Product Specifications

Powerful, complete and versatile
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 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.
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.
Energy saving
The integrated solar charge regulator is preferred over the AC-in, so that the batteries will initially only be
charged by green solar energy. A CO2 and cost-effective solution to keep your batteries in perfect condition.
Quiet operation
The Mass 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.
Parallel and 3-phase operation
The Mass Combi Ultra functionality goes beyond stand-alone operation, the design also allows parallel and
3-phase configurations for larger applications up to 35 kW. For larger systems, an external transfer system is
required.
Dual AC inputs and outputs
The Mass Combi Ultra has inputs for generator or mains supply, each optimized for the power source. A
robust intelligent transfer system switches seamlessly between AC power, generator and inverter, and
ensures a constant power supply. Flickering lights or failure of electronic equipment belong to the past.
Separate AC outputs provide the ability to power heavy users via mains and/or generator.
