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 Pasos de conexión

1. Conecta primeiro a batería: Connect the battery to the charge controller's battery terminals. Ensure correct polarity. The controller will auto-detect 12V or 24V system voltage.
2. Conectar paneis solares: Connect the solar panels to the PV input terminals. Ensure correct polarity. The controller will begin charging if sufficient sunlight is available.
3. Conectar a carga de CC (opcional): If using a DC load directly from the controller, connect it to the load terminals.
4. Conectar o inversor (opcional): If using an inverter, connect it to the battery terminals (not directly to the load terminals of the controller).
5. Conectar o sensor de temperatura: For accurate temperature compensation, connect the provided temperature sensor to the designated port on the controller and place the sensor near the battery.

Disconnection Order: To disconnect the system, always follow the reverse order: Disconnect load, then solar panels, then battery.

5. Instrucións de funcionamento

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