Description
The Mass Combi Ultra 12/3000-150 is a powerful, complete and versatile inverter/charger for professional and semi-professional use. It combines a 3000 W true sine wave inverter with an intelligent 3-step+ 150A battery charger and adds an integrated MPPT solar charge regulator, so a single unit can draw on shore power, generator, battery and solar. For larger installations up to 35 kW it can be operated in parallel or 3-phase configurations.
The latest inverter technology gives a uniquely low standby draw, while an ultra-fast Digital Signal Processor switches seamlessly between every available energy source. Power Assist prevents power dips and tripped fuses even on a weak shore line or small generator, and the Active Optima Cooling concept keeps the unit quiet by holding the fan still until extra capacity is required.
Dual AC inputs and outputs let the generator and mains connections each be optimised, and integrated MasterBus communication ties the Combi into a wider Mastervolt monitoring and control system.
