5.2 Wiring Connections

Important: Always connect the battery first, then the solar panels. Disconnect in reverse order (solar panels first, then battery).

1. Battery Connection: Connect the positive and negative battery cables to the corresponding terminals on the controller. Ensure correct polarity. Install a DC circuit breaker between the battery and the controller.
2. Solar Panel Connection: Connect the positive and negative solar panel cables to the corresponding PV input terminals on the controller. Ensure correct polarity. Install a DC circuit breaker between the solar panels and the controller.
3. Load Connection (Optional): If using the load terminals, connect your DC loads to the designated terminals.
