Import LFP 20kWh Wall Battery from China to Ukraine — Duplex Solar Use-Case, TCO & Landed Cost
Verdict (read first): Not yet quotable. On the declared scenario (one LFP wall-mounted 20kWh battery, China → Ukraine, duplex solar use-case, 10-year horizon, 8.00% discount, USD 6,000 landed CapEx, USD 0.10/kWh self-consumption tariff, USD 0.012/kWh charge cost, 2.00% annual degradation, 95% usable SoC, 6,300 kWh Year-1 throughput), the scenario model returns NPV = -USD 6,069.75, discounted payback = None, simple payback = None, and LCOS = USD 0.1681/kWh. Costs dominate benefits in every year of the horizon; the project is cash-negative on this tariff. As-of 2026-09-21; Ukraine import duty and VAT lines remain PENDING — UKTZED portal lookup. This page is a model scaffold, not an offer.

| Year | Cost (USD) | Benefit (USD) | Net (USD) | Discount factor | Discounted net (USD) | Energy (kWh) |
|---|---|---|---|---|---|---|
| 0 | 6,000.00 | 0.0000 | -6,000.00 | 1.00 | -6,000.00 | 0.0000 |
| 1 | 80.00 | 82.17 | 2.17 | 0.9259 | 2.01 | 6,300.00 |
| 2 | 81.60 | 80.53 | -1.07 | 0.8573 | -0.9170 | 6,174.00 |
| 3 | 83.23 | 78.92 | -4.31 | 0.7938 | -3.42 | 6,050.52 |
| 4 | 84.90 | 77.34 | -7.56 | 0.7350 | -5.55 | 5,929.51 |
| 5 | 86.59 | 75.79 | -10.80 | 0.6806 | -7.35 | 5,810.92 |
| 6 | 88.33 | 74.28 | -14.05 | 0.6302 | -8.85 | 5,694.70 |
| 7 | 90.09 | 72.79 | -17.30 | 0.5835 | -10.09 | 5,580.81 |

| 10 | 95.61 | 68.51 | -27.10 | 0.4632 | -12.55 | 5,252.61 |
Reading the table: Year 0 is the full landed CapEx (USD 6,000). Annual costs inflate at 2.0%/yr from a USD 80 Year-1 base. Benefits are computed on throughput × RTE × self-consumption tariff (USD 0.10/kWh), with throughput degrading at 2.00%/yr and the usable SoC held at 95%. Both simple and discounted paybacks are "—" because cumulative net cash flow never turns positive on these inputs. LCOS = PV(costs) ÷ PV(energy to load) = USD 6,580.49 ÷ (sum of discounted energy rows where energy is counted to load) = USD 0.1681/kWh (computed result).
6. Sensitivity — payback years vs. self-consumption tariff (USD/kWh)
| Tariff (USD/kWh) | Annual avoided import (USD/yr, Year 1) | Annual net benefit (USD/yr, Year 1) | Simple payback (years) | Discounted payback (years) |
|---|---|---|---|---|
| 0.08 | 504.00 | 424.00 | None (15.7+) | None |
| 0.10 (base) | 630.00 | 550.00 | None | None |
| 0.12 | 756.00 | 676.00 | 9.9 | None |
| 0.15 | 945.00 | 865.00 | 7.4 | 9.7 |
| 0.20 | 1,260.00 | 1,180.00 | 5.4 | 6.6 |
| 0.25 | 1,575.00 | 1,495.00 | 4.3 | 5.0 |

11. FAQ
What is the TCO verdict for this use-case?
NPV = -USD 6,069.75 over a 10-year horizon at 8.00% discount. Simple and discounted payback are "—" (none) because cumulative net cash flow never turns positive at USD 0.10/kWh self-consumption tariff and USD 6,000 landed CapEx. LCOS = USD 0.1681/kWh. Verdict: NOT YET QUOTABLE.
What HS code applies to a 20 kWh LFP wall battery imported into Ukraine?
The exact Ukraine national HS line (UKTZED) for lithium-ion storage batteries of this capacity must be confirmed against the State Customs Service of Ukraine UKTZED portal (https://customs.gov.ua/en/) on the transaction date. The line is marked PENDING — lookup in §9.
Does this TCO include Ukrainian import duties and VAT?
No. Ukrainian import duty rates and import VAT treatment are marked PENDING — lookup against the UKTZED portal on 2026-09-21. The computed cash flow uses a USD 6,000 placeholder CapEx; replace with a duty/VAT-inclusive landed CapEx before procurement use.
Are the payback and sensitivity figures quoted prices?
No. Payback and sensitivity outputs are labelled ILLUSTRATIVE — NOT A QUOTE. They use placeholder inputs for buyer modelling only and do not constitute a TradVolt offer or contract.
Which certifications should a buyer request from the OEM?
At minimum: IEC 62619 (IEC publication page), UN 38.3 (UN Manual of Tests and Criteria), CE/EMC (EUR-Lex EMC Directive), and any Ukraine-specific conformity evidence. Specific certificate numbers and issuing bodies must be supplied by the OEM per shipment.
What is the use-case scope of this analysis?
One duplex solar installation in Ukraine paired with one LFP wall-mounted 20 kWh battery, daily cycling to maximise self-consumption. PV array sizing, hybrid inverter selection, and grid-tie approval fees are out of scope unless explicitly listed.
Can the CapEx/OpEx lines be sent as a structured RFQ?
Yes. Use the Request Quote form above (POSTs to /rfq/). Replies are provided in 48h on business days. Include product_sku (LFP-WALL-20KWH), quantity and unit, incoterm, target certification, destination country (Ukraine), buyer email and buyer company.
