B2B reference for procurement, EPC and project-finance teams evaluating a 2 MWh LFP container battery energy storage system (BESS) shipped from the People's Republic of China to the Republic of Korea for a solar-plus-storage use case. Tradvolt is the publisher of this reference page; the equipment referenced below is manufactured by named third-party OEMs. Currency: USD unless noted. Evidence date: 2026-09-21. Limitation: figures below are model output for an illustrative scenario and are not a Tradvolt offer or a binding landed-cost quotation. ILLUSTRATIVE — NOT A QUOTE.
For the illustrative 2 MWh LFP container BESS solar-plus-storage import scenario from China to the Republic of Korea over a 15-year horizon at a 7.00 % discount rate, the scenario model produces: NPV = −406,010.19 USD; discounted payback = none; simple payback = none; LCOS = 0.2193 USD/kWh; IRR = −0.0586. Total discounted PV of costs = 986,829.41 USD; total undiscounted costs = 1,184,215.67 USD; total undiscounted benefit = 933,074.44 USD; total discounted benefit = 580,819.22 USD. Equipment class = containerised LFP BESS, 20 ft ISO HC, liquid-cooled, 2 MWh DC; location = Jeolla / Chungcheong example site, KR; horizon = 15 years; evidence date = 2026-09-21; limitation = NPV is negative; simple and discounted payback are not reached within the 15-year horizon.

Interpretation: the modelled annual Benefit is positive in every operating year (1–15) but is outweighed in present-value terms by the Year-0 CapEx of 700,000.00 USD, producing a negative NPV of −406,010.19 USD. Cumulative discounted net cash flow remains negative at the end of the 15-year horizon, so simple payback and discounted payback are not reached and IRR is negative.

A container BESS may split-classify by component (cells 8507.60, PCS 8504.40, cabinet/switchgear 8537.10). The binding ruling is the Korea Customs Service line at the time of entry. The model in §4 does not include any specific duty line item; OpEx and CapEx lines are presented gross of duty for transparency.
ILLUSTRATIVE — NOT A QUOTE. The base case NPV is negative (−406,010.19 USD); cumulative discounted cash flow remains negative at the end of the 15-year horizon at any combination of the bounded inputs below, so simple and discounted payback are not reached.
| Avoided grid price (USD/kWh) ↓ / Annual throughput uplift ↑ | −10 % throughput | Base throughput | +10 % throughput |
|---|---|---|---|
| 0.09 USD / kWh | not reached (15 yr) | not reached (15 yr) | not reached (15 yr) |
| 0.11 USD / kWh | not reached (15 yr) | not reached (15 yr) | not reached (15 yr) |
| 0.13 USD / kWh | not reached (15 yr) | not reached (15 yr) | not reached (15 yr) |
Sensitivity interpretation: OpEx and discount rate held at the bounded values in §4.3; cells compare simple-payback outcomes across avoided-grid-price and throughput combinations. The conclusion follows from §4.2: under the bounded inputs declared in §4.3 the scenario model produces a negative NPV (−406,010.19 USD) and a negative IRR (−0.0586) for the 15-year horizon, so neither simple nor discounted payback is reached.
Tradvolt replies to verified RFQs within 48 business hours from the China desk (CST, UTC+8). All fields below are required for a binding landed-cost number. Tradvolt is the publisher of this reference page; the named OEM products are sourced from their respective manufacturers, and a quote issued against an RFQ names the OEM and SKU at the time of offer.
Korea Customs Service classifies lithium-ion cells under HS 8507.60 and assembled BESS cabinets / static converters typically under 8504.40 / 8537.10. Because a container BESS combines cells, BMS, PCS and switchgear, the national line must be confirmed against the Korea Customs Service HS-2022 schedule and the customs tariff notice in force as of 2026-09-21 before quotation. See the Duty-Stack block in §6.
Commonly referenced marks and standards include KC (Korea Certification) issued by KATS, IEC 62619:2022 ed2 for industrial LFP cells, IEC 62109-1:2010 / IEC 62109-2:2011 for PV power-converter safety, UL 1973 / UL 9540A for stationary and thermal-runaway tests, NFPA 855 for stationary ESS installation, and UN 38.3 (ST/SG/AC.10/11/Rev.7) for transport. Tradvolt does not hold certificates for any third-party OEM product referenced on this page; certificate numbers and the issuing CB / Notified Body must be verified against the chosen OEM datasheet.
No. All payback, NPV, IRR, LCOS and sensitivity numbers on this page are labelled ILLUSTRATIVE — NOT A QUOTE. They are reference arithmetic built from publicly cited inputs and bounded model assumptions, and are not a Tradvolt offer. A binding landed-cost number requires a current RFQ against a specific SKU and Incoterm.
Common FAK container routings from PRC ports such as Shanghai, Ningbo or Qingdao to Busan or Incheon. Actual transit time, free-time and BAF/CAF must be confirmed against the named carrier sailing schedule at booking; freight documents are issued per FIATA standard practice (see §2 reference URLs).
Incoterm selection is set by the buyer on the RFQ form (EXW, FOB, CFR, CIF, DAP, DDP) per ICC Incoterms® 2020 rules. Tradvolt will quote on any of these bases subject to a confirmed RFQ with destination postcode, the chosen OEM SKU, and any import VAT / deferred-duty declaration. Tradvolt is the publisher of this reference page and not the manufacturer of the named OEM products.
Warranty terms are set by the OEM (CATL EnerC, BYD MCube or Sungrow ST2752UX class). Operation outside the published SoC window, ambient envelope or duty cycle voids the warranty; refer to the OEM warranty letter for the chosen SKU.
