Verdict: FM-EPS-002: Solar Array String Interconnection Loss
The deviation on solar_array_current matches the documented signature of FM-EPS-002 (Solar Array String Interconnection Loss): solar_array_current drops by a quantized ~33% step during a sunlit period. Observed telemetry confirms the signature: solar_array_current min 5.544, max 7.7, mean 6.622 A over the window. The recommended mitigation is SOP-EPS-102.

- Execute SOP-EPS-102 (Solar Array String Reconfiguration) as the primary corrective action for FM-EPS-002. cited
- Monitor solar_array_current until values return within limits and confirm recovery. cited
- If the condition persists, escalate to the on-call systems engineer for a contingency safe-mode decision. ungrounded — blocks release
