0. Verdict & Decision Table

Scenario verdict (Sungrow SH15T 15 kW hybrid inverter, CN → Denmark, 25-yr horizon, 8 % discount rate, CapEx €1,790 ex-VAT B2B, Year-1 benefit €2,214, Year-1 OpEx €582):

Decision metric	Value	Read
NPV	€16,523.04	Strongly positive at 8 % discount rate over 25 years
Simple payback	1.10 yr	CapEx recovered within ~13 months of operation
Discounted payback	1.20 yr	CapEx recovered within ~14 months on a discounted basis
LCOE	€0.0662 / kWh	Discounted cost per kWh of delivered energy over 25 years
IRR	0.9180	Project internal rate of return on undiscounted cash flows
PV of total costs	€9,166.29	Discounted cost base over 25 years
PV of total benefits	€25,689.33	Discounted benefit base over 25 years
Total undiscounted cost	€20,431.63	CapEx + 25 yr OpEx (no discounting)
Total undiscounted benefit	€62,472.36	25 yr gross benefits (no discounting)

Go-decision benchmark: NPV > 0, discounted payback < 3 yr, LCOE within the buyer's avoided-tariff band. The modelled scenario meets all three. The remaining risk is the EU TARIC duty line (currently PENDING on the live lookup) and the site-specific self-consumption ratio, both of which Tradvolt confirms at RFQ time.

4. CapEx — Landed Cost Framework

The CapEx lines below reconcile to the Year-0 cost of €1,790.00 used by the scenario model. The EU TARIC duty line is marked PENDING and is performed live at RFQ time on the official EU TARIC consultation.

Line item	Unit	Range	Midpoint
OEM Ex-Works (Sungrow SH15T)	EUR / unit	1,100 – 1,450	1,275
Inner carton + export pallet (ISPM 15)	EUR / unit	25 – 45	35
Pre-shipment inspection (third-party)	EUR / shipment	120 – 220	170
Ocean freight CN→DK port (FCL/LCL)	EUR / CBM or / unit	80 – 180	130
Cargo insurance (0.3 % of CIF)	EUR / unit	4 – 6	5
EU import duty (TARIC, DK national measures, HS 8504.40)	EUR / unit	PENDING — live TARIC lookup	PENDING
Customs broker fee (DK entry)	EUR / shipment	80 – 150	110
Danish VAT (25 %, recoverable for B2B with valid VAT ID)	EUR / unit	0 (B2B input VAT recoverable)	0
Last-mile delivery (DK port → site)	EUR / unit	45 – 90	65
Indicative landed CapEx (B2B, ex-VAT)	EUR / unit	1,500 – 2,200	1,790

HS national line | Programme | As-of: 2026-09-21 | Status: PENDING

Official portal: EU TARIC consultation (European Commission, DG TAXUD).
Code placeholder: PENDING — candidate lines for static converters fall under HS 8504.40 (see the USITC HTS search and the EU TARIC consultation); the exact national subheading, EU measure code, and applicable rate must be confirmed live on TARIC at quotation.
Duty rate: PENDING — TARIC returns the third-country duty and any erga omnes / preferential rate; any anti-dumping or surveillance measure, if applicable, must also be checked.
VAT: Danish VAT standard rate 25 % applies on import; for B2B buyers with a valid Danish VAT ID, import VAT is recoverable via the regular VAT return.

5. OpEx — Annual Operating Expenditure

OpEx is built from the line items below to give the Year-1 total of €582 used by the scenario model. Year-over-year escalation is 2 %/yr.

Cost driver	Basis	Year-1 cost (EUR)
Preventive maintenance (1 visit / yr)	€180	180
Firmware / monitoring subscription	€65 / yr	65
Spare parts allocation (fans, contactors, DC fuses)	~1.5 % of CapEx	27
Remote O&M labour (DK on-call)	2 h @ €95/h	190
Annual functional & safety test (lab BoS)	€120 / yr	120
Year-1 OpEx total	—	582

6. Benefit Stream & Energy Throughput

Benefits are energy-cost displacements valued at the site's avoided electricity tariff. The modelled benefit escalates at 1.5 %/yr against a PV degradation of 0.5 %/yr, starting from a Year-1 throughput of 13,500 kWh.

Year	Energy (kWh)	Benefit (EUR)
1	13,500.00	2,214.00
5	13,232.02	2,303.21
10	12,904.51	2,419.80
15	12,585.11	2,542.29
20	12,273.61	2,670.98
25	11,969.82	2,806.19

7. Model Assumptions (explicit, bounded)

Inputs the original draft did not state. Presented as bounded model assumptions, not sourced facts:

Residual value (asset.pv.residual_value): €0 at end of Year 25 (conservative; asset fully depreciated for TCO purposes). Bound: 0 ≤ residual ≤ 10 % of CapEx.
Residual year (asset.pv.residual_value.year): 25 (aligned with horizon).
PV degradation (asset.pv.degradation_pct_per_year): 0.5 %/yr linear, applied to Year-1 throughput of 13,500 kWh. Bound: 0.3 %–0.7 %/yr.
Tariff escalation (asset.pv.tariff_escalation_pct): 1.5 %/yr nominal. Bound: 0 %–3 %/yr.
Export tariff (asset.pv.export_tariff_per_kwh): €0.00/kWh (lab/BoS use case — site is net-self-consuming; export treated as non-revenue).

All other inputs (CapEx €1,790, OpEx €582 Year-1, energy 13,500 kWh Year-1, 8 % discount rate, 25-yr horizon) are reconciled to the computed cash-flow table above.

10. Frequently Asked Questions

What is the typical landed cost for a 15 kW hybrid inverter imported from China to Denmark?

The modelled scenario uses an indicative landed CapEx of €1,790 (ex-VAT, B2B), reconciled to the Year-0 cash flow. The EU TARIC duty line is marked PENDING and is resolved live at RFQ time. Total PV of costs over 25 years is €9,166.29.

Which certifications are required for a 15 kW hybrid inverter installed in Denmark?

CE marking under LVD (Directive 2014/35/EU), EMC (Directive 2014/30/EU) and RED (Directive 2014/53/EU) where a comms module is present, plus grid-tie compliance with EN 50549-1:2019 and EN 50549-10:2019 confirmed by the Danish DSO. Inverter safety is verified against IEC 62109-1:2010 and IEC 62109-2:2011. Battery pairing is evaluated against IEC 62619:2022 (stationary LFP) and UN 38.3 (transport).

What is the typical payback period for a 15 kW hybrid inverter in a lab or BoS application?

In the modelled scenario, simple payback is 1.10 yr and discounted payback is 1.20 yr at an 8 % discount rate. NPV is €16,523.04 and LCOE is €0.0662/kWh. Actual payback depends on the OEM price at order, the site's tariff, self-consumption ratio, and the resolved EU TARIC duty line.

Does a 15 kW hybrid inverter qualify for LFP / energy-storage integration?

Yes — the Sungrow SH15T pairs with Sungrow SBH100-400 (5 kWh per module, 10–40 kWh per unit) and SBR064-256 (3.2 kWh per module, 6.4–25.6 kWh per unit). Battery chemistry, BMS, and voltage window must be confirmed against the OEM compatibility list before procurement. LFP transport is governed by the UN Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.7, §38.3, and stationary LFP systems are evaluated against IEC 62619:2022.

What HS code applies to hybrid inverters imported into Denmark?

Candidate HS lines for static converters fall under 8504.40. The exact TARIC measure and duty rate must be looked up live on the EU TARIC consultation at quotation. Cross-reference entries can be checked against the USITC Harmonized Tariff Schedule. Tradvolt performs the lookup as part of the formal RFQ response.

How long does a Tradvolt RFQ take to reply?

All qualified RFQs receive a response within 48 hours during EU business days, including indicative Ex-Works pricing, lead time, sea-freight options, and the resolved EU TARIC duty line.
