5. Instalación y configuración
5.1 Precauciones de seguridad
- Ensure all wiring is done by qualified personnel.
- No retire la cubierta; No hay partes reparables por el usuario adentro.
- This equipment is designed for DC voltage to DC equipment.
- Always disconnect power sources before making or breaking connections.
5.2 Montaje
- Mount the controller vertically on a wall or other suitable surface.
- Ensure adequate air circulation around the controller for proper heat dissipation. Avoid mounting in enclosed spaces without ventilation.
- Keep the controller away from flammable materials, corrosive gases, and direct sunlight.
5.3 Secuencia de cableado
Follow this sequence carefully to avoid damage to the controller or other components:
- Conecte la batería: Connect the battery to the controller's battery terminals (BATT). Ensure correct polarity (positive to positive, negative to negative). The controller will detect the system voltage (12V o 24V) automáticamente.
- Conecte el panel solar (PV): Connect the solar panel array to the controller's PV terminals. Ensure correct polarity. The controller will begin charging the battery.
- Conecte la carga de CC (opcional): Conecte la carga de CC a los terminales de carga del controlador. Asegúrese de que la polaridad sea correcta.
- Conectar el cable de comunicación (opcional): If using the Modbus communication feature, connect the RS485 (RJ45) cable to the COM port.
WARNING: Never connect the solar panel array to the controller without a battery connected first. This can cause damage to the controller.
6. Instrucciones de funcionamiento

- Sin energía/pantalla:
- Check battery connections and ensure they are secure and have correct polarity.
- Verifique el volumen de la bateríatage is within the acceptable range (8-32V).
- Sin carga desde PV:
- Ensure solar panel connections are secure and have correct polarity.
- Compruebe el voltaje del circuito abierto fotovoltaicotage and ensure it is within the controller's limits (Max. 150V).
- Verify there is sufficient sunlight reaching the solar panels.
- La carga no funciona:
- Verifique las conexiones de carga y la polaridad.
- Ensure the battery has sufficient charge. The controller will disconnect the load if battery voltage es demasiado bajo.
- Verify the selected load work mode is appropriate (e.g., not in "off" mode).
- Check for overcurrent protection; if the load draws too much current, the controller may shut off the output.
- Comportamiento inusual:
- Asegúrese de que el tipo de batería correcto esté seleccionado en la configuración del controlador.
- Check for any error codes or indicators on the controller's display.
