Worked example — assumed inputs (illustrative only):
| Input | Illustrative value | Where this will come from in a real quote |
|---|---|---|
| Unit landed cost (all-in DAP CZ) | €3,800 / unit (illustrative) | RFQ + duty lookup |
| Inverter + installation | €1,400 (illustrative) | Installer / inverter OEM |
| Total CapEx per site | €5,200 (illustrative) | Sum of above |
| Annual PV self-consumption shifted to battery | 2,200 kWh / year (illustrative) | PV yield × self-consumption ratio |
| Imported electricity price (CZ household) | €0.28 / kWh (illustrative — confirm on official CZ energy regulator portal) | CZ energy regulator / retail tariff |
| Annual savings (energy arbitrage only) | 2,200 × 0.28 ≈ €616 / year | |
| Simple payback (energy arbitrage only) | 5,200 ÷ 616 ≈ 8.4 years (illustrative) |
Sensitivity table (illustrative):
| Electricity price (€/kWh) | Annual savings | Simple payback vs. €5,200 CapEx |
|---|---|---|
| 0.20 | €440 | ~11.8 years |
| 0.25 | €550 | ~9.5 years |
| 0.30 | €660 | ~7.9 years |
| 0.35 | €770 | ~6.8 years |
| 0.40 | €880 | ~5.9 years |
If backup value, feed-in tariff, or demand-charge avoidance is counted, payback shortens. Do not combine them in this table without citing each on its own portal.

No duty, tariff, or VAT rate is hardcoded on this page. All rates are PENDING — lookup on the official EU TARIC database and the Czech customs / tax administration portals at the moment of each specific shipment. If you need a binding ruling, apply via the official EU TARIC consultation mechanism and the Czech customs authority.
Submit the fields below. Tradvolt replies with a supplier-quoted FOB, freight estimate, and a duty-stack template referencing the official EU TARIC and Czech customs portals.
Download the OEM datasheet for the SKU you intend to import. The datasheet is the only document to trust for cycle life, dimensions, terminal type, and inverter pairing.

Lithium-ion storage batteries commonly fall under HS heading 8507.60 in the EU. The exact 8-digit TARIC code, national line treatment, and any binding ruling must be confirmed on the official EU TARIC portal and the Czech customs information portal before quoting. Treat all duty/VAT rates on this page as PENDING — lookup.
Commonly referenced standards include IEC 62619 (secondary lithium cells for industrial / light EV / stationary applications), IEC 63056 (secondary lithium batteries for energy storage), UN 38.3 (transport), and CE marking under the applicable EU directives. The final certification list must be confirmed with the OEM and your notified body.
No. All CapEx, OpEx, and payback figures are labelled ILLUSTRATIVE — NOT A QUOTE. They depend on your unit FOB price, freight lane, Incoterm, duty treatment, electricity tariff, and self-consumption ratio, all of which must be re-validated per RFQ.
Submit the RFQ form above with product_sku, qty, Incoterm, target_cert, and destination_country = Czechia. Tradvolt replies within 48 hours with a supplier-quoted FOB, freight estimate, and a duty-stack template referencing the official EU TARIC and Czech customs portals.
OEM datasheets for residential LFP products in this capacity range commonly quote values around 6,000 cycles at 80% depth-of-discharge, but the exact figure must be read from the specific datasheet you procure. Do not assume a number without the document.
Yes — placing LFP batteries on the Czech market generally triggers producer-responsibility (battery / WEEE) obligations. Confirm the exact registration pathway and current thresholds on the official Czech environment ministry portal before placing the first shipment on the market.
All figures, rates, and standards on this page must be re-verified at the moment of each specific transaction against the named official portals above. No specific OEM datasheet, test certificate number, or binding tariff ruling is asserted on this page.
