reports

c2 drafted · lead Grid overfrequency

has_event_class

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

review note: support check: partial - The passages show it is a listed fault code in the troubleshooting table, but they give no explicit fault-versus-warning classification.

has_production_effect

c4 drafted · lead Trip (production stops)

review note: support check: partial - The inverter reconnects after the grid returns to normal, which implies it disconnected, but the passages don't explicitly say production stops.

has_recovery

c5 drafted · lead Auto-reset (clears by itself)

Further checks only if the fault repeats.
