IMPORTANT!
Active PV module electronics (e.g., power optimiser) can impair the function of
the Arc Fault Circuit Interrupter. Fronius does not guarantee that the Arc Fault
Circuit Interrupter will work correctly in combination with active PV module
electronics.
Reconnection behaviour
After detection of an arc, feeding energy into the grid is interrupted for at least 5
minutes. Depending on the configuration, feeding energy into the grid is then
automatically resumed. If several arcs are detected within a period of 24 hours,
feeding energy into the grid can also be permanently interrupted until a manual
reconnection has taken place."
