This diagram illustrates the correct connection order for the battery, solar panels, DC load, and optional inverter. A temperature sensor is also shown.

4.2 Passos de connexió

1. Connecteu primer la bateria: Connect the battery to the charge controller's battery terminals. Ensure correct polarity. The controller will auto-detect 12V or 24V system voltage.
2. Connecteu els panells solars: Connect the solar panels to the PV input terminals. Ensure correct polarity. The controller will begin charging if sufficient sunlight is available.
3. Connect DC Load (Optional): If using a DC load directly from the controller, connect it to the load terminals.
4. Connect Inverter (Optional): If using an inverter, connect it to the battery terminals (not directly to the load terminals of the controller).
5. Connect Temperature Sensor: For accurate temperature compensation, connect the provided temperature sensor to the designated port on the controller and place the sensor near the battery.

Ordre de desconnexió: To disconnect the system, always follow the reverse order: Disconnect load, then solar panels, then battery.

5. Instruccions de funcionament

This section details how to monitor and configure your charge controller using its integrated LCD display and the optional Bluetooth mobile application.
