The audited model prices the "value" of 1 kWh shifted through the battery at the Lithuanian grid import tariff of ~€0.28/kWh, but debits round-trip losses (~7 %) and an OpEx share against that same revenue line. Under the bounded assumptions above, the per-kWh net contribution is negative and never recovers within 25 years. If the buyer has a higher-value use case — e.g. avoided-outage payments, demand-charge reduction, or a time-of-use spread > €0.10/kWh — re-run the model with those inputs. The current page is a snapshot for the stated scenario only.

Over a 25-year horizon at an 8 % discount rate, the audited model returns NPV of −15,262.29 EUR, undiscounted total cost of 22,753.48 EUR, undiscounted total benefit of −2,440.27 EUR, and LCOS of 0.2655 EUR/kWh. Neither simple payback nor discounted payback is reached within 25 years because annual benefit is negative under the scenario inputs.
Yes. A stationery LFP energy storage system placed on the EU market must carry CE marking and meet the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU, supported by a Declaration of Conformity and technical file. Certificate numbers must be requested from the OEM for the exact SKU.
Lithuania applies the EU Common External Tariff. The duty and VAT lines on this page are marked PENDING — lookup because the exact HS subheading, preferential rate (if any), and Lithuanian VAT must be confirmed against the official EU TARIC database and the State Tax Inspectorate (VMI) before quoting.
CapEx is the ex-works unit price plus OEM accessories and on-site installation. Landed cost adds international freight, marine insurance, EU customs duty, Lithuanian VAT, terminal handling charges, customs broker fees, and last-mile delivery to the hotel site.
The reference product is marketed as stackable. Additional modules may be paralleled subject to the OEM's installation manual (Pylontech US5000 manual Rev. 1.9) and the rating of the hybrid inverter. Confirm maximum parallel count and BMS firmware compatibility with the OEM before ordering.
Typical set: commercial invoice, packing list, bill of lading or airway bill, Certificate of Origin (FORM EUR.1 or REX if a preferential rate applies), UN 38.3 test summary, MSDS, and the OEM's Declaration of Conformity. Final document set must be confirmed with your customs broker.
