Tradvolt · CN→World green-tech export · Use-case TCO Brief
Vertical LFP (LiFePO₄) wall-mount battery in the 15 kWh energy class · Export route: China → Ghana · Use-case: salon backup in a low/medium grid-reliability setting.
Verdict (20-year horizon, Ghana destination, China origin, evidence dated 2026-09-21): No numeric landed-cost per unit is published on this page because the scenario model ran with explicit bounded defaults — every CapEx line item (battery unit, BMS, install labour, freight, duty, etc.) was marked DROPPED-ITEM and the model therefore returns no CapEx-driven payback. The model still produces a benefits-only NPV of USD 4,479.33 over 20 years at an 8.00% discount rate on a degradation-fading benefit stream; simple payback = 0.0 yr, discounted payback = 0.0 yr, LCOS = USD 0.0000/kWh (no cost denominator supplied). Treat these figures as the model output for the placeholders disclosed below; the next required step is to submit the RFQ so a real delivered-Ghana unit price, freight quote and HS-line-confirmed duty stack can replace each DROPPED-ITEM input.

DROPPED-ITEM. The benefit stream (8,689.03 undiscounted; 4,479.33 discounted) and the energy stream (4,050 kWh in year 1 fading to 2,758.99 kWh in year 20) are the only non-zero inputs the draft supplied. Replacing the DROPPED-ITEM inputs with RFQ numbers will lift the cost column and re-compute NPV / payback / LCOS automatically.

Cells left blank intentionally: no numeric payback is published until the OEM unit price, freight, broker fee and GRA-confirmed duty stack are quoted via RFQ; the scenario model already returned 0.0 yr when costs = 0, which is a degenerate result, not a real payback.

Equipment identity is fixed (Pylontech US5000 — OEM legal entity Pylontech Technologies Co., Ltd.). Datasheet PDF and pre-shipment certification PDFs are released by Tradvolt only after RFQ triage to confirm scope of supply; they are not surfaced as anonymous direct downloads.
The scenario TCO model did not receive the following inputs from the draft; they are recorded here as explicit bounded defaults (DROPPED-ITEM where applicable) and not as sourced facts.
opex.fixed = DROPPED-ITEM (no $/year preventive-maintenance line was supplied).residual_value.amount = DROPPED-ITEM; residual_value.year = DROPPED-ITEM (no end-of-horizon salvage figure supplied).capex[0].amount … capex[7].amount = DROPPED-ITEM (battery unit, BMS, install labour, cabling/breaker kit, permit, freight CN→Tema, broker fee, duty stack — all blanks).asset.ess.usable_pct = DROPPED-ITEM. OEM datasheet uses 90% DoD for cycle-life rating; usable DoD for backup duty is a buyer input.asset.ess.round_trip_eff = DROPPED-ITEM; OEM-datasheet candidate value ≈ 95% on DC side (Pylontech US5000 datasheet V1.6).asset.ess.cycles_per_year = DROPPED-ITEM. Implied by the energy stream 4,050 kWh / yr ÷ 14.4 kWh ≈ 281 cycles/yr if discharged every day; year-on-year fade to 2,758.99 kWh ≈ 192 cycles/yr by year 20 matches an LFP degradation rate consistent with Pylontech cycle-life curve.asset.ess.degradation_pct_per_year = DROPPED-ITEM. Model fits a fade consistent with ~2% per year on the implied energy stream above (label as model assumption, not OEM-stated).asset.ess.charge_cost_per_kwh = DROPPED-ITEM.asset.ess.value_per_kwh_discharged = DROPPED-ITEM. Year-1 benefit USD 522.82 / 4,050 kWh ≈ USD 0.1291/kWh; year-20 value/kWh ≈ USD 0.1291/kWh (consistent with the fade schedule above). Treat 0.1291 as the implicit model assumption, not as a sourced tariff.

Candidate classification is HS 8507.60 (lithium-ion accumulators, including LFP) per USITC HTS 2026 and WCO HS 2022. The national Ghana HS line, import duty, VAT, NHIL, GETFund, ECOWAS/AfCFTA levies, inspection fee and excise status are all PENDING — lookup on the GRA tariff portal (https://gra.gov.gh/tax-tariff/) and the Ghana National Trade Portal HS-code search (https://www.ghanatrade.gov.gh/hs-code-search). A licensed customs broker must confirm before commitment.
The scenario model ran with every CapEx input (battery unit, freight, duty, install labour, broker fee) marked DROPPED-ITEM. The model therefore returns 0.0 yr simple payback and 0.0 yr discounted payback, and NPV = USD 4,479.33 from the benefit stream only. Replace the DROPPED-ITEM CapEx inputs with the RFQ-returned unit price + freight + duty stack to obtain a meaningful payback and LCOS.
Yes. The OEM datasheet PDF (Pylontech US5000 V1.6) is released by Tradvolt after RFQ triage (no anonymous direct download); submit the RFQ form on this page for a 48h response on pricing, lead time and Incoterm.
Per ICC Incoterms® 2020 (ICC Publication No. 723E), CIF Tema is the common default for buyers who want the seller to insure and clear at destination port; FOB Shanghai is typical for buyers who self-arrange ocean freight and insurance; DAP Tema lands duty-unpaid to the buyer's named place. Marine insurance under CIF is conventionally 0.3%–0.5% of CIF value (ICC A5/B5).
Method note: every numerical line labelled PENDING — lookup or DROPPED-ITEM must be replaced before commitment. TCO figures (USD 4,479.33 NPV; simple payback 0.0 yr; discounted payback 0.0 yr; LCOS USD 0.0000/kWh; benefits USD 8,689.03 undiscounted, USD 4,479.33 discounted) are reproduced verbatim from the scenario TCO model of 2026-09-21 and are not adjustable by editorial commentary.
