The LCD display provides real-time information on battery voltage, charging current, discharge current, and system status. The buttons allow you to navigate through display modes and adjust certain charging and discharging parameters.

3.2 Paràmetres ajustables

The controller allows for adjustment of floating charge voltage, tall de descàrrega voltage, and discharge recovery voltage. Refer to the on-screen menu for specific adjustment procedures. These parameters are factory-set to default values suitable for most lead-acid batteries but can be customized if needed.

3.3 Sortida USB

The controller includes a 5V/2A USB output for charging small electronic devices. This output is active when the battery has sufficient charge.

4. Manteniment

To ensure the longevity and optimal performance of your VGEBY YCX-003 MPPT Solar Charge Controller, periodic maintenance is recommended.

• Neteja: Mantingueu el controlador net i lliure de pols i brutícia. Feu servir un drap sec per netejar-lo.
• Connexions: Reviseu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i sense corrosió. Les connexions soltes poden provocar pèrdues de corrent o sobreescalfament.
• Ventilació: Assegureu-vos que el controlador estigui instal·lat en una zona ben ventilada per evitar el sobreescalfament.

5. Solució De Problemes

The VGEBY YCX-003 controller is designed with several built-in protection features. If the system is not operating as expected, check the following:

• Sense pantalla/alimentació: Check battery connections and ensure the battery has sufficient voltage.
• Sense càrrega: Verify solar panel connections and ensure adequate sunlight. Check for reverse polarity on solar panel connections.
• La càrrega no funciona: Check load connections and ensure the battery voltage is above the discharge recovery voltage. The controller automatically cuts off the load if battery voltage és massa baixa.
• Error Codes/Warnings: The controller has built-in protections for overheating, overcurrent, short circuit, open circuit, and reverse connection. If a fault occurs, the controller will automatically recover once the issue is resolved. Consult the display for any specific indicators.
• Polaritat inversa: The controller has reverse polarity protection for both the battery and solar panels. If connected incorrectly, the controller will not operate until the polarity is corrected.
