C06Fault

Felicity battery error C06

Discharge overcurrent

Faultthe battery enters fault protection and stops normal operation until the fault is cleared — how it is shown (LED pattern or display code) depends on the model.

The exact meaning depends on your model:

FLA12100

BatteryFault

Also applies to:FLA48200

What it means

Discharge overcurrent

Cause: The discharging current reached the BMS trigger value and stayed there for 15 seconds, activating discharge overcurrent protection: the load or inverter is drawing more current than the pack's discharge limit. The battery disables both charging input and discharging output while in fault mode.

How to fix it

  1. Restart the unit.
  2. If the error persists, contact the repair center.

FLA48250

BatteryCritical

What it means

Discharge overcurrentDischarge current exceeds the BMS protection limit.

Cause: The discharging current reached the BMS trigger value and stayed there for 15 seconds, activating discharge overcurrent protection: the load or inverter is drawing more current than the pack's discharge limit. The battery disables both charging input and discharging output while in fault mode.

How to fix it

  1. Restart the unit.
  2. If the error persists, contact the repair center.

FLA48250-EU

BatteryFault

What it means

C06Discharge overcurrent.

Cause: The discharging current reached the BMS trigger value and stayed there for 15 seconds, activating discharge overcurrent protection: the load or inverter is drawing more current than the pack's discharge limit. The battery disables both charging input and discharging output while in fault mode.

How to fix it

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

FLA48500

BatteryFault

Also applies to:HE-GF-FLA-48500

What it means

Discharge overcurrentDischarging current exceeded the allowable limit.

Cause: Discharge current above recommended (≤200A continuous, 300A 15s peak).

How to fix it

  1. Restart the unit.
  2. If the error persists, contact the repair center.

FLB48314TG1

BatteryFault

What it means

Discharging Overcurrent ProtectionDischarging current reached the trigger value and lasted for 15 seconds. Battery enters fault mode, disabling both charging input and discharging output.

Cause: Discharging current stayed above the BMS trigger value for 15 seconds — the connected load or the inverter's discharge-current setting exceeds what the pack is rated to deliver.

How to fix it

  1. Power down the inverter, wait 5 minutes for capacitors to discharge, then restart.
  2. If the fault recurs immediately or repeatedly, record the exact code and contact your installer or the manufacturer's service line.

FLS48100SG2

BatteryFault

What it means

Discharge overcurrentDischarge overcurrent. Discharging current reached the trigger value for 15 seconds; discharging overcurrent protection activated and the battery entered fault mode disabling both charge input and discharge output.

Cause: Discharging current exceeded trigger value for 15 s. Load or inverter discharge current may be too high.

How to fix it

  1. Fault auto-clears after 1 minute.
  2. After 10 occurrences, manual restart is required.
  3. Restart the unit; if the error persists, return to repair centre.
  4. Reduce inverter discharge current to recommended value.

LPBF48100-M

BatteryFault

What it means

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

Cause: Load drew more current than the recommended discharge limit (recommended <=50 A, Max 100 A for 15 s per section 2.3) or a short circuit on the DC output. Section 1.3 item 10 warns NEVER to cause AC output / DC input short circuits.

How to fix it

  1. Restart the unit, if the error persists, contact the repair center.
  2. Remove or reduce the load and check DC wiring for short circuits.

BatteryFault

Also applies to:LPBF48100-H

What it means

Battery discharge overcurrentDischarge current has exceeded the BMS protection limit.

Cause: Discharge current above the maximum discharge rating (>120A on LPBF48200-H).

How to fix it

Restart the unit; if the error persists, contact the repair center.
