| Alarm light illuminated | Over-voltage, under-voltage, over-current, high/low temperature, short circuit. | Check the HumsiENK app for specific alarm details. Address the underlying cause (e.g., reduce load, check charging source, allow battery to cool/warm). The BMS will protect the battery by shutting it down if necessary. |
| Bluetooth connection issues | Out of range, Bluetooth disabled on device, app issues. | Ensure you are within Bluetooth range. Verify Bluetooth is enabled on your mobile device. Restart the app or your device. |
| Reduced capacity or runtime | Aging battery, extreme operating conditions, incorrect charging parameters. | While LiFePO4 batteries have a long life, capacity can degrade over many years. Ensure operating temperatures are within range. Verify charging parameters are set correctly by your inverter/charge controller. |
