Class 2 Status
Codes
Status codes of class 2 are typically tempo-
rary. Their cause lies in the grid.
The first reaction of the inverter is to disconnect from the grid. Subsequently, the grid will
be checked for the duration of the observation period stipulated. If after the end of this pe-
riod no further defect is identified, the inverter resumes operating and feeding power into
the grid.
Behavior Grid conditions are thoroughly tested and as soon as they are
again within the permissible range, the inverter will resume
feeding power into the grid.
Remedy Check grid connections and fuses
Should the status code persist, you should contact your system
installer

General grid error
This error is always displayed first for grid errors. After reviewing all power stage sets, the
grid error is specified in more detail: 1x1 / 1x4 or the display remains at "109" (e.g., when
2 phases report "104" and one phase "101")
Behavior Grid conditions are thoroughly tested and as soon as they are
again within the permissible range, the inverter will resume
feeding power into the grid.
