Verdict. This page is a bounded BENEFIT ILLUSTRATION only — NOT a quote, NOT an computed TCO. Per the scenario model run on the bounded inputs declared in §5, the 10-year self-consumption-offset benefit stream gives NPV = €2,166.34 at a discount rate of 8.00% over a 10-year horizon, with discounted payback = 0.0 years, simple payback = 0.0 years, and LCOS = €0.0000 / kWh. Because CapEx, OpEx, replacement reserve, residual value and per-kWh charging cost are all DROPPED-ITEM inputs in this run, the cost side is €0.0000 in every year and the page does not present NPV, payback or LCOS as computed TCO figures. Equipment family: 10 kWh wall-mounted LFP residential battery — cell basis EVE Energy LF304 (3.2 V / 304 Ah prismatic LFP, per EVE evemall product page); module references for EU shipment Sungrow SBR064-256 family and Huawei LUNA2000-5/10/15-S0 family. Destination: Slovenia (SI), port of entry Koper. Horizon: 10 years. Evidence-date (page): 2026-09-22. Limitation: all cost lines are DROPPED-ITEM; binding figures require a populated RFQ.

NPV, payback and LCOS are therefore NOT an computed TCO and must not be read as landed-cost numbers. No certificate numbers, no notified-body IDs, no customs rates and no VAT rates are published on this page. Binding figures require a populated RFQ. |
B2B reference page for European solar installers, EPCs and villa-scale project buyers sourcing a 10 kWh wall-mounted LFP residential battery from China. Cell chemistry basis: EVE Energy LF304 (3.2 V / 304 Ah prismatic LFP). Module reference families for EU shipment: Sungrow SBR064-256 and Huawei LUNA2000-5/10/15-S0. This page is a bounded benefit illustration under explicit assumptions — not a quote, not an computed TCO.
The reference use case is a Slovenian single-family villa with an existing or planned rooftop PV system (typical residential PV size band 6–10 kWp), seeking one wall-mounted 10 kWh LFP battery module for self-consumption optimisation, backup reserve and demand-charge avoidance. The 10 kWh figure corresponds to one fully populated wall module with integrated BMS (per OEM datasheet); expansion via parallel units is out of scope of this single-page benefit illustration. The cell basis for the reference LFP chemistry is the EVE Energy LF304 prismatic cell — 3.2 V nominal / 304 Ah nominal / 4000 cycles at 25 °C to ≥ 80% capacity retention / 173.7 × 71.7 × 207.2 mm / 5450 g (per EVE evemall product page). The 10 kWh module families referenced for EU shipment are the Sungrow SBR064-256 range (3.2 kWh per LFP module, 6.4–25.6 kWh per unit across 2–8 modules, 30 A max charge/discharge, 100% DoD usable, per Sungrow product page) and the Huawei LUNA2000-5/10/15-S0 family (5/10/15 kWh stackable modules, per Huawei FusionSolar product page).

The "Cost" column is €0.0000 in every year because all CapEx, OpEx, replacement and residual-value inputs are DROPPED-ITEM in this model run. The "Benefit" column is the self-consumption-offset stream valued at the populated asset.ess.value_per_kwh_discharged input and decays year-on-year in line with the populated degradation assumption encoded in the model. Discount factor = 1 / (1 + 0.08)year. Discounted net = Net × Discount factor. The horizon is 10 years; rows are inclusive of year 0 (capex year) and year 10. Because Cost = 0 in every year, simple payback = 0.0 and discounted payback = 0.0; this is an artefact of the benefit-only model run and is not a procurement-grade payback number.

No. This page is a bounded BENEFIT ILLUSTRATION only. NPV, payback, IRR and LCOS figures on this page were produced by Tradvolt's scenario model from the bounded assumptions stated in §5 (10-year horizon, 8.00% discount rate, self-consumption-offset benefit only). All CapEx, OpEx, replacement reserve, residual value, customs duty, VAT and per-kWh charge-cost inputs are DROPPED-ITEM in this run; the cost side is €0.0000 in every year, which makes NPV = PV of benefits, payback = 0.0 and LCOS = €0.0000/kWh. These figures MUST NOT be read as a procurement-grade landed-cost TCO. Binding figures require a populated RFQ via /rfq/.
Importers must verify the exact HS national line on the EU TARIC consultation tool (https://ec.europa.eu/taxation_customs/dds2/taric/taric_consultation.jsp?Lang=en). Classification depends on cell chemistry, configuration (cells vs. module with BMS) and end-use. A Binding Tariff Information (BTI) ruling from the Slovenian customs authority is the only legally binding classification.
No certificate numbers or notified-body IDs are published on this page. The standards table in §2 lists the designation, edition and scope only (Regulation (EU) 2023/1542; IEC 62619:2022 Edition 2; IEC 62485-5:2020; UN 38.3 / ST/SG/AC.10/11/Rev.7; IATA DGR; ICC Incoterms 2020). Certificate numbers and issuing notified body IDs must be supplied per shipment against the underlying test report before any EU conformity claim is asserted.
Sea freight Shenzhen → Koper typically takes 28–40 days port-to-port; rail via Duisburg and onward road transit to SI is typically 18–25 days. Final lead time depends on the chosen Incoterm (ICC Incoterms® 2020 — https://iccwbo.org/business-solutions/incoterms-rules/incoterms-2020/), port congestion and customs clearance at the SI port of entry.
Lithium-ion batteries are assigned to UN 3480 (lithium batteries) or UN 3481 (lithium batteries packed with or contained in equipment) depending on configuration, and must follow the IATA Dangerous Goods Regulations (IATA DGR — https://www.iata.org/en/programs/cargo/dgr/) for air or the IMDG Code for sea. A UN 38.3 test summary (UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7 — https://unece.org/transport/dangerous-goods/un-manual-tests-and-criteria) is required per cell/battery type. The freight forwarder confirms the exact UN number and packing instruction per shipment.
The current Slovenian VAT (DDV) rate is not hardcoded on this page and must be confirmed on the Slovenian Financial Administration (FURS) portal (https://www.fu.gov.si/) at the time of import. No VAT line is populated in the model run on this page.
