Troubleshooting and error codes
| - Error code | Name of Alarm and Cause | Solution |
|---|---|---|
| E084 BackFeed OC Yellow LED |
Return current to photovoltaic field: The error occurs if the input voltage is particularly low (typically in the evening in conditions of low irradiation) and indicates a return current from the inverter to the photovoltaic panels. | If the error occurs in the evening or in conditions of low irradiation, it must not be considered a problem but a protection intervention for the photovoltaic field. If the error occurs with good irradiation conditions, switch the inverter off and back on again; if the error persists, contact customer assistance. |

Error battery pack 1 unusable: Indicates that the battery pack is unusable and must be replaced. | • Error inside battery pack 1 and cannot be checked externally. • If the problem (once the system has been switched off and back on) persists, contact customer assistance. |
| E087 - Batt. 2 - F2 No LED |
Error battery pack 2 unusable: Indicates that the battery pack is unusable and must be replaced. | • Error inside battery pack 2 and cannot be checked externally. • If the problem (once the system has been switched off and back on) persists, contact customer assistance. |
