System choice

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

system.

n

A battery voltage of 24 V is selected for this system to allow for smaller

cable sizes.

n

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.

n

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.

n

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.

Easily customizable favourite pages show all relevant system information at

Digital distribution

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.
