Verdict (first 100 words): 9 steps, ~5 working days (D0 → D0+5), on the CN→MA corridor for vertical-solar BoS projects using either a CATL EnerC outdoor liquid-cooled LFP cabinet (372 kWh class) or a Huawei LUNA2000-200/290/215 series Smart String ESS (200 / 215 / 290 kWh classes). All numeric limits below are model assumptions reproduced from the published OEM datasheets; the controlling values at execution are the service-manual revision physically shipped with the unit.

Scope: Standard Operating Procedure for the Site Acceptance Test (SAT) of Energy Storage System (ESS) equipment supplied under vertical-solar Balance of System (BoS) contracts on the China → Morocco import corridor.
Page type: Process / SOP. Audience: EPC contractors, site engineers, QC inspectors, logistics coordinators.
This SOP defines the on-site acceptance sequence for ESS units arriving from CN suppliers into Moroccan sites, ensuring that every unit meets the contractual and OEM performance envelope before commissioning.
This SOP is dimensioned against two public, commercially-marketed ESS cabinet families routinely shipped on the CN → MA corridor for vertical-solar BoS projects. Confirm the shipped SKU against its OEM service manual revision before executing §3 (limits below are SKU-specific; model assumptions until the RFQ pack returns the manual rev):
Numeric limits used in §3 are reproduced from the OEM datasheets for the two families above and treated here as the project's working envelope. They are flagged as model assumptions until cross-checked against the service-manual revision physically shipped with the unit.
