3. Configuración e instalación
Una instalación correcta es crucial para el funcionamiento seguro y eficiente de su controlador de carga solar. Siga estos pasos cuidadosamente:
- Preparar el cableado: Ensure all wires are of appropriate gauge for the current and length, and that all connections are clean and secure.
- Conecte la batería: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12 V o 24 V).
- Conectar el panel solar: Connect the solar panel array to the charge controller. Again, observe correct polarity. The controller will begin charging the battery.
- Conectar carga: Finally, connect the DC load to the charge controller's load terminals. Do not exceed the maximum rated load current.
Importante: Siempre conecte la batería primero y desconéctela por último para evitar dañar el controlador.

4. Instrucciones de funcionamiento
4.1. Pantalla LCD
The LCD display provides real-time information about the system's status. It shows battery voltage, charging current, discharging current, battery state of charge, and various error indicators.
Figure 3: Close-up of the LCD display and control buttons for navigation and settings.
4.2. Funciones de los botones
The controller features two buttons for navigation and setting adjustments:
- Left Button (Menu/Select): Used to cycle through display screens and enter/confirm settings.
- Right Button (Up/Adjust): Used to increase values or navigate options within settings.
4.3. Modos de control de carga
The controller supports multiple load control modes to suit different application needs:
- Modo normal: Load is continuously ON or OFF based on manual setting.
- Modo sensor: Load turns ON automatically when it gets dark and OFF when it gets light (e.g., for street lights).
- Modo temporizador: Load turns ON when it gets dark and stays ON for a set number of hours.
4.4. Selección del tipo de batería
To ensure optimal charging, select the correct battery type in the controller settings:
- Sellado: For sealed lead-acid batteries.
- Gel: For gel batteries.
- Inundado: For flooded (wet cell) lead-acid batteries.
Refer to the detailed instructions in the full manual for specific steps on navigating menus and adjusting settings.
5. Mantenimiento
El mantenimiento regular garantiza la longevidad y el rendimiento óptimo de su controlador de carga solar:
- Limpieza: Mantenga el controlador limpio y libre de polvo y residuos. Utilice un paño seco para limpiarlo.
- Comprobaciones de conexión: Inspeccione periódicamente todas las conexiones del cableado para asegurarse de que estén bien apretadas y libres de corrosión. Las conexiones sueltas pueden causar sobrecalentamiento y un rendimiento deficiente.
- Ventilación: Asegúrese de que el controlador tenga ventilación adecuada para evitar el sobrecalentamiento. No obstruya los orificios de ventilación.
- Condiciones ambientales: Operate the controller within its specified temperature range (-20℃ to +55℃) and avoid exposure to direct sunlight or excessive moisture. The waterproof grade is IP32.
