STRING DROP CRITICAL — INV-03 / MPPT-2 / SC-2
String-level underperformance at INV-03 / MPPT-2 / SC-2.
Evidence
- SC-2 current is 36% below peer strings on INV-03 MPPT-2 for three intervals.
- 1 related occurrence are active.
Probable causes
- Loose or damaged DC connector
- Partial shading, module damage, or bypass-diode activation
- String fuse or wiring resistance
Recommended field action
Inspect string harness and combiner; compare IV curve on affected string.
- Owner
- om engineer
- Timeframe
- immediate
Verify recovery
After repair, compare string current with peer strings at the same irradiance for at least two polling intervals.
Safety: Isolate DC, follow lockout-tagout, and verify absence of voltage before opening connectors.
