Debrief
The report was required to IEC TS 62446-3 classes, so every contact carries its anomaly class, delta-T and irradiance at capture.
The offline string had been missed by monitoring because its inverter averaged it against a healthy partner.
Twenty-three findings, each with a photo a contractor can find on site. That is what the owner pays for.
