11.4.2 Error Numbers 01xx to 13xx - Disturbance on the Utility Grid

After a grid failure, the inverter monitors the utility grid for a specific period until it is reconnected.
If the inverter monitors the utility grid after a grid error, the grid monitoring time is maintained.
Certain errors, such as grid errors, cause the inverter to shut down. In this case, the instantaneous value TmsRmg indicates

the time during which the inverter monitors the electricity grid until it is reconnected. This grid monitoring time can be

defined in parameter GdErrTm.

Corrective

measures

The corrective measures specify measures that can help you

rectify the error.

Error no.
