LED error indication
The battery module shows an error indication through its status LEDs instead of the normal ready or working pattern.
Common causes
- Module-level fault reported by the BMS
- Communication loss between modules
- Temperature or voltage limit reached
- Firmware or address mismatch after module work
Safe checks
- 1Record the LED colour, blink count and which module shows it.
- 2Check whether the rest of the system still serves the property.
- 3Do not open battery modules or remove covers — they store energy after shutdown.
- 4Contact a certified installer with the LED pattern.
When to call a technician
Call a qualified technician if the device repeats the fault after a manufacturer-approved restart, shows a burning smell, has damaged or discoloured wiring, or if the symptom involves the battery, inverter power stage or any sealed high-voltage component.
