Class 3 status
codes
Class 3 comprises status codes that may
appear during feed-in operation and that do
not cause a permanent interruption of the
operation of feeding power into the grid.
After automatic disconnection from the grid and waiting for its conditions to return to those
stipulated, your inverter will try to resume feed-in operation.
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

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.
