4. Installatie en installatie

Proper installation is crucial for the safe and efficient operation of your solar charge controller.

4.1. De controller monteren

Mount the controller vertically on a flat, non-flammable surface in a well-ventilated area. Ensure there is sufficient space around the controller for heat dissipation. The design allows for hidden wiring installation:

• Pull down the bottom cover box.
• Sluit de bedrading aan zoals hieronder beschreven.
• Cover the bottom cover after installation to conceal wiring.

4.2. Bedradingsvolgorde

Follow this wiring sequence strictly to avoid damage to the controller or other components:

1. Sluit de batterij aan: Connect the battery to the controller's battery terminals (positive to positive, negative to negative). The controller will automatically detect the system voltage (12V of 24V).
2. Sluit het zonnepaneel aan: Connect the solar panel to the controller's PV terminals (positive to positive, negative to negative).
3. De belasting aansluiten: Connect the DC load to the controller's load terminals (positive to positive, negative to negative).

Important Note: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
