4 Errors, Disturbances, Warnings SMA Solar Technology AG 4 Errors, Disturbances, Warnings 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 11 SMA Solar Technology AG 4 Errors, Disturbances, Warnings Message Cause and corrective measures ACVtgRPro The ten-minute average line voltage is no longer within the permissi- ble range. The line voltage or grid impedance at the connection point is too high. The inverter disconnects from the utility grid to com- ply with the power quality.
- Page 12 4 Errors, Disturbances, Warnings SMA Solar Technology AG Message Cause and corrective measures Fault current The inverter has detected a change in the differential current. A change in the differential current can be caused by a ground fault, dI-Srr residual current or a malfunction. The inverter disconnects from the utility grid.
