Overview#

The SDMO V550 is a large commercial diesel generator rated at 550 kVA (440 kW) standby, powered by the Volvo Penta TAD1641GE inline-six engine. The 16.1-liter TAD engine is known for its excellent power density, low fuel consumption, and refined operation, making the V550 a strong choice for data centers, large commercial complexes, and industrial facilities where efficiency and reliability are paramount.

SDMO pairs the Volvo Penta engine with a high-performance brushless alternator, advanced digital controller with paralleling and remote monitoring capability, and sound-attenuated enclosure options. The generator produces three-phase power at 277/480V and 60 Hz. Volvo Penta's global service network ensures parts availability and technical support, while SDMO's European-engineered packaging provides a well-integrated, installation-ready power solution.
