| Error Code | Description | Solution |
|---|---|---|
| No AC connection | No utility grid connected or utility grid power failure | This error would normally occur during a grid failure, if you still have electricity connected to your property then check your AC isolator or circuit breaker. If both the isolator and CB are ‘on’ and the problem persists submit a maintenance service request. |
| AC V outrange | Utility grid voltage is out of permissible range | This could happen particularly in the summer months if there is a lot of solar in your area, if the problem persists please submit a maintenance service request. |
| AC F outrange | Utility grid frequency is out of range | This could happen particularly in the summer months if there is a lot of solar in your area, if the problem persists please submit a maintenance service request. |
| Over temperature | Temperature out of range | Restart inverter. If still present, contact Growatt. NOTE: Ensure inverter is not covered causing the inverter to overheat |
| PV isolation low | Insulation problem | Submit a maintenance service request |
| Output high DCI | Output current DC offset too high | Restart the inverter. If the problem still persists submit a maintenance service request. |
| Residual 1 high | Leakage current too high | Restart the inverter. If the problem still persists submit a maintenance service request. |
| PV voltage high | DC input voltage is exceeding the maximum tolerable value | Disconnect DC switch immediately and switch off system. Submit a maintenance service request. |
| Auto test failed | Auto test failed | Restart the inverter and fault will clear. |
| 100 | Voltage fault | Submit a maintenance service request. |
| 101 | Communication fault | Turn off the DC switch and make the inverter totally shut down. Turn on the DC switch to see if the error still exists. If the error persists submit a maintenance service request. |
| 102 | Consistent fault. Data received by master and slave processor are different | Turn off the DC switch and make the inverter totally shut down. Turn on the DC switch to see if the error still exists. If the error persists submit a maintenance service request. |
| 116 | EEPROM Fault | When the inverter displays Error: 116, it means there is failure in reading or writing EEPROM. 1. Check when the error appears: if in the morning, if only in the morning, contact Growatt for support. 2. If the error appears all day; (a) restart the inverter, check if the error still exists. (b) If the fault is sustained, the control board needs to be replaced. Submit a maintenance service request. |
| 117 | Relay fault | There is something wrong with the relay circuit. Restart the inverter, if the problem still persists submit a maintenance service request. |
| 118 | Init model fault | Submit a maintenance service request. |
| 119 | GCFI device damage | Something may be wrong with the GCFI device inside the inverter. (a) Restart the invert for 2-3 times, check whether the error still exists. (b) If the error still exists submit a maintenance service request. |
| 120 | HCT Fault | When the inverter shows Error 120 it means something is wrong with the current sensor. Restart the inverter and if the error persists submit a maintenance service request. |
| 121 | Communication fault, master processor can’t receive data from slave processor | See error 101 and 102. |
| 122 | Bus voltage fault | Submit a maintenance service request. |
