| Code | What it means | What to do | Service | Manual |
|---|---|---|---|---|
| 1 Battery Pack Low Temperature | Battery temperature is too low. | Wait until the temperature rises above 0°C. It recovers automatically when the temperature increases. | owner | p. 25 |
| 10 Charging Board Output Overcurrent | DC output current is too high. | Stop DC output. Check the specifications and ratings of the connected equipment. | owner | p. 25 |
| 11 Charging Board Output Short Circuit | A short circuit is detected on the DC output. | Stop DC output. Check the specifications and ratings of the connected equipment. | owner | p. 25 |
| 12 Charging Board Input Undervoltage | DC input voltage is too low for charging. | Increase the input voltage to the specified range and retry. | owner | p. 25 |
| 13 Charging Board Overtemperature | The charging board is overheating during DC charging. | Temporarily suspend DC charging. Check whether the charging equipment or cables are abnormal. | owner | p. 25 |
| 2 Battery Pack High Temperature | Battery temperature is too high. | Wait until the temperature drops below 50°C. It recovers automatically when the temperature decreases. | owner | p. 25 |
| 3 Battery Pack Overvoltage | Battery pack voltage is above its normal range. | Temporarily suspend charging or discharging. Check the load or charging equipment, and retry if no abnormalities are found. | owner | p. 25 |
| 4 Battery Pack Undervoltage | Battery pack voltage is below its normal range. | Temporarily suspend charging or discharging. Check the load or charging equipment, and retry if no abnormalities are found. | owner | p. 25 |
| 5 Battery Pack Short Circuit | A short circuit is detected at the battery pack's cascade or equipment connection port. | Check whether the cascade connection port (equipment connection port) is short-circuited. | owner | p. 25 |
| 6 Battery Pack Charging Overcurrent | Charging current into the battery pack is too high. | Suspend charging. If caused by overload or temperature rise, reduce the load and retry. | owner | p. 25 |
| 7 Battery Pack Discharging Overcurrent | Discharge current from the battery pack is too high. | Suspend discharging. If caused by overload or temperature rise, reduce the load and retry. | owner | p. 25 |
| 8 Charging Board Input Overcurrent | DC charging input current is too high. | Stop DC charging. Check the specifications and ratings of the connected equipment. | owner | p. 25 |
| 9 Charging Board Input Overvoltage | DC charging input voltage is too high. | Stop DC charging. Check the specifications and ratings of the connected equipment. | owner | p. 25 |
| 14 DC Output Overvoltage | DC output voltage is too high. | Stop output. Confirm the connected load is appropriate. If the shutdown persists, contact PECRON. | dealer | p. 26 |
| 15 DC Output Overcurrent | DC output current is too high. | Stop output. Confirm the connected load is appropriate. If the shutdown persists, contact PECRON. | dealer | p. 26 |
| 16 DC Output Overtemperature | The DC output is overheating. | Stop output. Confirm the connected load is appropriate. If the shutdown persists, contact PECRON. | dealer | p. 26 |
| 17 Mains Voltage Abnormality | Possibly an inverter failure or abnormal AC charging voltage. | Stop using the unit and contact PECRON. | dealer | p. 26 |
| 18 Mains Frequency Abnormality | Output frequency is abnormal, possibly due to an inverter failure. | Stop using the unit and contact PECRON. | dealer | p. 26 |
| 19 Mains Input Overload | AC input load is too high during charging. | Stop charging. Retry charging after the abnormality is resolved. | owner | p. 26 |
| 20 Inverter Output Overload | The connected AC load exceeds the inverter's rating, and output has stopped. | Output has stopped. This load cannot be used. Confirm the load rating. | owner | p. 26 |
| 21 Inverter Output Short Circuit | A short circuit is detected at the AC output socket. | Check whether the output socket is short-circuited. If abnormalities are found, stop using the unit. | owner | p. 26 |
| 22 Inverter Overtemperature | The inverter is overheating and output has stopped. | Output has stopped. Place the device in a cool, dry location and allow sufficient heat dissipation. | owner | p. 26 |
| 23 Fan Failure | An abnormality is detected in the cooling fan. | Stop using the unit, then replace the fan or contact PECRON. | dealer | p. 26 |
| 24 DC Output Short Circuit | A short circuit is detected on the DC output side. | Check whether the external DC output wiring is short-circuited. If the error reappears immediately after turning the output on, there may be an internal fault; contact PECRON. | dealer | p. 26 |
