Mastervolt CombiMaster 12V - 3000W - 100 Amp (230V)

The Mastervolt CombiMaster 12V - 3000W - 100 Amp (230V) is a professional-grade multi-function inverter-charger designed for marine, RV, and off-grid power applications where reliable DC-to-AC conversion and battery charging are essential. This sophisticated unit serves users who demand simultaneous power inversion and charging capabilities in a single compact device, eliminating the need for separate equipment and reducing installation complexity. Whether you're outfitting a vessel, mobile command center, or remote facility, the CombiMaster delivers the operational flexibility and robust performance that professionals depend on in demanding environments.

Built with Mastervolt's proven inverter-charger architecture, this unit converts 12-volt DC power from batteries into 230-volt AC output at 3000 watts continuous power, while simultaneously managing a 100-amp charging input for battery replenishment from shore power or generator sources. The dual-function design incorporates advanced power management electronics that automatically switch between inverter and charger modes based on AC availability, ensuring seamless power continuity without manual intervention. Its robust construction and thermal management system enable sustained operation in compact spaces while handling the thermal loads associated with high-power conversion—critical for applications where space is limited but power demands are substantial.

Marine technicians, RV system integrators, and industrial off-grid installations benefit most from the CombiMaster's integrated functionality, particularly in applications requiring both emergency backup power and efficient battery charging during transit or docking. The 100-amp charging capability ensures rapid battery bank replenishment when connected to shore power or generator sources, while the 3000-watt inverter output supports high-demand AC loads including refrigeration, power tools, and comfort systems. Installation requires proper 12-volt battery bank sizing and appropriate AC input/output wiring; consult Mastervolt documentation or a qualified marine electrician to ensure your system configuration meets all safety codes and load requirements. At 27.2 lbs and measuring 16 x 10 x 24 inches, it fits within standard equipment locker dimensions while delivering enterprise-level power management capabilities.
