AI DIAGNOSIS — INV-02CRITICAL
INV-02 · DC voltage channel fault (2021)
DC voltage reads 0 from 2021-05-28 to 2021-11-15 (973 h) while string currents track normally — a DAQ/voltage-channel fault, not an outage; ≈3.2 MWh of output is invisible in the V×I power record (the 2021 efficiency step-down).
Recommended action
Verify the INV-02 DC-voltage transducer and wiring; re-integrate string-current-derived power into the record.
