ESS Emergency-Stop Loop Test — Huawei LUNA2000-215-Series — Corridor CN→RO

Process/SOP · Huawei LUNA2000-215-Series LFP Energy Storage System · Issued 2026-09-21 · Owner: Tradvolt Service Engineering

Verdict (decision): The on-site E-stop loop test on the Huawei LUNA2000-215-Series LFP ESS delivered CIF/DAP to Romania is PASS when all of the following measured values meet the OEM service manual limits and the cited IEC clauses — (a) loop end-to-end resistance < 1.0 Ω; (b) control-circuit insulation resistance > 1.0 MΩ at 500 V DC; (c) contactor opening time ≤ 50 ms after E-stop press; (d) protective-equipment grounding ≤ 0.5 Ω; (e) manual reset only, with no automatic restart observed. Scope: vertical LFP cabinet Huawei LUNA2000-215-Series, CN→RO logistics corridor, dated evidence 2026-09-21, limitation: project-specific — values confirmed against the Huawei LUNA2000-215-Series OEM service manual revision on file.
