Event Messages
Event number | Message, cause and corrective measures |
---|---|
101 102 103 | Grid fault The grid voltage or grid impedance at the connection point of the inverter is too high. The inverter has disconnected from the utility grid. Corrective measures:
|
202 203 | Grid fault The utility grid has been disconnected, the AC cable is damaged or the grid voltage at the connection point of the inverter is too low. The inverter has disconnected from the utility grid. Corrective measures:
If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator. The grid operator must agree with an adjustment of the voltage at the feed-in point or with a change of the monitored operating limits. If the grid voltage is permanently within the permissible range and this message is still displayed, contact Service. |
301 | Grid fault The ten-minute average value of the grid voltage is no longer within the permissible range. The grid voltage or grid impedance at the connection point is too high. The inverter disconnects from the utility grid to maintain power quality. Corrective measures:
|
401 402 403 404 | Grid fault The inverter is no longer in grid-parallel operation and has stopped feeding into the utility grid. Corrective measures:
|
501 | Grid fault The power frequency is not within the permissible range. The inverter has disconnected from the utility grid. Corrective measures:
|
601 | Grid fault The inverter has detected an excessively high proportion of direct current in the grid current. Corrective measures:
|
701 | Frq. not permitted > Check parameter The power frequency is not within the permissible range. The inverter has disconnected from the utility grid. Corrective measures:
|
1302 | Waiting for grid voltage > Installation failure grid connection > Check grid and fuses The inverter has detected an error in the AC cabling. The inverter cannot connect to the utility grid. Corrective measures:
|
1501 | Reconnection fault grid The changed country data set or the value of a parameter you have set does not correspond to the local requirements. The inverter cannot connect to the utility grid. Corrective measures:
|
3301 | Unstable operation > Generator output too low There is not enough power at the DC input of the inverter for stable operation. This may be caused by snow on the PV modules or insufficient irradiation. The inverter interrupts feed-in operation and can no longer connect to the utility grid. Corrective measures:
|
3302 | Unstable operation > Abort self-test There is not enough power at the DC input of the inverter for stable operation. This may be caused by snow on the PV modules or insufficient irradiation. The inverter interrupts feed-in operation and can no longer connect to the utility grid. Corrective measures:
|
3303 | Unstable operation > Data storage blocked There is not enough power at the DC input of the inverter for stable operation. This may be caused by snow on the PV modules or insufficient irradiation. The inverter interrupts feed-in operation and can no longer connect to the utility grid. Corrective measures:
|
3401 3402 | DC overvoltage > Disconnect generator Overvoltage at the DC input. This can destroy the inverter. Corrective measures:
If the DC voltage is below the maximum input voltage of the inverter, reconnect the DC connectors to the inverter. If the DC voltage is above the maximum input voltage of the inverter, ensure that the PV array has been correctly rated or contact the installer of the PV array. |
3501 | Insulation resistance > Check generator The inverter has detected a ground fault in the PV array. Corrective measures:
|
3601 | High discharge curr. > Check generator The leakage currents of the inverter and the PV array are too high. There is a ground fault, a residual current or a malfunction. The inverter interrupts feed-in operation immediately after exceeding a threshold and then automatically reconnects to the utility grid. If this process happens five times a day, the inverter disconnects from the utility grid and terminates feed-in. Corrective measures:
|
3701 | Resid.curr.too.high > Check generator The inverter has detected a residual current due to temporary grounding of the PV array. Corrective measures:
|
3801 3802 | DC overcurrent > Check generator Overcurrent at the DC input. The inverter briefly interrupts feed-in operation. Corrective measures:
|
3901 3902 | Waiting for DC start conditions > Start cond. not met The feed-in conditions for the utility grid are not yet fulfilled. Corrective measures:
|
6001-6438 | Self diagnosis > Interference device The cause must be determined by the Service. Corrective measures:
|
6501-6511 | Self diagnosis > Interference device The inverter has switched off due to excessive temperature. Corrective measures:
|
6512 | Minimum operating temperature not reached The inverter will only recommence grid feed-in once the temperature has reached at least −25°C. |
6603 6604 | Self-diagnosis > Overload The cause must be determined by the Service. Corrective measures:
|
6606 | Interference device The cause must be determined by the Service. Corrective measures:
|
6701 6702 | Communication disturbed The cause must be determined by the Service. Corrective measures:
|
6801 6802 | Self-diagnosis > Input A defective The cause must be determined by the Service. Corrective measures:
|
6901 6902 | Self-diagnosis > Input B defective The cause must be determined by the Service. Corrective measures:
|
7001 7002 | Sensor fault fan permanently on The cause must be determined by the Service. Corrective measures:
|
7101 | SD memory card defective The SD memory card is not formatted. Corrective measures:
|
7102 | Parameter file not found or defective The parameter file was not found or is defective. The update failed. The inverter continues to feed in. Corrective measures:
|
7105 | Param. setting failed Parameters could not be set using the memory card. The inverter continues to feed in. Corrective measures:
|
7106 | Update file defect. Update file on the memory card is defective. Corrective measures:
|
7110 | No update file found No update file has been found. Corrective measures:
|
7201 7202 | Data stor. not poss. Internal error. The inverter continues to feed into the utility grid. Corrective measures:

|
8101 8102 8103 8104 | Communication disturbed The cause must be determined by the Service. Corrective measures:
|
9002 | Installer code invalid The SMA Grid Guard code entered is incorrect. The operating parameters are still protected and cannot be changed. Corrective measures:
|
9003 | Grid parameter locked The parameters are now locked. You cannot change the parameters. Corrective measures:
|
9005 | Changing of grid parameters not possible > Ensure DC supply PV power is too low for setting the country data set. As soon as sufficient irradiation is available, the inverter assumes the setting automatically. |
