Decoded

Reports insufficient DC input power, insufficient solar irradiance; look at PV array; do: string configuration correction.

What can be behind Insufficient DC input power

Failure modes that present as the reported condition, and the tests that tell them apart.

reports

c2 drafted · lead Insufficient DC input power

c3 drafted · lead Insufficient solar irradiance

affects

c4 drafted · lead PV array

has_event_class

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

review note: support check: partial - Feed-in is interrupted, but the passage does not say whether it is a fault or a warning.

has_production_effect

c6 drafted · lead Trip (production stops)

has_recovery

c7 drafted · lead Auto-reset (clears by itself)

Resumes when irradiation rises; if frequent, check array sizing and wiring

review note: support check: partial - Wait for higher irradiation implies resumption, but auto-reset is not explicitly stated.
