Verdict (R14 page). Status: GATED — remains a process scaffold. Decision count: 6 (1 confirmed, 4 pending, 1 disclosed-none). Equipment (model/family): CATL EnerC (C&I BESS family); Sungrow PowerTitan2.0 (utility ESS, 2.5 MW / 5 MWh container, DC 1500 V) + SH5/6/8/10/12T residential hybrid (1000 V PV max, 16 A input, IP65) + SBR064-256 (3.2 kWh per LFP module, 6.4-25.6 kWh); Huawei LUNA2000-200KTL + SmartLi (FusionSolar); Deye SUN-5/6/8/10/12/15/20/25K-SG01HP3-EU-AM2 (160-700 V battery, 50 A charge/discharge) + BOS-G (51.2 V / 100 Ah / 5.12 kWh per module, 19-inch rack, >6000 cycles). BMS sensor: family-level for these models; exact P/N + OEM service manual revision recorded on PSR-CD-PV-05 (e.g. Sungrow BMS-board P/N per SH5-12T Service Manual rev. ≥2024-Q3; Huawei SmartLi BMS slave-board P/N per FusionSolar SmartLi Service Manual rev. ≥2023-Q4). Location: CN consolidation hub → sea port (origin → transit → destination). Horizon: T-72h → T+arrival (≈72 h pre-load + sea transit). Evidence date: 2026-09-22. Limitation: no CE / UKCA / FCC / UL certificate is held or displayed on this page for a specific unit; torque and validation values are OEM-manual-dependent and not published until the OEM service manual revision is recorded on PSR-CD-PV-05.

Torque (Step 4) and validation thresholds (Step 5) are OEM-manual-dependent: defaults below, final values recorded on PSR-CD-PV-05.
| Step# | Action | Owner | Input | Output | Done-when |
|---|---|---|---|---|---|
| 1 | Detect BMS fault from telematics or pre-loading inspection at the CN hub. | Pre-shipment QC Lead | Telematics feed + PSR-IN-QC-01 | Fault Triage Note (PSR-NT-FTN-02) | Triage note countersigned; corridor segment (origin | transit | destination) assigned. |
| 2 | Quarantine the unit; isolate the HV battery string per OEM LOTO. Default: Sungrow PowerTitan2.0 DC bus ≤1500 V; Sungrow SH5-12T PV ≤1000 V / battery 150-850 V; Deye SUN-5-25K-SG01HP3 battery 160-700 V; Deye BOS-G module 51.2 V.

Only if the unit has been pulled out of the consolidation flow and is treated under the documented service-bay workflow (Steps 1–5). After gate-in at the origin terminal the safe options are (a) delay booking until post-service validation is complete, or (b) trigger a destination-side swap on arrival via the Aftermarket Coordinator. Sea-transit swaps are out of scope for R14.
The Post-Service Validation Report (PSR-RP-PSR-09) closes out the task. It is countersigned by the Service Engineer and the Validation Engineer and referenced inside the Updated Route Dossier (PSR-DS-RD-10) before the unit is re-packed.
The Documentation Lead re-issues the commercial invoice and packing list so the post-service configuration matches the line-item description, and attaches the post-service validation report ID. Where lithium is present, the relevant MSDS / UN 38.3 test summary (per the UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7) is re-attached with the updated serial-number list.
Typical UN numbers for lithium-ion are UN 3481 (contained in equipment) or UN 3536 (packed with equipment). Confirm against the UN Manual of Tests and Criteria (ST/SG/AC.10/11/Rev.7, Part III, Subsection 38.3) using the OEM cell test summary, the IATA DGR, and the IMO IMDG Code for sea.
Stop. The Service Engineer escalates to the OEM distributor before any swap. The Parts Verification Card (PSR-CD-PV-05) is the gate — it must show OEM P/N, lot, OEM service manual revision, and destination-country conformity regime with named issuer + certificate ID before Step 4 begins.
