Use the Bluetooth App for real-time monitoring of battery status, charge/discharge rates, and system performance. The app also allows for system configuration and firmware updates.

4.3 Firmware Updates

The system supports firmware updates via USB, Wi-Fi (optional), or remote upgrade (compatible with Deye inverters). Refer to the specific Deye inverter manual for remote upgrade procedures.

5. Maintenance

The Deye BOS-B Pro-A3 battery system is designed for minimal maintenance due to its robust LiFePO4 chemistry and smart thermal management.

  • Regular Inspection: Periodically check all cable connections for tightness and signs of wear or corrosion.
  • Ventilation: Ensure the smart fan cooling system is unobstructed and operating correctly. Keep the area around the battery modules clear to allow for proper airflow.
  • Cleaning: Keep the exterior of the battery modules clean and free of dust. Use a dry, soft cloth for cleaning.
  • Storage: If the system is to be stored for an extended period, ensure it is charged to an appropriate level (e.g., 50% State of Charge) and stored within the recommended temperature range (0 ~ 35 °C). The low self-discharge rate allows for storage up to 6 months without charging.

6. Troubleshooting

This section provides general guidance for common issues. For detailed troubleshooting or issues not covered here, please contact technical support.

  • System Not Powering On:
    • Check all circuit breakers (DC and AC) to ensure they are in the ON position.
    • Verify all power cables are securely connected.
    • Check the system's display or app for error codes.
  • Reduced Performance:
    • Ensure proper ventilation for the smart fan cooling system. Overheating can reduce performance.
    • Check the battery's State of Charge (SOC) via the app.
    • Verify that the inverter is operating correctly and communicating with the battery system.
  • Communication Issues:
    • Check the physical connections for TCP, RS485, or CAN ports.
    • Ensure the Bluetooth on your device is enabled and correctly paired with the battery system.
    • Restart the communication module if possible.
