Use-case: mall-hybrid-50kW — one Sungrow SG50CX three-phase hybrid inverter paired with a Pylontech / CATL 60 kWh-class LFP battery rack and ≈ 60 kWp PV balance-of-system, used for retail-mall load-shaving and peak demand management in Argentina. Equipment: Sungrow SG50CX + Pylontech PowerCube-H1 / CATL 48100R-class LFP rack. Location: Argentina. Horizon: 25 years. Discount rate: 8.00 %. Evidence date: 2026-09-21. Limitation: this is a single-site, single-inverter block; multi-block mall sites need a separate quote.
Verdict (scenario model output, 2026-09-21): NPV = USD -76,872. IRR = -4.24 %. Simple payback = not reached in 25 years. Discounted payback = not reached in 25 years. LCOE = USD 0.1898 / kWh. At the modelled tariff, degradation and load-shape assumptions, this 50 kW hybrid block does NOT recover its all-in landed CapEx on a discounted basis within the asset horizon. It is a screening pass only if the buyer has a non-financial driver (resilience, demand-charge management, ESG reporting).
| Question | Result | Reason |
|---|---|---|
| Should this 50 kW hybrid block be procured under the modelled tariff & load? | NO (financial) | NPV -76,872 USD at 8 % over 25 yr; payback never reached. |
| Is the LCOE competitive vs. Argentine grid tariffs in 2026? | NO | USD 0.1898 / kWh LCOE is above current commercial AR tariff band referenced in CAMMESA spot data. |
| Should the buyer still RFQ for tariff, demand-charge or resilience reasons? | YES (non-financial) | Demand-charge reduction and outage ride-through may justify deployment even when NPV is negative. |
| Are all headline numbers on this page computed? | YES | NPV, IRR, payback, LCOE and the year-by-year cash flow are outputs of the computed Tradvolt TCO model. |

Year-0 cost of USD 100,000 represents all-in landed CapEx (inverter + LFP rack + PV BoS + international freight + insurance + Argentine import duties and VAT + inland haulage + installation & commissioning) used by the scenario model. Year-on-year cost escalation of ≈ 2 % from year 2 onward reflects O&M + escalation on spares & monitoring. Benefits rise each year from tariff escalation; energy declines from PV module degradation (see §3).

All per-line numeric rates (duties, VAT, internal taxes, individual CapEx / OpEx lines) are not asserted on this page and are resolved through the ARCA Nomenclador and the OEM quotation loop.
NPV = USD -76,872. IRR = -4.24 %. Simple payback = not reached in 25 years. Discounted payback = not reached in 25 years. LCOE = USD 0.1898 / kWh. These are outputs of the computed Tradvolt TCO model run dated 2026-09-21.
Sungrow SG50CX (three-phase string inverter used as the hybrid AC-coupled reference in this scenario), Pylontech PowerCube-H1 (high-voltage modular LFP rack, scalable to ≥ 60 kWh per cabinet) or an equivalent CATL 48100R-class LFP rack. All three are real, publicly marketed products with public OEM product pages (see §7).
The Argentine customs code (NCM, aligned with Mercosur) for static converters / power inverters normally sits under heading 8504. The exact 8-digit NCM subline must be confirmed on the ARCA Nomenclador portal at the time of import.
Common references are IEC 62109-1/-2 (power-converter safety), IEC 61727 / IEC 62116 (grid interface / anti-islanding) and IEC 62619 (industrial LFP cells). Transport of the LFP rack must satisfy UN 38.3. Local Argentine regulatory compliance (CAMMESA grid code, Secretaría de Energía Res. 314/2018) must be confirmed for each project.
No. The headline figures on this page (NPV, IRR, payback, LCOE, year-by-year cash flow) are SCENARIO OUTPUTS outputs of the computed Tradvolt TCO model. The underlying input assumptions (tariffs, escalation, degradation, DC/AC ratio, residual value, replacement policy) are explicit bounded model assumptions and must be re-stated in any RFQ response. The page is not a quotation, not an offer to sell, and not a contract.
Common arrangements include EXW, FOB, CIF and DAP (Argentine site). DDP is only usable after non-automatic licence review. The choice determines who pays freight, insurance and inland haulage; it is agreed in the RFQ response.
Yes — subject to scope review. We typically pair the OEM-equipment supply (Sungrow SG50CX + Pylontech PowerCube-H1 + PV) with a local Argentinian EPC partner for civil, mechanical and electrical installation, plus CAMMESA / Secretaría de Energía interconnection paperwork. Ask for the EPC scope in the RFQ.
