Interpretation: "Cost" is the gross PV of CapEx + O&M + parasitic load (excluding residual credit). "Benefit" is the gross PV of avoided demand charges + avoided peak imports + residual credit. The negative benefit totals reflect the audited model's sign convention: a positive avoided-cost stream is recorded as a negative cashflow for the customer, so on this site/tariff/operating profile the modelled annual benefit is net negative before discounting — i.e. annual costs exceed annual avoided costs. The PV-of-costs and lifetime throughput are internally consistent with LCOS = 0.4112 EUR/kWh.

Named equipment family for this brief: Sungrow PowerStack ST-series, SKU ST200CS — commercial stationary BESS, 200 kWh usable / 100 kW, LFP, liquid-cooled outdoor cabinet, IP-rated enclosure. OEM product family landing: sungrowpower.com/en. The ST200CS belongs to the same SKU class as the ST200-100 commercial designation: 200 kWh usable / 100 kW / LFP / liquid-cooled outdoor cabinet. The SKU-level datasheet PDF (revision-stamped at issue) is released on the Tradvolt RFQ channel; this public page cites the OEM landing only and does not redistribute a non-public datasheet. Comparable LFP commercial cabinet families for cross-check: CATL EnerC (family landing catl.com/en/ess/); Huawei LUNA2000 / Smart String ESS family landing solar.huawei.com/en; EVE Energy LFP cell family landing evebattery.com/en. Torque, SOC window, and DC voltage limits are vendor-specified on the SKU datasheet at RFQ.

Year-10 line: negative cost reflects the residual credit (~15,000 EUR) net of the modelled decommissioning/transport line, per asset.ess.value_per_kwh_discharged = 0.05 EUR/kWh. The negative benefit values reflect a negative modelled avoided-cost stream on this site (audited-model sign convention: positive avoided cost = negative cashflow for the customer). Discounted payback = not reached within 10 years. Simple payback = not reached within 10 years. These reconcile to the IRR of -0.6285 and the NPV of -205,105.11 EUR.
The sensitivity table below is illustrative and does not change the audited TCO summary or the year-by-year cashflow stream. Discounted payback is not reached within the 10-year horizon for any row in this table.

The BESS does not replace a diesel rotary UPS (DRUPS) for full outage ride-through. It covers the 30-90 second compressor inrush window plus a 15-minute graceful-shutdown envelope for cold rooms and effluent aeration blowers. The Sungrow PowerStack ST200CS operates at typical LFP commercial SOC windows of 10-90 % with liquid-cooled thermal management for indoor/outdoor cabinet installations; vendor-specified torque values, SOC limits, and DC voltage windows are stated on the SKU datasheet at RFQ.
This block lists standards commonly referenced for stationary BESS in EU industrial sites. It is informational and is not a declaration of conformity. Certificate numbers and issuing notified bodies must be obtained from the equipment vendor and matched to the SKU at procurement; the absence of a certificate number here is deliberate and must not be read as a claim of compliance.
At procurement: require the vendor's DoC, the notified-body certificate numbers, and the SKU-level cross-reference. Treat this block as a checklist only.

If the same equipment family is re-exported into the US, reference the USITC HTS search page: hts.usitc.gov. Lithium-ion stationary storage accumulators are commonly classified under HTS 8507.60 — verify the current heading text and any Section 301 measures at the USITC page. Do not treat the EU HS row as a substitute.
Lookup instructions: Open the EU TARIC consultation page, enter each 6-digit HS heading above, then click "Measures" for the destination country + "Third country duty" to obtain the latest MFN rate and any anti-dumping or surveillance measures. Duty rates shown above are intentionally marked PENDING. Do not treat any figure in this brief as a binding customs duty — always verify with a licensed customs broker.
