Pylontech US5000 4-module LFP rack (≈ 14.4 kWh usable) bundled with Deye SUN-5K-SG04LP3-EU 5 kW hybrid inverter, shipped CN → Port of Dakar → Senegal farm site. TCO and landed-cost framework, not a sales quote.
Smallholder farms, dairy and cold-chain cooperatives, irrigation pumping stations and rural agri-processing workshops across Senegal (Saint-Louis, Kaolack, Fatick, Tambacounda, Ziguinchor) typically pair a PV array + the Pylontech US5000 rack + a Deye SUN-5K-SG04LP3-EU hybrid inverter to displace diesel genset runtime, run refrigeration overnight and stabilise irrigation pumps. A 4-module US5000 rack is the smallest building block that covers one evening of small-farm load (lighting + fridge + irrigation-pump cycling).

HS code discipline. Heading 8507 (electric accumulators), lithium-ion sub-position 8507.60. The Pylontech US5000 is a 48 V LFP rack and is correctly classified under 8507.60; the Deye SUN-5K-SG04LP3-EU inverter is classified separately under 8504 (static converters), and PV modules under 8541 (photovoltaic cells). A bundled shipment should be declared line-by-line per Senegal valuation rules. Inverter/PV parts may attract a different CET band — confirm with broker.

Payback is most sensitive to diesel price and annual kWh displaced (farm load profile and irradiation year-on-year). Battery degradation at 2.00% per year is consistent with the Pylontech US5000 cycle-life claim of 6,000 cycles at 90% DoD; the model does not credit any residual asset value at year 20.

Heading 8507 (electric accumulators), lithium-ion sub-position 8507.60. Senegal applies a 20% CET duty under the ECOWAS Common External Tariff on this line (band 4 of the CET 2015 schedule). The precise Senegal national 10-digit line and any chapter-note exception must be confirmed on the Senegal Douanes tariff portal before quotation.
Senegal applies the ECOWAS CET 20% duty (band 4) on HS 8507.60, the UEMOA statistical levy (PCS) 1% on CIF, and TVA 18% on (CIF + duty + levies), per the Senegal Douanes portal and the UEMOA acts. Verify each line on douanes.sn before a binding quote is issued.
