| Possible Cause | Suggestion |
| Cause ID = 1 The PV array is not properly configured.Excessive PV modules are connected in series to PV strings 1 and 2, and therefore the PV string open-circuit voltage exceeds the inverter maximum MPP voltage. |  |
| Cause ID = 2 The PV array is not properly configured.Excessive PV modules are connected in series to PV strings 3 and 4, and therefore the PV string open-circuit voltage exceeds the inverter maximum MPP voltage. |  |
| Cause ID = 3 The PV array is not properly configured. | |
