3.3. System examples
Below you will find a selection of system examples. Note that there are many other possibilities. It is mandatory to study
as there can be different types of cable interfaces within a product group to control chargers, inverters and
inverter/chargers from the Load and Charge disconnect outputs of the BMS.

Application example with MultiPlus Compact and MPPT
This is a typical system example for smaller RVs and Boats, which has a MultiPlus Compact 12/2000 connected to the
port. In case of low cell voltage the port disconnects the MultiPlus and prevents the Multi from further discharging the
battery. A SmartSolar MPPT 75/15 connected directly to the lithium battery is controlled by the BMS via a VE.Direct non-inverting
remote on/off cable. In the event of high cell voltage or high temperature, the Charge disconnect output will stop the MPPT from
charging. In addition, the system includes a SmartShunt to monitor the lithium battery.

Application example with MultiPlus and Smart BatteryProtect
Another example where a Multi is connected directly to the port, eliminating the need to control it via the Charge and
Load disconnect output, saving additional wiring. A Smart BatteryProtect controls DC loads. The Load disconnect port of the BMS
switches off the OUT port of the BatteryProtect in the event of a low cell voltage, thus preventing the lithium battery from further
discharging. In addition, the system includes a SmartShunt to monitor the lithium battery.
