5. Opsætning og installation
Follow these steps for proper installation of your solar charge controller.
5.1 Montering af controlleren
- Vælg et tørt, godt ventileret sted, beskyttet mod direkte sollys, høje temperaturer og fugt.
- Ensure there is sufficient space around the controller for heat dissipation, especially around the cooling fins.
- Mount the controller vertically on a solid surface using the provided screws.
5.2 Ledningsforbindelser
Refer to the wiring diagrams below for correct connection sequence. Always connect in the following order:
- Tilslut batteriet: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage.
- Tilslut solpanelet: Connect the solar panel array to the controller's PV terminals. Ensure correct polarity.
- Tilslut DC-belastningen (valgfrit): Tilslut DC-belastningen til regulatorens belastningsterminaler. Sørg for korrekt polaritet.
To disconnect the system, follow the reverse order: disconnect load, then solar panel, then battery.
