Mastervolt Mass Combi Ultra combination unit

Mass Combi Ultra & Pro

The Mass Combi Ultra is equipped with state-of-the-art technology. New inverter technology ensures exceptionally low standby power consumption, while an ultra-fast digital signal processor guarantees seamless switching between all available energy sources. Power Assist prevents power dips and outages in the event of a weak power supply. Furthermore, all Mass Combi Ultra models feature a master bus. An integrated MPPT solar charge controller ensures optimal energy yield from your solar panels.

The Mass Combi Ultra provides up to 50% of the charging current or inverter capacity without fan cooling. This makes it ideal for nighttime operation. When power consumption is low, the fan switches off. If maximum capacity is required or the ambient temperature rises, the fan speed is linearly regulated, ensuring it never spins too fast or generates unnecessary noise.

The Mass Combi Ultra's design also allows for parallel or three-phase configurations for larger applications up to 35 kW. For larger systems, an external transfer switch is required. The Mass Combi Ultra features two separate AC inputs, each tailored to the specific characteristics of the power source (generators or shore power). Thanks to its extremely fast control, flickering lights and the unintentional shutdown of sensitive equipment are prevented.

Pro models
For professional applications, Mastervolt offers a 'Pro' model with all the features of the Ultra model, without solar input and with a second battery charger.
