Service class 2
Service class 3
Class 3 includes status codes that may occur while feeding energy into the grid, but gen-
erally do not cause the process to be interrupted for any length of time
The inverter disconnects automatically from the grid, the grid is then monitored as specified
and the inverter attempts to resume feeding energy into the grid.
