Observe the following instructions when connecting the MPP solar charger:
• Connect the house battery before connecting the solar panels.
• Do not use ferrules. Strip the cable ends as follows:
– Signal cable 9 mm (0.5 – 1.5 mm²)
– Charging cable 12 mm
• Connect several solar modules only in parallel and up to the rated power of the MPP solar char-
ger.
• In the case of two or more batteries, parallel connection is permissible if the batteries are of the
same type, capacity and age. Connect the batteries diagonally.
• For Dometic Büttner LiFePO4 batteries: To ensure measuring the internal temperature of the
battery use the temperature sensor connector to connect the probe of the temperature sensor
to the negative terminal of the house battery.
