Answer / verdict (first 100 words): This SOP is applicable to a defined, named vertical-solar BoS kit: Sungrow SG5K-D / SG8K-D / SG10K-D single-phase string inverters paired with Trina Vertex N NEG9RC.27 bifacial modules and/or LONGi Hi-MO 7 LR7-54HBB modules, plus an ABB S900-G T1/T2 DC combiner, ABB OVR PV 40 1000 P Type 1+2 DC surge protection and K2 Systems MultiRail aluminium vertical mounting. It is not a generic BoS SOP. Horizon: CN→GE lane, indicative 10 working days from a complete RFQ. Evidence date stamp: 2026-09-22. Limitations: HS codes and Georgian import-duty/VAT rates are placeholders (PENDING — lookup on the RS.GE official portal); CE Technical File is procedural evidence, not a market-surveillance guarantee; torque, SOC and isolation voltages must be re-checked against the OEM manual revision listed below on the date of inspection.
| Scope element | Decision |
|---|---|
| Applicable equipment | Sungrow SG5K-D / SG8K-D / SG10K-D inverters; Trina Vertex N NEG9RC.27 modules; LONGi Hi-MO 7 LR7-54HBB modules; ABB S900-G DC combiner; ABB OVR PV 40 1000 P Type 1+2 DC SPD; K2 Systems MultiRail aluminium vertical mounting structure |
| Corridor / location | China → Georgia (CN→GE), via Poti/Batumi sea or Tbilisi air |
| Horizon / duration | 10 working days indicative from a complete RFQ; subject to OEM evidence turnaround and RS.GE portal availability |
| Evidence-date stamp | All cited documents accessed 2026-09-22 |
| Key limitation | HS/duty block is a PENDING — lookup placeholder against RS.GE; no hardcoded rates |
| Applicable directives | LVD 2014/35/EU, EMC 2014/30/EU, RoHS 2011/65/EU (+ Machinery 2006/42/EC where mounting system is treated as machinery) |
The procedure covers the documentary package required to demonstrate CE conformity for a defined vertical-solar Balance-of-System kit before goods are loaded for the CN→GE lane:
Procedures with technical limits (AQL, torque on module/mid-clamps, maximum system voltage, MPPT voltage window, isolation/battery interfaces where present) MUST be re-read against the OEM manual revision named in §3 before any inspection, packing or commissioning activity. The revisions stated here are the minimum reference set; later OEM revisions supersede.

Model assumption: the manual revisions stated above (e.g., "UM-Ver.1.7", "Rev. A (2023)", "2024 datasheet edition") are the latest OEM revisions TradVolt has on file as of 2026-09-22; the Documentation Desk must reconfirm the current revision with the supplier at the moment of inspection and update the OEP accordingly. The named OEM portals (Sungrow, Trina, LONGi, ABB, K2 Systems) are the authoritative source for the current datasheet / manual PDF — deep PDF paths on those sites are JS-rendered and must be pulled at RFQ intake.

Any change to the named equipment (e.g., inverter variant, module family, combiner swap, SPD swap, mounting-system substitution), the directive/standards set, or the corridor (CN→GE) requires a new revision of this SOP, re-approval by the Compliance Lead, and a delta review against the active Technical File index.
