Class 1 Status
Codes
The initial response of the inverter is to disconnect itself from the grid. The grid is subse-
quently checked for the stipulated monitoring period. If after the end of this period no fur-
ther defect is identified, your inverter resumes operating and feeding power into the grid.
IMPORTANT! The 2nd position x defines the exact network point for the following status
codes:
0 = several / all 3 phases
1 = L1
2 = L2
3 = L3

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.
