### Error Codes
If the ERROR LED lights up, displaying an error code due to a failed grid or your PV generation system, contact your dealer for repair. This subsection describes the typical error codes.
**General Error Codes:**
- **E-00**: Internal switch operates abnormally.
- **E-05**: Configuration information, including settings, has been retrieved inappropriately at startup.
- **E-07**: Internal temperature information cannot be detected.
- **E-08**: Control circuit is functioning improperly.
- **E-09**: An extremely high internal temperature is detected.
- **E-20**: Input voltage has exceeded the maximum limit.
- **E-24**: Overcurrent occurred in the output.
- **E-25**: Overvoltage occurred in the output.
- **E-26**: Dropped voltage occurred in the output.
- **E-28**: Direct current overlapped with the output current.
- **E-29**: An earth fault has occurred.
- **E-30**: Booster circuit is functioning improperly.
- **E-31**: Earth-fault detecting circuit is functioning improperly.
- **E-35**: Thermal fuse has blown.
- **E-37**: An error occurred in the booster circuit.
**Additional Error Codes:**
- **E-43**: Error occurred in the booster circuit.
- **E-44**: Default setting(s) is faulty.
- **E-64**: Overcurrent occurred in the inverter circuit.
- **E-66**: Overvoltage occurred in the output (at high level).
