Figura 4: System connection diagram showing the solar panels, battery (12Vdc or 24Vdc), DC loads (Max 120W), and an optional inverter for AC loads (110Vac or 220Vac).

5.2 Pasos de conexión

  1. Conecte a batería: Connect the battery to the charge controller's positive and negative terminals. The controller will automatically detect 12V or 24V battery voltage. Ensure the battery is charged enough for the controller to recognize it.
  2. Conecta o panel solar: Connect the photovoltaic module (solar panel) to the charge controller's positive and negative terminals.
  3. Conectar a carga: Connect the load (e.g., DC lights, fans) to the charge controller's positive and negative terminals.

Importante: When disconnecting the system, follow the reverse order: first disconnect the load, then the solar panel, and finally the battery. Incorrect disconnection sequence can damage the controller.

Recommended wire gauge for RBL-30A-DE is 12 AWG.

6. Instrucións de funcionamento

The controller features an LCD display and three buttons for navigation and parameter settings.

  • Botón MENÚ: Short press to switch between different display interfaces. Long press to enter or exit parameter setting mode.
  • UP Button (▲): Press to increase a value or browse upwards in menus.
  • DOWN Button (▼): Press to decrease a value or browse downwards in menus.

6.1 Display Interfaces and Parameter Settings
