Commercial & Industrial BESS · Liquid-Cooled · Outdoor Cabinet

200 kW / 418 kWh in one outdoor cabinet.

Q: What's the difference between the 112, 261, and 418?

Same family, three sizes, same BMS, EMS, and warranty. The 418 and 261 are liquid-cooled; the 112 is air-cooled and suited to smaller sites or milder climates. Choose by site capacity.

Q: What is the cycle life and how is it rated?

10,000 cycles at 80% DoD, 0.5C, 25°C, EOL at ≥70% SOH. One cycle per day = 27-year budget. Design life 25 years. Third-party test reports under NDA on request.

Q: Can I stack the 418 to reach 1 MWh or higher?

Yes — up to 40 cabinets in parallel, 16.7 MWh / 8 MW on one BMS and one EMS. AC interconnection at 690 V three-phase; MV grids need a project step-up transformer.

Q: Why 1,331 Vdc? What does this mean for my project?

Higher voltage, lower current at the same power. Smaller cables, smaller switchgear, lower I²R losses across project life. Most C&I cabinets in this size class run 614–900 Vdc — the gap shows up in BoP cost per MWh installed.

Q: What cells are inside the 418?

Tier-1 LFP cells from publicly listed manufacturers, multi-supplier homologated. Specific partner named in the supply contract per project — we don’t publish it here because cell supply relationships shift across a 25-year product life.

Q: What's the warranty and what does it cover?

5-year system warranty covering cells, BMS, integrated PCS, liquid cooling, and controls. 5-year battery extension pre-priced at order signing — no surprise renewals at year 5. EOL at 70% SOH. Warranty service handled regionally. Insurance-backed option available for DFI-financed and institutionally-backed tenders. Parent guarantee or escrow on request.

Q: What SCADA and EMS platforms are compatible?

Open protocols — no proprietary lock-in. Modbus TCP/RTU, CAN, RS485, IEC 60870-5-104, IEC 61850-7-420 DER profile (optional), DNP3. Project-specific edition confirmed at commissioning. Compatible with major European TSO grid codes including ENTSO-E. TSO qualification (50Hertz, TenneT, RTE, Energinet, Fingrid, National Grid ESO, Transelectrica, etc.) confirmed per project. OTA firmware updates via Cloud EMS.

Q: What's the lead time and minimum order?

35 days ex-works from contract signature and deposit. CFR European ports adds 30–35 days transit. No minimum order. First EU delivery: 10 MWh, Moldova, Q2 2026.

HLY-BESS-Commercial-Industrial-418kWh

The 418 kWh cabinet is Henley Power’s largest C&I outdoor BESS — 200 kW / 418 kWh at 1,331 Vdc, LFP chemistry across eight liquid-cooled modules. Rated at 10,000 cycles at 80% DoD to 70% SOH end-of-life. 25-year design life. Operating range −20°C to +55°C charge, −20°C to +50°C discharge. Stackable to 40 cabinets — 8 MW / 16.7 MWh on one BMS. Engineered and manufactured by Henley Power in Shandong, China; European projects serviced from Romania.

PRODUCT FEATURES

Four reasons engineers specify the 418.

Cell ΔT ≤ 2°C · liquid cooling at C&I scale

Intelligent Liquid Cooling

Closed-loop ethylene glycol holds cell ΔT under 2°C. Most C&I cabinets run air-cooled at 5–8°C spread. Tighter thermal uniformity is the biggest single lever on cycle life.

1,331 Vdc · lower current · less copper

High-Voltage DC Architecture

1,331 Vdc nominal — near the upper envelope of 1,500 V-rated equipment. Higher voltage means lower current, smaller cables, smaller switchgear, lower I²R losses. The savings land in BoP cost.

Triple fire protection · pack + cabinet + detection

Three-Layer Fire Suppression

Pack-level Novec, cabinet-level aerosol, CO and thermal detection on every module. UL 9540A tested. It’s more expensive than single-layer alternatives — engineers who read insurance terms understand why we made this standard, not optional.

Stackable to 16.7 MWh · 40 cabinets · one EMS

One BMS Architecture, One to Forty Cabinets

Single cabinet: 200 kW site anchor. Forty in parallel: 8 MW / 16.7 MWh on one BMS. Same architecture, same EMS, same warranty — cabinet count is the only variable.

TECHNICAL SAPECIFICATIONS

One cabinet. Three deployment modes.

Top of Henley Power’s C&I range, sharing BMS architecture, EMS, and warranty structure with the 261 and 112. Spec table reflects Mode A (All-in-One integrated PCS). All values per IEC 62933-2-1.

TOPOLOGY . DEPLOYMENT MODES

Three ways to deploy the 418.

Three power-conversion topologies. Battery, BMS, thermal, and EMS are identical across all three. Only the PCS strategy differs — choose by site architecture and target dispatch markets.

Mode A · All-in-One

Integrated PCS

On-board PCS at 200 kW (215 / 225 kW optional). Plug-and-play for single-cabinet C&I behind-the-meter: peak-shaving, demand-charge management. Direct AC interconnect at 690 V three-phase.

SKU · HLY-BESS-Commercial-Industrial-418kWh

Mode B · DC-only

+ Central PCS 630–2,500 kW

DC-only block, multiple cabinets sharing one central inverter. Fewer conversion stages, lower cost per MWh at array scale. Suited to FCR / aFRR / arbitrage and solar-plus-storage co-location.

SKU · HLY-BESS-Commercial-Industrial-418kWh-DC

Mode C · DC-only

+ Hybrid inverter 30–125 kW

DC-only block with hybrid inverter handling both PV MPPT and battery dispatch. Best fit for commercial rooftops, light industrial, and small islanded microgrids with on-site PV.

SYSTEM ARCHITECTURE

Built for 25 years of commercial operation.

LFP · 314 Ah · Tier-1 cells · multi-supplier homologated

Cell & Battery System

LiFePO₄, 3.2 V / 314 Ah prismatic cells, 1P416S in eight modules at 1,331 Vdc. Tier-1 cells from publicly listed manufacturers, multi-supplier homologated — no single-vendor dependency over a 25-year product life. Specific cell partner named in the supply contract, not in marketing copy.

Henley Power integrated PCS · 200 kW · ≤20 ms · 4-quadrant

Power Conversion System (PCS)

Integrated PCS at 200 kW (215 / 225 kW optional). DC range 1,040–1,498 V, AC output 690 V three-phase. Response ≤ 20 ms (inverter switching); full system activation under 500 ms — those aren’t the same number. 4-quadrant reactive power, LVRT/HVRT per grid code.

3-level · ±5 mV cell · SOC ±2% · active balancing

Battery Management System (BMS)

Three-level hierarchy: cell, module, system. A module trips without shutting the cabinet — SOC accuracy ±2%, continuous SOH tracking, active cell balancing. It’s the single biggest determinant of whether the warranty means anything over a 25-year life.

AI dispatch · OTA · Modbus TCP · IEC 61850-7-420 · DNP3

Cloud EMS & Communication

Cloud EMS, AI dispatch, OTA firmware. Open protocols: Modbus TCP/RTU, CAN, RS485, IEC 60870-5-104, IEC 61850-7-420 DER profile, DNP3. Project-specific edition confirmed at commissioning. Connects to whatever SCADA platform the customer already runs — not just the ones we’d prefer.

APPLICATIONS SCENARIOS

Where the 418 deploys.

Peak Shaving & Demand-Charge Reduction

Charge during low-tariff windows, discharge at peak demand. Cuts industrial demand charges 15–30% on properly sized sites. Not suited for whole-site islanding — that’s a multi-cabinet array application.

Solar Self-Consumption

Stores rooftop or ground-mount PV during the day, discharges into evening peak. Lifts commercial self-consumption toward 75%+ on well-matched sites. Doesn’t substitute for net-metering where export tariffs make that the better economics.

Frequency Regulation & Grid Services

≤ 20 ms PCS response qualifies for FCR-N, FCR-D, FFR, and aFRR across ENTSO-E areas. Stack 4–10 cabinets to reach minimum bid sizes — single-cabinet bids fall short on most European TSOs.

Critical-Load Backup

200 kW continuous discharge, 2-hour full cabinet duration. System activation under 500 ms — UPS-grade transition. Suited to control rooms, server rooms, and life-safety circuits.

EV Charging Hub Buffering

200 kW grid feed plus 418 kWh buffer supports 400+ kW peak charging without grid upgrade — useful for 4–8 DC fast chargers during simultaneous-charge events.

EPC Project Building Block

Stack to 16.7 MWh / 8 MW across 40 cabinets, 690 V three-phase AC interconnection with project step-up transformer for MV grids. One BOM, one warranty structure, one EMS across the array.
