Mastervolt Mass Combi Ultra 12/3000-150

The Mastervolt Mass Combi Ultra 12/3000-150 is a professional inverter-charger system designed for reliable power conversion and battery management. This 12V DC to 230V AC unit delivers 3000W of continuous power with a peak capacity of 6000W and provides a sine wave output voltage for compatibility with sensitive electronic devices such as medical equipment and computer systems. The integrated MPPT solar controller achieves up to 30 percent higher energy yield from photovoltaic modules compared to conventional charge controllers, making it particularly efficient for solar applications. With dimensions of 472 x 318 x 178 mm and a weight of 15.3 kg, this compact unit operates in a temperature range of -25 °C to 60 °C. The system includes a 150A intelligent three-stage battery charger with low DC ripple current for extended battery life, capable of charging two separate battery banks simultaneously. The Power Assist function prevents voltage drops and circuit breaker trips even with weak grid connections or small generators. The Active Optima Cooling System allows for up to 50 percent of the charging or inverter capacity to operate without fan operation for quiet nighttime use, with linear fan speed control under high load. Parallel and three-phase configurations support systems up to 35 kW for larger applications. Separate generator and grid inputs with robust switching technology ensure seamless switching between power sources, while dual AC outputs can supply heavy consumers directly from the grid or generator. The unit features galvanic isolation, configurable voltage and frequency parameters, and comprehensive protection against overload, short circuits, and extreme temperatures. It is certified according to CE, E-Mark, ABYC, and RMRS standards with an IP23 protection rating for vertical mounting applications.
