5. Operating Instructions

The controller features an LCD display and buttons for easy operation and monitoring. It also supports Bluetooth connectivity for app-based control.

5.1 LCD Display and Buttons

The LCD displays various parameters such as PV voltage, battery voltage, charging current, and load status. Use the buttons to navigate through the display pages and adjust settings.

• Short Press: Cycles through different display pages (e.g., operating status, fault information, battery type, voltage data).
• Long Press: Enters or exits the setting mode for adjustable parameters.
• Up/Down Buttons: Used to adjust values when in setting mode.

5.2 Battery Type Selection

The controller automatically identifies 12V/24V battery types. However, you can manually select the battery type if needed, especially for lithium batteries to ensure proper charging parameters.

• Long press the 'SET' button to enter parameter setting mode.
• Use the 'UP' or 'DOWN' buttons to navigate to the battery type setting.
• Use the 'SET' button to select the desired battery type (GEL, SLA, FLD, LFP, etc.).
• Long press 'SET' again to save and exit.

5.3 Bluetooth APP Monitoring

Download the dedicated mobile application to monitor your system remotely and adjust parameters. The app provides real-time data and historical trends.

• Ensure Bluetooth is enabled on your mobile device.
• Open the ECO-WORTHY app and search for your controller.
• Connect to the controller to view real-time data and access settings.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar charge controller.

• Periodically inspect all wiring connections for tightness and corrosion.
• Clean the controller's exterior with a dry cloth to remove dust and debris.
• Ensure the ventilation areas are clear and unobstructed.
• Check the battery terminals for any signs of corrosion and clean if necessary.

7. Troubleshooting

If you encounter issues with your controller, refer to the following common problems and solutions:

• Controller Not Powering On: Check battery connections and ensure correct polarity. Verify battery voltage is within the operating range.
• No Charging Current: Check solar panel connections and ensure they are receiving sufficient sunlight. Verify solar panel voltage is within the controller's input range.
• Load Not Working: Check load connections and ensure correct polarity. Verify load output is enabled in the controller settings. Check for any short circuits in the load wiring.
