4. Configuració i instal·lació
Follow these steps carefully to install your solar charge controller:
- Preparació del cablejat: Ensure all wires are properly sized for your system's current and voltage. Strip wire ends approximately 8-10mm.
- Connecta la bateria: Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The LCD will light up.
- Connecteu el panell solar: Connect the solar panel to the controller's solar panel terminals (marked with a solar panel symbol). Ensure correct polarity.
- Connectar càrrega: Connect the DC load to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
