ILLUSTRATIVE — NOT A QUOTE. No specific OEM batch, EXW price, freight line, VAT line, or certification number is bound to the figures on this page. Numbers are produced by the Tradvolt scenario TCO model from the bounded inputs in the Assumptions section below. A binding quote requires a specific product datasheet, the OEM installation manual revision for the shipment, and EU TARIC lookup against HS 8507.60.

Assumptions (explicit bounded defaults)
These are model assumptions, not sourced facts. They are the inputs the scenario TCO model consumed to produce the tables above; changing any of them re-runs the model.
| Input | Value | Classification |
|---|---|---|
| horizon_years | 20 | model assumption |
| discount_rate | 8.00 % | model assumption |
| opex.escalation_pct | 2.0 % per year (applied to the EUR 80 base OpEx) | model assumption |
| residual_value.amount | EUR 0 (no end-of-life residual booked) | model assumption |
| residual_value.year | 20 | model assumption |
| asset.ess.usable_pct | 5 kWh nameplate usable (no DoD haircut applied at system level) | model assumption |
| asset.ess.round_trip_eff | 0.90 (AC-side throughput basis) | model assumption |
| asset.ess.cycles_per_year | 270 (≈ 5 kWh × 270 ≈ 1,350 kWh delivered in year 1) | model assumption |
| asset.ess.degradation_pct_per_year | 2.0 % capacity fade | model assumption |
| asset.ess.charge_cost_per_kwh | EUR 0.30 (grid charge cost used for throughput / float losses) | model assumption |
| Benefit tariff (diesel-equivalent displaced value) | EUR 0.1167 / kWh (used as the benefit tariff in the computed tables; not a diesel price quote) | model assumption |
| Initial CapEx (year 0) | EUR 2,898.00 (illustrative; excludes EU CET duty and Denmark VAT) | model assumption |
| Annual OpEx (year 1 base) | EUR 80.00 | model assumption |
Note on NPV = -2,456.85: undiscounted costs (EUR 4,841.79) exceed undiscounted benefits (EUR 2,617.59), so the project is not self-funding under these bounded assumptions. A binding quote may revise CapEx, benefit tariff, and cycling profile and would need to be re-run through the model.
CapEx — Capital Expenditure Breakdown (illustrative)
The CapEx figure of EUR 2,898.00 used as the Year 0 cost in the TCO tables is a model assumption (an illustrative landed cost for the Deye BOS-G 5.12 kWh LFP rack module per the OEM product page at Deye BOS-G product page). It is NOT a quote. Specific line items below are placeholders until an OEM datasheet for the specific batch and a freight quote are bound to the page.

Frequently Asked Questions
What HS code applies to LFP battery systems imported to Denmark?
LFP battery systems typically classify under HS code 8507.60 (lithium-ion accumulators). Confirm the exact national line via EU TARIC before importing.
What is the illustrative NPV for the Deye BOS-G 5.12 kWh telecom backup system in this TCO model?
Under the bounded assumptions on this page (8.00% discount rate, 20-year horizon, benefit tariff EUR 0.1167/kWh, 270 cycles/year, 2.0% capacity fade), the scenario TCO model returns NPV of EUR -2,456.85, with simple payback and discounted payback not reached within the 20-year horizon. These numbers depend on the model assumptions above and on the actual OEM product batch bound at RFQ.
Does Tradvolt handle Denmark customs clearance?
Tradvolt supports buyers with shipping documentation. Customs clearance is typically handled by the buyer's appointed broker or importer of record.
Is the TCO on this page a binding quote?
No. All figures on this page are ILLUSTRATIVE — NOT A QUOTE. No specific OEM batch, EXW unit price, freight line, EU CET duty, Denmark VAT, or certification number is bound to the figures here. Request a formal quote via the RFQ form for current pricing.
Can the Deye BOS-G 5.12 kWh rack system be paralleled for larger telecom sites?
The Deye BOS-G product family supports system sizes from 20.48 kWh to 61.44 kWh by paralleling 4-12 modules (per the OEM product page at Deye BOS-G product page). Confirm the parallel count, DC-bus limits, and BMS master/slave rules against the OEM installation manual revision supplied for the specific batch.
Does the EU Battery Regulation 2023/1542 affect this product?
Lithium battery systems placed on the EU market are within the scope of Regulation (EU) 2023/1542 (sustainability, due diligence, labelling, removability). Confirm applicable obligations against the specific OEM shipment.
