Troubleshooting

This section provides solutions to common issues you might encounter. For complex problems, contact technical support.

No Power Output

• Check Connections: Ensure all cables between the battery, inverter, and load are securely connected.
• Battery State of Charge: Verify the battery has sufficient charge. If low, check solar panel input or grid connection for charging.
• Inverter Status: Check the inverter's display for error codes or status indicators. Refer to the inverter manual.

BMS Error Indication

• Overcharge/Over-discharge: The BMS may trigger protection if the battery is overcharged or over-discharged. The system should automatically recover once conditions normalize.
• Temperature Protection: If the battery temperature is too high or too low, the BMS will activate protection. Move the system to a suitable environment.
• Short Circuit: A short circuit will cause the BMS to cut off power. Identify and resolve the short circuit before restarting.

Inconsistent Performance

• Communication Issue: Ensure the communication cable between the battery and inverter is properly connected and configured.
• Load Management: Verify that the connected load does not exceed the system's capacity.
