4.6. Electrical connections
WARNING: Check the polarity before connecting the battery and PV voltage.
WARNING: Follow the correct installation procedure described in this chapter.
IMPORTANT: Torque the battery and PV connections at 2.4Nm.
Connection order electrical connections:
1. Connect the battery: allow the solar charger to automatically recognise the system voltage (wait 10 seconds).
2. It is recommended to verify system voltage: use VictronConnect or an external control display.
3. Connect the PV.
4. Connect the applicable other connections: such as the remote on/off connector, the programmable relay connector, the
VE.Can port or the VE.Direct port.
The correct connection order is necessary to allow the automatic system voltage detection to setup properly. It is only allowed to
connect PV first when the system voltage is manually set before connecting the battery. Not following the correct procedures can
disable or damage the charger and/or the installation.
See the below figure on how the basic electrical connections are made:
