`has_event_class`

c5 drafted · lead Fault (device stops or needs intervention)

Implied by the inverter reconnecting to the grid afterward.

STPxx-US-50-BE-en-14 sec=h507 h=90e3985f0ea6

review note: support check: partial - Reconnecting to the grid implies a disconnect, but fault classification is not clearly stated; weakly implied.
