c2 drafted · lead Arc fault

has_event_class

c3 drafted · lead Fault (device stops or needs intervention)

review note: support check: partial - Code 242 needs an Enter reset and is an arc event, but the passages don't state a fault classification.

has_production_effect

c4 drafted · lead Trip (production stops)

Feed-in resumes only after acknowledgement, implying it is interrupted until then.

review note: support check: partial - The passages say the inverter restarts feeding after the reset, which implies feed-in was interrupted, but they don't say so explicitly.

has_recovery

c5 verified · fact Manual reset (operator restarts or acknowledges)

If it keeps recurring, contact the installer.
