9 · FAQ
- What HS code should I use to import a 15 kW hybrid inverter into Sweden?
- Static converters are classified in HS heading 8504. The likely subheading for hybrid PV inverters is 8504.40. Confirm the exact 8-digit TARIC measure for your SKU at the official EU TARIC consultation before declaring.
- Are the CapEx/OpEx figures on this page a quoted offer?
- No. All figures are ILLUSTRATIVE and NOT A QUOTE. Tradvolt prices are issued only against a written RFQ with product_sku, qty, incoterm, target_cert, destination_country and buyer details.
- Which certificates are normally expected for the Sungrow SH15T in Sweden?
- The Sungrow SH15T ships with an IEC 62109-1/-2 test certificate and an EN 61000-6 EMC report. The EVE LF280K rack is covered by a UN 38.3 cell-level test summary. Always request the numbered PDF from your account manager.
- What is the LFP-cycle reference used for OpEx calculation?
- The OpEx line uses the EVE LF280K datasheet cycle-life figure (6,000 cycles to 80 % capacity at 25 °C, 0.5 C, 80 % DoD, rev. EVE_LF280K_DS_EN_202306). Actual delivered cycles depend on DoD, C-rate and ambient temperature; confirm the exact number on the datasheet shipped with your SKU.
- Can I substitute FOB or DDP terms in the RFQ?
- Yes. Select EXW, FOB, CFR, CIF, DAP or DDP under incoterm in the RFQ form; Tradvolt will re-quote on the requested basis.
- How long does an RFQ reply take?
- Tradvolt replies to qualified RFQs within 48 hours during working days.
