The Mass Combi Pro fits perfectly into a Mastervolt system.
All components are easily connected via MasterBus and installation
can be controlled and monitored intuitively, even with just one
EasyView touchscreen. This will provide and manage all information
about the Combi, the batteries and other sources such as the
generator, grid or solar panels. The system is also suitable for
Digital Switching, Mastervolt’s decentralised digital switching
A battery voltage of 24 V is selected for this system to allow for smaller
Batteries: 3 x MLI Ultra 24/5000
The total of AC and DC consumers requires around 4 kWh. The additional
alternator can charge 1 kWh in half an hour. After four days, the batteries
are discharged = 12 kWh (4x 4-1). Totally discharging the batteries is not
advisable so opt for a maximum of 80 % discharge = 15 kWh. Taking into
account the various appliances and required peak loads we suggest a 24 V
system. The required battery capacity is 15 kWh.
Charger/inverter: Mass Combi Pro 24/3500-100
432 Ah (3x 80 % x 180 Ah) needs at least 25 % of the battery capacity for
charging power, so in this case we chose for a 100 A charging power via
the Mass Combi Pro. The Mass Combi Pro has a battery charger that allows
you to safely, quickly and completely charge two battery banks; starter and
service batteries can be separately charged. Additionally the Mass Combi
Pro can be used to convert the power for your AC applications, so using
everything simultaneously is also possible.
Monitoring: EasyView 5
Waterproof system monitor with intuitive touchscreen. Thanks to the colour
touchscreen and multi-language menu, the display is a pleasure to operate.

The products in this system communicate with each other via MasterBus.
This brilliantly simple platform for communication and connections ensures
that all components ‘speak’ the same language. The result is a single
communication protocol with high-speed CANbus technology.
2 x DC Distribution 500
This distribution model connects up to four DC devices to the DC groups,
such as a battery charger, inverter, alternators and solar panels.
