C05C05Fault
Description

Charge overcurrent.

Recommended fix

Restart the unit. if the error persists, contact the repair center. When the charging current reaches the trigger value and lasts for 15 seconds, charging overcurrent protection is activated, entering fault mode. The battery disables both charging input and discharging output. The fault is automatically cleared after 1 minute. After 10 occurrences, the fault can no longer clear automatically, requiring a manual battery restart.

C05Lade-Überstrom.Fault
Description

Charge overcurrent. Charging current reached the trigger value for 15 seconds; charging overcurrent protection activated and the battery entered fault mode disabling both charge input and discharge output.

Cause

Charging current exceeded trigger value for 15 s (Ladestrom überschritt den Auslösewert für 15 Sekunden). Inverter charge current setting may be too high.

Recommended fix

Fault auto-clears after 1 minute. After 10 occurrences, manual restart is required. Restart the unit; if the error persists, return to repair centre. Set inverter charge current to recommended value (60A x N, max 400A).

C05Battery charge overcurrent.Fault
Description

Charge over-current fault displayed on the LCD BMS fault code / flag screen (section 4.4).

Cause

Charge current exceeded the recommended limit. Per section 2.3 the recommended charge / discharge current is <=50 A and the Max Charge/Discharge Current (15 s) is 100 A; per section 2.4 Max. Charging Current is 50 A * N (N = number of packs in parallel).

Recommended fix

Restart the unit, if the error persists, contact the repair center. Reduce charge current at the charger / inverter to within 50 A per pack (section 2.4).
