Instrucións de configuración
Follow these steps to correctly connect your solar controller to the solar panel, battery, and load. Ensure all power sources are disconnected before making any connections.
- Conecte a batería: Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V ou 24V).
- Conecta o panel solar: Connect the solar panel to the controller's solar panel terminals (marked with a solar panel symbol). Ensure correct polarity.
- Conectar a carga: Connect the DC load to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.
Importante: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load first, then solar panel, then battery.

Mantemento
To ensure optimal performance and longevity of your solar controller, perform the following maintenance checks periodically:
- Limpeza: Manteña o controlador limpo e libre de po e residuos. Use un pano seco para limpar.
- Conexións: Periodically check all wiring connections for tightness and corrosion. Loose connections can cause voltagcaídas de e e sobrequecemento.
- Ventilación: Asegúrese de que a zona de instalación permaneza ben ventilada para evitar o sobrequecemento do controlador.
- Saúde da batería: Monitor your battery's health and ensure it is properly maintained according to the battery manufacturer's guidelines.
Resolución de problemas
If you encounter issues with your solar controller, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen visualización na pantalla LCD | Batería non conectada ou de baixo volumetage; reversed polarity. | Comprobe as conexións da batería e o voltage. Asegúrese de que a polaridade sexa correcta. |
| A batería non se está cargando | Solar panel not connected or insufficient sunlight; reversed polarity; faulty solar panel. | Check solar panel connections and ensure adequate sunlight. Verify polarity. Test solar panel output. |
| A carga non funciona | Load not connected or reversed polarity; battery low; load overcurrent protection activated. | Check load connections and polarity. Ensure battery is sufficiently charged. Reduce load or check for short circuits. |
| Sobrequecemento do controlador | Mala ventilación; carga excesiva. | Ensure adequate airflow around the controller. Reduce connected load if possible. |
