Mass Combi Ultra 24V/3500W - 100A - 230V
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.
‘Pro’ Models
For professional applications. Mastervolt offers a ‘Pro’ model, featuring all
Ultra functions, but without the solar input and secondary battery charger.
Quiet operation
The Mass Combi Ultra and Mass Combi Pro 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 and Mass Combi Pro have 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.
