Vertical-format lithium iron phosphate (LFP) battery racks (reference family: Pylontech US5000), ex-works China (CN) to project site in the Philippines (PH). This Standard Operating Procedure governs receiving inspection, initial torque verification, torque-mark application, and the post-commissioning re-torque pass.
Vertical LFP racks such as the Pylontech US5000 family are bolted assemblies; threaded joints on cell terminals, busbars, and rack-frame earth points can relax after shipment and initial thermal cycling. A documented torque-marking and re-torque SOP reduces the probability of joint loosening under vibration and thermal stress, supports warranty claims, and aligns with manufacturer service-manual instructions and applicable safety standards for stationary lithium-ion installations (e.g. IEC 62619:2022 ed2, IEC 62485-5:2020, UL 1973). Limitation: the Nm values, joint-counts, and re-torque intervals in this document are placeholders that MUST be replaced with values taken verbatim from the Pylontech US5000 Service Manual Rev2.0 (2023) before this SOP is released to site.
