2. Información de seguridad
Please read and understand all safety instructions before installation and operation to prevent injury or damage to the controller and connected equipment.
- Conexión de la batería primero: Always connect the battery to the controller first. Ensure the battery voltage is sufficient for the controller to recognize the correct system voltage.
- NEVER Connect Solar Panel Array Without Battery: Do not connect the solar panel array to the controller before connecting the battery.
- Secuencia de desmontaje: The disassembly sequence is contrary to the wiring order (disconnect solar panels first, then battery).
- Conexión del inversor/cargador: DO NOT connect any Inverter, wind turbine, alternator, or external charger directly into the charge controller. Connect the Inverter directly to the battery.
- Vol de entrada solartage: Asegúrese de que el volumen de entrada solartage is at least 3V higher than the battery's voltage and that the total input power is within the specified range.
- Ubicación de la instalación: DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating.
- Ventilación: Remove all clutter around the controller to reduce interference and ensure enough space for heat dissipation (approximately 20cm clearance).
- Conexiones estrechas: Ensure all connections going into and from the controller are tight.
- Polaridad: DO NOT let the positive (+) and negative (-) terminals of the battery touch each other.

4. Configuración e instalación
Proper installation is crucial for the performance and longevity of your solar charge controller. Follow these steps carefully:
- Montaje: Install the controller in a well-ventilated area, away from direct sunlight and heat sources. Ensure at least 20cm of clear space around the unit for proper airflow.
- Conexión de la batería: Connect the battery to the controller first. Ensure the battery voltage is sufficient for the controller to auto-detect the system voltagy (12V/24V/36V/48V).
- Conexión del panel solar: After the battery is connected, connect the solar panel array to the controller. Ensure the maximum input voltage (150V PV) and power (1140W for 12V, 2260W for 24V, 3420W for 36V, 4540W for 48V) are not exceeded. The MPPT best working voltage range is DC18V-DC80V (12V), DC30V-DC100V (24V), DC65V-DC150V (48V).
- Conexión de carga de CC: Connect your DC loads to the designated terminals.
- Apretar las conexiones: Double-check all wiring connections to ensure they are secure and tight to prevent loose connections and potential hazards.

6. Mantenimiento
Regular maintenance ensures the optimal performance and lifespan of your solar charge controller.
- Comprobaciones de conexión: Inspeccione periódicamente todas las conexiones del cableado para asegurarse de que permanezcan firmes y libres de corrosión.
- Limpieza: Mantenga el controlador limpio y libre de polvo y residuos. Utilice un paño seco para limpiarlo.

7. Solución de problemas
Esta sección aborda problemas comunes que puede encontrar con su controlador de carga solar.
- Charging Indicator On/Off: If the charging indicator is intermittently on and off, and the charging current fluctuates, this is generally normal. It often occurs on cloudy days or in the evening when light is insufficient, indicating the controller is adjusting to available solar input.
- Controller Buzzing: If the controller produces a buzzing sound, it is typically due to the internal fan operating to dissipate heat. This is a normal function, especially under heavy load or high ambient temperatures. Allow the fan to operate as needed.
- Corriente de carga baja: If the charging current is almost zero when the controller is in floating charge mode, it may indicate that the solar input power is too low for the maximum input power capacity, or the battery is already fully charged.
