered standard with oil and coolant rated to negative 30°C, along with a comprehensive manual for use and installation, the V550C2 IV is ready to provide dependable standby power for commercial and industrial facilities that need flexibility without sacrificing performance.
