AT A GLANCE
Henley Power’s modular battery energy storage system powers small offices, retail stores, EV charging hubs, supermarkets, and telecom sites across European C&I deployments. The 32.2 kWh LiFePO₄ module scales 3 to 78 units per cluster — 96 kWh to 2.5 MWh — covering everything from a 200 kW retail demand-charge cluster to a 2 MW industrial park microgrid. Air-cooled IP21 indoor enclosure delivers the lowest €/kWh in its commercial energy storage segment. Manufactured in Dezhou, Shandong. European projects serviced from Romania across a 9-region service network.

WHY SPECIFIERS CHOOSE MODULAR OVER MONBLOCK

Four reasons the modular rack wins on €/kWh.

Most commercial-industrial BESS ships as a fixed-size cabinet with an integrated PCS. That bundling carries 18 to 25% cost overhead that disappears when air-cooling and DC-only architecture take over.
NO CHILLER. NO GLYCOL LOOP. ~ 18-25% BOM SAVING

Air-Cooling Removes A Cost Block.

A liquid-cooled BESS carries a chiller, glycol pumps, cold-plate manifold, and the controls to balance flow across modules. That hardware is roughly 18 to 25% of the BoM. Air-cooling needs fans, intake filters, and exhaust paths. The cost gap is real and shows up at the invoice.
DC- ONLY. CUSTOMNER CHOOSE INVERTER. OPEN BMS PROTOCOL

The PCS Market Is Already Commoditised.

String PCS, hybrid inverters, and central PCS are sold by Sungrow, SMA, Sineng, Sofar, Goodwe, Hopewind, Deye, and Victron at competitive prices. Bundling a captive PCS into a sealed BESS forces a margin stack. Shipping DC-only lets the customer or EPC source the inverter where pricing already favours them.
3 TO 78 MODULES· 96 KWH TO 2.5 MWH· 32.2 KWH STEPS

Pay For The Capacity You Need.

A monoblock cabinet sized for 261 kWh is still 261 kWh when the project requires 180 kWh. The modular rack scales in 32.2 kWh increments. A site that needs 480 kWh buys 15 modules. A site that grows to 800 kWh adds 10 more. Capacity matches load — no stranded capex.
35-DAY LEAD TIME ]· PALLET DELIVERY. INDOOR INSTALL

Faster To Delivery, Simpler To Install.

Modules ship on standard pallets, not in a 20-foot container. Indoor IP21 deployment removes weatherisation, foundation pad, and structural fees. A small electrical room, a standard rack, three to twelve modules per rack. No crane, no civil work, no outdoor commissioning window.
TECHNICAL SPECIFICATIONS

THREE DEPLOYMENT TOPOLOGIES

Pair the cluster with the inverter the project needs.

The cluster ships DC-only with RS485 Modbus RTU and CAN 2.0B. Inverter selection sits with the customer or EPC. All three topologies below have been deployed commercially.
Mode A — String PCS

Cluster + string PCS

Cluster pairs with one or more string PCS rated for 696 to 922 Vdc input. Standard architecture for grid-tied commercial peak-shaving and demand-charge applications. Sungrow SC, Sineng EP, Hopewind PowerWind, and equivalents qualify if voltage range matches.
SKU: HLY-BESS-Commercial-Industrial-Modular-32kWh-DC
Typical sizing: 100–500 kW per PCS
Mode B — Hybrid inverter

Cluster + hybrid inverter

Cluster pairs with a hybrid inverter that combines PV input and battery DC bus on the same chassis. Standard architecture for sites combining rooftop or carport PV with storage, or for grid-forming island-mode operation. Deye, Goodwe, Sofar HYD, Victron MultiPlus, SMA Sunny Tripower-S typical pairings.
SKU: HLY-BESS-Commercial-Industrial-Modular-32kWh-DC + HLY-Inverter-Hybrid
Typical inverter: 30–125 kW per unit
Mode C — Central PCS

Multi-cluster + central PCS

Multiple clusters paralleled at the DC bus and connected to a central PCS rated 630 kW to 2.5 MW. Standard architecture for the upper end of the modular range — sites running 1.5 to 2.5 MWh where a single large inverter is more cost-effective. MV transformer interconnection typical.

WHERE THIS PLATFORM DEPLOYS

Six commercial buyer verticals deployed.

Each vertical sizing example below assumes typical European C&I load profiles. Final cluster sizing depends on metered load data, tariff structure, and backup requirements.

Small Offices & Retail Stores

Office buildings under 2,000 m² and retail stores draw 20-60 kW base load with afternoon peaks. A 3-module cluster (96 kWh, 768 V class) covers a typical retail demand-charge cycle on a 100 kW connection. PV self-consumption mode absorbs rooftop export during business hours. Indoor IP21 enclosure suits utility rooms and storage areas. Payback depends on the local demand charge tariff.

EV Charging Hubs

Highway and urban DC fast-charging hubs with three to six 150 kW chargers see instantaneous grid spikes that trigger demand penalties or require grid reinforcement. A 6 to 9 module cluster (193-290 kWh) buffers those spikes — battery discharges during charging events, recharges between sessions. For 350 kW HPC hubs, cluster sizing scales with simultaneous-charging load. DC-coupled deployment minimises conversion losses.

Supermarkets & Food Retail

Supermarkets run 24/7 refrigeration loads of 80-200 kW baseline plus checkout, lighting, and HVAC. A 6-module cluster (193 kWh) handles evening demand charges on a 250 kW connection while reserving capacity for refrigeration backup — typical hold-up requirement 30 to 60 minutes. ToU arbitrage runs daily on the refrigeration baseload. Sizing depends on store class and local tariff.

Cold Storage & Cold Chain

Cold storage warehouses up to 1,500 m² and refrigerated logistics hubs need continuous power for chambers and dock systems. A 10 to 15 minute outage spoils inventory. A 3 to 6 module cluster (96 to 193 kWh) runs continuous ToU arbitrage on refrigeration baseload and switches to backup on grid loss. Indoor IP21 enclosure fits utility rooms adjacent to plant rooms. Hold time depends on cluster size and load.

Telecom & Edge Infrastructure

Telecom base stations, edge data nodes, and small ISP hubs need 24/7 power continuity for 5-30 kW loads. A 3-module cluster (96 kWh) provides 3 to 12 hours backup at full load — longer at partial loads. Daily ToU cycling on the active grid connection generates economic return alongside the backup reserve. DC-coupled deployment with site rectifiers is the most common architecture. Indoor IP21 fits standard telecom enclosures.

Small Industrial & Manufacturing

Workshop-scale metalworking, plastics, and light manufacturing facilities draw 100-400 kW with sharp process-driven peaks. A 6 to 15 module cluster (193-483 kWh) covers demand-charge management on a 500 kW connection and provides 15 to 45 minute backup for critical processes. PV self-consumption pairs naturally with rooftop solar on manufacturing roofs. Sizing depends on process load profile and backup criticality.

FREQUENTLY ASKED QUESTIONS

Questions from engineers, specifiers, and EPCs.

Can the modular cluster power a mid-sized hotel or office building?
Yes. A 6-module cluster (193 kWh, 768 V class) covers a 50-100 room hotel’s evening peak — typically 60-120 kW for 3 hours — with capacity remaining for backup of booking systems, lifts, and emergency lighting. For office buildings under 2,000 m², a 3 to 6 module cluster handles afternoon demand charges on a 100-200 kW connection. Sizing depends on tariff structure, demand profile, and whether backup is required. We provide a sizing worksheet on request to sales@henleypower.eu.
A typical 1,500-2,500 m² supermarket draws 80-200 kW baseline refrigeration plus 100-300 kW during operating hours. A 6 to 9 module cluster (193-290 kWh) covers evening demand-charge management on a 250-400 kW connection. For refrigeration backup during outages, the same cluster provides 30-60 minutes hold time at the refrigeration baseload — enough for short grid disturbances. Larger hold times require larger clusters. ToU arbitrage on refrigeration baseload runs daily and generates economic return.
Yes — DC fast-charging hubs are a strong fit. Three 150 kW chargers operating simultaneously draw 450 kW peak. A 6 to 9 module cluster (193-290 kWh) buffers those instantaneous spikes, charges between sessions, and reduces the required grid connection from 500+ kW to 200-300 kW. For 350 kW HPC hubs, scale cluster size with simultaneous-charging load. DC-coupled deployment minimises conversion losses between battery DC bus and charger DC output. Inverter selection depends on charger architecture.
Each module delivers 32.2 kWh at 25.6 V nominal. Modules connect in series strings to reach 768 V (30-module string) or 819 V (32-module string) cluster voltage. A 3-module minimum string gives 96.6 kWh. A 30-module string reaches 966 kWh. Multiple strings run in parallel for multi-MWh installations up to 78 modules total, reaching 2,511.6 kWh maximum cluster capacity.
8,000 cycles at 80% depth of discharge and 25 °C, tested to IEC 62619 method, 0.5 C-rate, EOL defined as 70% of nameplate retention. At 50% DoD, cycle life exceeds 10,000 cycles. Warranty period is 5 years standard plus 5 years extended, capped at whichever limit — years or cycle count — is reached first.
Yes — three topologies are supported. Mode A: cluster pairs with string PCS rated for 696–922 Vdc input (Sungrow SC, Sineng EP, Hopewind, and equivalents). Mode B: cluster pairs with a hybrid inverter combining PV input and battery DC bus on the same chassis — Deye, Goodwe, Sofar HYD, Victron MultiPlus, SMA Sunny Tripower-S. Mode C: multiple clusters paralleled at the DC bus, connected to a central PCS rated 630 kW to 2.5 MW. All three topologies have been deployed commercially with Henley Power battery modules.
