Flashing white indicator
A white flashing indicator usually indicates an idle or sleep state rather than a fault.
Common causes
- Unit idle with no active charge or discharge request
- Unit entering sleep to conserve energy
- Commissioning or wake-up sequence in progress
Safe checks
- 1Check the unit status in the owner app.
- 2Confirm the system is still serving the property.
- 3Wait for the next scheduled activity before investigating further.
- 4Only escalate if the app also reports a fault.

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.
