5. Configuración e cableado
Follow these steps carefully to connect your solar charge controller to the battery, solar panel, and load. Incorrect wiring sequence can damage the controller.
5.1 Diagrama de cableado
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
- 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.
- Conecta o panel solar: Connect the photovoltaic module (solar panel) to the charge controller's positive and negative terminals.
- 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
Figura 5: This diagram illustrates the navigation through the controller's LCD interfaces. From the main display, you can browse different interfaces by pressing the MENU button. To set parameters (interfaces 2-5), long press MENU to enter setting mode, use UP/DOWN to adjust values, and long press MENU again to save and exit. Long pressing MENU without changing values will restore default parameters.
The LCD will cycle through various displays including main display (battery voltage), float voltage, discharge reconnect voltage, discharge stop voltage, battery type, and work mode.
6.2 Parámetros axustables
In setting mode (long press MENU), you can adjust the following parameters:
- Float Charge Voltage (HVD): Default 13.7V (adjustable). This is the voltage at which the battery is maintained after being fully charged.
- Vol. de reconexión de descargatage (LVD): Default 12.6V (adjustable). The voltage at which the load will be reconnected after being disconnected due to low battery.
- Vol. de parada de descargatage (RVD): Default 10.7V (adjustable). The voltage at which the load will be disconnected to protect the battery from over-discharge.
- Tipo de batería: Select from B01 (Sealed), B02 (Gel), B03 (Flooded).
- B01 Sealed: Equalization 14.4V
- B02 Gel: Equalization 14.2V
- B03 Flooded: Equalization 14.6V
- Load Work Mode: Set the load output timer (e.g., 24 hours, 1-23 hours, 0 hours for manual control).
Atención: Adjusting parameters incorrectly can affect battery performance and lifespan. Refer to your battery manufacturer's specifications for optimal settings.
