Red LED indicator flashing. Fault condition 1 of 5: Battery voltage is too low.
CauseBattery voltage is too low.
Recommended fixStop discharging and recharge the battery from mains or PV as soon as possible. The flashing clears once pack voltage recovers into the normal range; if it continues after a full recharge, restart the unit and contact your installer.

Red LED indicator flashing. Fault condition 2 of 5: Cell voltage is too low.
CauseCell voltage is too low.
Recommended fixRecharge the battery promptly — a cell below its low-voltage limit normally recovers once charging brings it back into range. If the flashing returns after a full charge, the pack may have a weak cell; restart the unit and contact your installer.

Red LED indicator flashing. Fault condition 3 of 5: Cell temperature is too high.
CauseCell temperature is too high.
Recommended fixStop charging and discharging and let the battery cool. Check ambient temperature and ventilation around the unit; the protection recovers automatically once cell temperature is back in range. Restart the unit if the flashing persists after cooling.
