System Fault & Error Messages
| Operational Message | Message Meaning | Description |
|---|---|---|
| Isolation Fault | Isolation failure | Earth fault on the solar panels or failure of surge protection |
| Ground I Fault | GFCI active | Leakage current to ground is too high |
| Grid Fault | Grid failure | Grid measured data is beyond the specification (voltage & frequency) |
| No Utility | No utility | Utility is not available |
| PV Over Voltage | Input voltage too high | Input voltage from the solar panels higher than the max input voltage |
Inverter Fault & Error Messages
| Operational Message | Message Meaning | Description |
|---|---|---|
| Consistent Fault | Consistent failure | The readings of 2 microprocessors are not consistent. CPU and/or other circuit not functioning may be the cause |
| Over Temperature | Temperature too high | The internal temperature is higher than the normal value |
| Relay Failure | Output relay failure | The relay between the inverter and grid is not functional |
| DC INJ High | Output DC injection too high | Output DC injection is too high |
| EEPROM Failure | EEPROM problem | EEPROM inside the inverter has a data access problem. |
| SCI Failure | Problem with communication between microprocessors | The communication between MCU inside the inverter is abnormal |
| High DC Bus | DC bus voltage is too high | The DC Bus inside is higher than expected |
| Low DC Bus | DC bus voltage is too low | The DC Bus inside is lower than expected |
| Ref 2.5V Fault | 2.5V reference voltage inside problem | The 2.5V reference inside the inverter is abnormal |
| DC Sensor Fault | Output DC sensor abnormal | The DC output sensor is abnormal |
