• EPA Compliant: Export Only

This generator arrives delivered with oil, coolant rated to negative 30°C, and a complete manual for use and installation, making it ready for deployment across a wide range of climates. Whether configured for 400/230V, 415/240V, or one of five additional voltage options, the V500C2 IV brings dependable Volvo power to facilities that need proven reliability.

Volvo Engine Performance in the V500C2 IV

Powering this generator is the Volvo TAD1345GE, a 6-cylinder, inline, turbocharged engine with air to air DC cooling, displacing 12.78 cubic inches and running at 1500 RPM. The engine reaches a maximum standby power of 441 kW at rated speed, giving this unit solid headroom above its nameplate rating. 

Fuel consumption at 100% load comes in at 91.8 L/hr, dropping to 69.2 L/hr at 75% and 46.6 L/hr at 50%, figures that support predictable operating costs across varying load profiles. Heat rejection totals 303 kW to exhaust and 160 kW to coolant, with emissions data showing particulate matter at 0.058 g/kW.h and carbon monoxide at 0.42 g/kW.h, relevant figures for facilities tracking environmental compliance.

Voltage Flexibility Across Seven Configurations

The V500C2 IV stands out for its voltage flexibility, offering seven distinct configurations including 220 TRI, 415/240V, 400/230V, 380/220V, 200/115V, 240 TRI, and 230 TRI, all delivering the same 400 kW / 500 kVA standby rating and 364 kW / 455 kVA prime rating. Standby amperage varies by configuration, ranging from 696 amps at 415/240V up to 1443 amps at 200/115V. 

Prime power is available for unlimited annual operating hours in variable load applications, while standby power supports emergency use with no overload permitted, both in accordance with ISO 8528-1. This range of voltage options makes the unit adaptable to installations across different regions and electrical standards without requiring a different base model.

AT02070T Alternator Performance and Electrical Characteristics

The AT02070T alternator delivers a continuous nominal rating of 455 kVA at 40°C and a standby rating of 500 kVA at 27°C, with efficiency reaching 93.80% at full load. Built with Class H insulation and a direct coupled single bearing design, the alternator maintains total harmonic distortion below 1.5% at no load and below 2% under load, figures that matter for sensitive electronic equipment sharing the electrical system. 

The brushless, collarless technology reduces maintenance needs, while a notably high unbalanced load acceptance ratio of 70% gives this alternator strong tolerance for uneven load distribution across phases, a useful trait in facilities with variable equipment demands.

Enclosure Options and Control Systems for the V500C2 IV

Buyers can choose between a compact open version and the M228 soundproofed enclosure, which brings acoustic pressure to 78 dB(A) at one meter while adding weather protection. 

A CN09 compliant containment option meeting the 2000-14-CE standard is also available, along with an M228 DW containment version featuring an expanded 1368 liter fuel tank for extended runtime. 

Control comes standard through the ergonomic TELYS panel, offering full electrical and engine monitoring with USB and PC connectivity, while the APM802 touchscreen system is available as an upgrade for facilities requiring power plant level management and coupling capability.
