Commercial & Industrial BESS · Air-Cooled · Outdoor DC Cabinet

112 or 225 kWh outdoor DC cabinet. Hybrid inverter, your choice.

Q: What does "DC cabinet" mean — where is the inverter?

Both 112 kWh-DC and 225 kWh-DC are battery-only enclosures — 112 kWh at 358.4 V, and 225 kWh at 716.8 V respectively. Neither includes an inverter. The HLY-Inverter-Hybrid mounts externally on the side bracket and handles AC conversion, MPPT solar input, and grid connection. Inverter size is selected per load profile at the time of order: 30–125 kW for the 112 kWh model; 100–125 kW for the 225 kWh model.

Q: What is the actual cycle life, and under what conditions?

≥8,000 full cycles at 80% depth of discharge, 0.5C charge and discharge rate, 25 °C cell temperature, to 70% end-of-life capacity. Those are the test conditions. Field performance varies with actual operating temperature, daily DoD, and discharge rate — Henley Power provides site-specific cycle projection on request for project finance cases.

Q: What does the warranty cover and for how long?

Five years standard, extendable to ten with a paid service agreement. Insurance-backed warranty option available for project-finance lender packages. The warranty covers cell capacity retention, BMS faults, enclosure integrity, and thermal management system performance. It doesn’t cover damage from incorrect installation, grid events outside the specified voltage range, or operating conditions outside the rated −20 °C to +50 °C window.

Q: Where is service provided in Europe and globally?

Nine-region service network: EU, Eastern Europe, Central Asia, Southeast Asia, West Africa, North Africa, with East Africa, Southern Africa, and LATAM in 2026 expansion. European projects are serviced from Romania — spare parts stocked in-region, no factory-direct lead times for field response. Field response target is defined in the active service agreement.

Q: What installations does the 112 kWh platform have in the field today?

The 112 kWh platform is in active deployment across C&I and telecom applications. First European delivery is a 10 MWh project in Moldova in Q2 2026 with a regional EPC partner — the front tranche of a 150 MWh pipeline. Factory reference installations in China are available on request under NDA.

Q: What certifications does it carry for project finance?

IEC 62619:2022, CE marking, UN 38.3, EU Reg 2023/1542. Manufacturing under ISO 9001, ISO 14001, ISO 45001. Test reports available under NDA on request. Full bankability package — cell qualification, BMS validation, thermal characterisation — provided for DFI-financed and institutionally backed tenders.

Q: What communication protocols does it support?

RS485, CAN, Ethernet, Modbus TCP, Modbus RTU, 4G, Wi-Fi. The BMS communicates with the paired HLY-Inverter-Hybrid over CAN as primary and RS485 as backup. The cloud EMS uses Modbus TCP over Ethernet or 4G. No proprietary protocol lock-in — if your SCADA speaks Modbus, it talks to this system.

Q: What is the lead time and minimum order?

35 days ex-works from Dezhou, Shandong. Minimum order is one unit. Delivery CFR to European ports. The HLY-Inverter-Hybrid ships separately and isn’t included in the battery cabinet price — request a bundled quote if you need both. Transit to Romania is typically 28–32 days on a direct vessel.

Q: Does the cabinet actually run at −20 °C in real Eastern European winters?

Yes — the rated operating window is −20 °C to +50 °C ambient, with the door-mounted HVAC unit holding internal cell temperature in the 15–30 °C optimum band. Active fan management and integrated cell heating handle the cold side; the cabinet is IP54 outdoor-rated against driven snow and wind-blown dust. Below −15 °C ambient, the BMS reduces charge current automatically to protect cell chemistry. We don’t recommend continuous operation below the −20 °C rating; for sites colder than that, request the cold-climate variant with enhanced heating.

Q: Can two cabinets parallel directly, or do you need an external DC busbar?

Up to ten units of the same model parallel on a shared external DC busbar — that’s how you reach 1.12 MWh (112 kWh-DC) or 2.25 MWh (225 kWh-DC). The busbar is an external switchgear panel, sized per project; it isn’t integrated into the cabinet because tying high-current DC inside a sealed enclosure creates fault-current paths you can’t isolate. Cabinets must be the same model (don’t mix 358 V and 716 V on one bus). The master BCU coordinates pack-level SOC balancing across the parallel string; the cloud EMS dispatches the array as a single resource to the inverter. Battery Safety

WHY THIS PLATFORM

Four reasons engineers specify this platform.

1P16S × 7 packs · 358.4 V · 314 Ah

Battery architecture that doesn't fight your inverter

Seven LFP packs in series deliver 358.4 V DC — squarely inside the MPPT input window of all HLY-Inverter-Hybrid models without a DC/DC conversion stage. No voltage mismatch. No efficiency penalty. Cobalt-free LiFePO₄ chemistry, IEC 62619 certified, 20-year design life at field conditions.

IP54 outdoor · HVAC + active fans · −20°C to +50°C

Air cooling that holds temperature without liquid

The cabinet runs a door-mounted HVAC unit backed by active fan management. It keeps cells within operating range across −20 °C to +50 °C ambient — no glycol loop, no pump maintenance, no leak risk. Air-cooled is the right call for C&I sites where a liquid-cooling maintenance contract isn’t realistic.

DC-parallel · up to 10 units · 1.12 or 2.25 MWh

Stack to project scale without rearchitecting

Connect up to ten 112 kWh-DC or 225 kWh-DC units DC-parallel on a shared busbar. Each 112 kWh unit adds 112 kWh; each 225 kWh unit adds 225 kWh. The BMS handles balancing across packs. One inverter can serve multiple cabinets, or add inverters as capacity grows — whichever fits the site power budget.

Aerosol · CO detection · active exhaust · thermal sensor

Four-layer fire protection in an outdoor cabinet

Aerosol suppression activates on thermal runaway detection. CO gas monitoring runs continuously. Active exhaust ventilation prevents gas accumulation. Cell-level temperature sensors feed the BMS before anything escalates to suppression. IP54 enclosure keeps water and particulate out of the control electronics.

TECHNICAL SPECIFICATIONS

Two models. One platform.

Both models share identical cabinet footprint, BMS architecture, cooling method, fire protection, and communication stack. What differs: pack count, DC voltage, usable capacity, and compatible inverter range. Test conditions per IEC 62619. Inverter specifications in the HLY-Inverter-Hybrid datasheet.

APPLICATION SCENARIOS

Where this cabinet deploys.

Demand charge management

Charge during off-peak windows, discharge at the daily demand peak. A 112 kWh / 50 kW system reduces demand charges 15–30% on sites drawing 150–500 kW peak — typical for light manufacturing, cold storage, and logistics. This doesn’t replace a properly sized transformer; it defers the upgrade for 5–10 years.

Solar self-consumption boost

The HLY-Inverter-Hybrid’s integrated MPPT captures surplus PV generation and routes it directly to battery charge. Self-consumption ratios above 90% are achievable on properly sized PV-to-storage ratios — typically 1:1 to 2:1 kWp per kWh storage. Works without a separate solar inverter, cutting BOS cost on new-build sites.

Critical load backup

At 0.5C continuous discharge, 112 kWh gives two hours of autonomy at 50 kW load. The hybrid inverter switches from grid to island mode on outage detection — transition time depends on inverter model, typically under 20 ms. Not a replacement for a UPS on sub-100 ms critical loads; a complement to one.

EV charging buffer

A 112 kWh buffer absorbs EV charging demand spikes that would otherwise trigger demand-charge events or require grid reinforcement. Charge the buffer overnight at flat-rate tariff; dispatch during fast-charge events at the site. Doesn’t replace a dedicated EV charger management system — it sits behind it on the AC bus.

Time-of-use arbitrage

In markets where time-of-use tariff spreads exceed €40–60/MWh, a 112 kWh system running two full cycles per day can recover €3,000–5,000 per year in avoided grid costs. The economics improve as tariff volatility increases — which it is, across most European markets in 2026.

Telecom & remote sites

IP54 cabinet, rated to −20 °C — the 112 kWh-DC deploys at telecom base stations, remote monitoring installations, and off-grid infrastructure without a climate-controlled enclosure. Pairs with a small HLY-Inverter-Hybrid and a PV array for autonomous operation. Lead time is 35 days from Dezhou, Shandong.

What is the actual cycle life, and under what conditions?

≥8,000 full cycles at 80% depth of discharge, 0.5C charge and discharge rate, 25 °C cell temperature, to 70% end-of-life capacity. Those are the test conditions. Field performance varies with actual operating temperature, daily DoD, and discharge rate — Henley Power provides site-specific cycle projection on request for project finance cases.

What does the warranty cover and for how long?

Five years standard, extendable to ten with a paid service agreement. Insurance-backed warranty option available for project-finance lender packages. The warranty covers cell capacity retention, BMS faults, enclosure integrity, and thermal management system performance. It doesn’t cover damage from incorrect installation, grid events outside the specified voltage range, or operating conditions outside the rated −20 °C to +50 °C window.
