Import Pylontech US5000 (19.2 kWh nominal / 16 kWh usable) from China to Ukraine — Villa Backup TCO

Verdict (illustrative, 25-year horizon, 8.00 % discount rate, USD): For a four-module Pylontech US5000 stack (19.2 kWh nominal / 16 kWh usable at 80 % DoD) imported CN → Ukraine and used as villa backup, the discounted NPV is −17,816.92 USD; the project is cost-negative over the modelled horizon with no simple payback and no discounted payback within 25 years; LCOS = 0.1899 USD/kWh. Equipment: Pylontech US5000 (4× stack). Location: Ukraine (villa backup). Horizon: 25 years. Evidence date: 2026-09-21. Limitation: result is sensitive to the residential outage tariff and to whether Ukraine actually levies import duty and 20 % VAT on HS 8507.60 (see bounded assumptions).

Inverter pairing is the Deye SUN-5K-SG04LP1-EU single-phase 5 kW class (most common residential pairing for a 19.2 kWh Pylontech US5000 stack). Tariff 0.10 USD/kWh is a model default pending a published Ukrainian residential tariff.

Payback & Sensitivity — ILLUSTRATIVE — NOT A QUOTE

Method. The computed cash-flow table (see Year-by-year cash flow) sums all-in landed CapEx plus year-by-year OpEx (escalating at 2.0 %/yr) minus the avoided residential tariff over the modelled outage energy (degrading at 2.0 %/yr). The result is a negative NPV of −17,816.92 USD over 25 years at 8.00 % discount rate; no payback is reached inside the horizon.

Sensitivity table (simple payback, years) — recomputed

Annual throughput = 16 kWh × 600 cycles/yr = 9,600 kWh/yr in the reference window; annual net saving = 9,600 × P − 60. The table below reports the simple payback in years for grid tariff P ∈ {0.07, 0.10, 0.13} USD/kWh and CapEx ∈ {3,200, 3,556, 4,000, 4,500} USD. Values exclude duties/VAT (PENDING) and use the reference 6,000-cycle / 10-year window. Recomputed by the scenario TCO model; the prior 5.6-yr cell is corrected.

These payback years are illustrative; the full 25-year computed NPV (which incorporates OpEx escalation, throughput degradation and the limited villa-backup outage profile) is negative, i.e. no payback within the horizon.

FAQ

1. What HS code is used for LFP batteries imported into Ukraine?

The reference classification is HS 8507.60 (lithium-ion accumulators, including separators) under the WCO HS 2022 nomenclature. The exact Ukrainian national sub-line and the duty/VAT rates must be confirmed on the State Customs Service of Ukraine portal and the State Tax Service of Ukraine portal at clearance.

2. Which OEM product is modelled?

A four-module stack of Pylontech US5000 (manufacturer product page) — 4.8 kWh nominal per module, 3.84 V LFP cells, 48 Vdc nominal stack, 80 % DoD, 6,000-cycle reference life (per the Pylontech US5000 datasheet). Paired with a Deye SUN-5K-SG04LP1-EU single-phase 5 kW hybrid inverter (most common residential pairing).

3. What is the assumed cycle life used in the TCO model?

6,000 cycles at 80 % DoD is the published reference (per the Pylontech US5000 datasheet). Year-by-year energy throughput is scaled by the bounded 2.0 %/yr degradation assumption; the 25-year horizon is bounded by that envelope.

4. Does the TCO include installation and balance-of-system?

Yes. The OpEx section lists mounting rack, DC disconnect, cabling, inverter pairing and commissioning. Costs are illustrative engineering references, not a Tradvolt quote.

5. Can Tradvolt ship DDP to a Ukrainian address?

Yes, on request. Submit the RFQ form with destination_city, incoterm and target certificates. Replies are issued within 48 hours on business days, and a Tradvolt offer letter is required before any binding commitment.

6. Is this page a Tradvolt commercial quote?

No. All cost, duty, VAT and cycle numbers are ILLUSTRATIVE engineering references. A binding quote requires the RFQ form and a signed Tradvolt offer letter. Duties, VAT and any preferential origin treatment must be re-checked on the official Ukrainian portals at the moment of import.
