Page 11: Troubleshooting
SMA Solar Technology AG 4 Troubleshooting Troubleshooting Error Messages Errors, disturbances and warnings are shown in the display and start in the first line with the word "Error", "Disturbance" or "Warning". In the second line of the display, the cause of the error, disturbance or warning is shown. - Page 12 4 Troubleshooting SMA Solar Technology AG Message Cause and corrective measure ACVtgRPro 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.
- Page 13 SMA Solar Technology AG 4 Troubleshooting Message Cause and corrective measure The inverter has detected a change in the differential current. A change in the differential current can be caused by a ground fault, Fault Curr-current control residual current or a malfunction. The inverter disconnects from the unit utility grid.
- Page 14 4 Troubleshooting SMA Solar Technology AG Message Cause and corrective measure Iac-DC_Offs-Srr Excessive DC current has been detected during feed-in operation. Iac-DC_Offs-Bfr Corrective measures: • Ensure that the grid conditions are complied with. • If this message is displayed frequently or recurrently, contact the SMA Service Line.
- Page 15 SMA Solar Technology AG 4 Troubleshooting Message Cause and corrective measure STM Timeout Internal program run disturbance Corrective measures: • If this message is displayed frequently, contact the SMA Service Line. Vac-Bfr The line voltage is no longer within the permissible range. The in- verter has disconnected from the utility grid for safety reasons.
