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.

Islanding detected
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 Should the status code persist, you should contact your system
installer
221
Grid voltage (L1/N) exceeds admissible limits
Behavior As soon as the grid voltage has returned to admissible range,
the inverter resumes feeding power into the grid.
Remedy Check grid voltage; if the status code persists you should con-
tact your electrical contractor
222
Grid voltage (L1/N) below admissible limits
Behavior As soon as the grid voltage has returned to admissible range,
the inverter resumes feeding power into the grid.
Remedy Check grid voltage; if the status code persists you should con-
tact your electrical contractor
223
Grid voltage (L2/N) exceeds admissible limits
Behavior As soon as the grid voltage has returned to admissible range,
the inverter resumes feeding power into the grid.
Remedy Check grid voltage; if the status code persists you should con-
tact your electrical contractor
