Decoded

Reports string reverse current; look at PV array; confirm with string current measurement; do: string isolation, string configuration correction, inverter restart, contact manufacturer service.

What can be behind String reverse current

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

c3 drafted · lead String reverse current

c4 drafted · lead PV array

detected_by

c5 drafted · lead String current measurement

review note: support check: partial - Row says use a meter to find the abnormal string, but does not say it measures string current.

mitigated_by

c6 drafted · lead String isolation

c7 drafted · lead String configuration correction

c8 drafted · lead Inverter restart

c9 drafted · lead Contact manufacturer service

has_production_effect

c10 drafted · lead Trip (production stops)

Protection fault; restart required after the alarm clears implies the inverter stopped.

review note: support check: partial - Restart is required after the fault, implying a stop, but a trip is not explicitly stated for this row.

has_recovery

c11 drafted · lead Manual reset (operator restarts or acknowledges)

Wait for alarm to clear, then switch cycle and restart; if persistent, isolate and fix strings, then service.
