reports

c2 drafted · lead Boost capacitor overvoltage

has_event_class

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

has_production_effect

c4 drafted · lead Trip (production stops)

Implied because the inverter must be restarted.

review note: support check: partial - The row requires an inverter restart, which implies stopping, but production stop is not stated.

has_recovery

c5 drafted · lead Manual reset (operator restarts or acknowledges)

First a delayed AC/DC power cycle; contact service if the fault remains.
