The Mass Combi Ultra series comprises several models, varying from 3000 W to 3500 W. For higher capacities up to 35 kW the Combi Ultra can be used in parallel or 3-phase configurations. An efficient and integrated solar charge regulator helps make the most of your solar panels.
The Mass Combi Ultra is equipped with the latest technologies. The new ‘V6’ inverter technology ensures a uniquely low stand-by use, while an ultra-fast Digital Signal Processor guarantees seamless switching between all available energy sources. Power Assist prevents power dips and failures, even with a weak electricity connection or small generator. Moreover, all Mass Combi Ultra models are equipped with MasterBus.
For professional applications, Mastervolt offers a ‘Pro’ model, featuring all Ultra functions, but without the solar input and secondary battery charger.
Higher yield from solar energy
At Mastervolt we used our knowledge gained in the grid connected solar sector to make a super-efficient built-in MPPT solar charge regulator. Compared to most solar charge regulators on the market, the MPPT offers up to 30 % more yield from solar panels. The solar panels power ‘hidden’ consumers and keep your batteries in optimal condition.
The Combi Ultra can provide up to 50 % of the charging current or inverter capacity without fan cooling. This is perfect for night-time operation; if little power is consumed, the fan stops turning and goes silent. When maximum capacity is required, or the ambient temperature is very high, the Active Optima Cooling concept regulates the fan speed in a linear way, ensuring that it never spins too fast or makes any unnecessary ticking noises.
The inverter is quiet, clean and efficient, and offers the full capacity even in extreme ambient temperatures. Pure sine wave energy and a peak capacity of 200 % guarantee a problem-free start, even for the heaviest loads.
Optimal battery use
The powerful battery charger simultaneously charges two battery banks and provides a full charge current in ambient temperatures up to 40 °C. Meticulous load properties and a low ripple current guarantee a long battery life. The 24 V model can combine 12 V and 24 V battery banks.
