Description
48% higher capacity in a standard 19-inch rack footprint.
Pylontech H48074 is a 3.552 kWh high-density high-voltage series rack-mount LFP battery module operating at 48 V nominal (74 Ah), engineered to build 240 V to 864 V high-voltage storage columns for Pylontech PowerCube-X2 and PowerCube-H2 commercial systems.
3.552 kWh / 74 Ah High-Energy Density
Delivers 48% more energy than standard H48050 modules in the same rack footprint, reducing total cabinet count across commercial projects.
High-Voltage Series Rack Architecture
Connects in long series strings (from 5 up to 18 modules) to build high-efficiency 240 V to 864 V DC commercial storage banks.
Standard 19-Inch Rack Form Factor (3U)
Slides neatly into PowerCube server-style cabinets with front-facing high-voltage DC terminals and communication ports.
Intelligent Sub-BMS Telemetry Integration
Continuously monitors individual cell voltages, temperatures, and state-of-charge, reporting to the central master controller.
More product details
Commercial battery rooms have strict floor space limitations. The H48074 packs 74 Ah prismatic cells into a 3U rack chassis, enabling PowerCube-H2 cabinets to store up to 63.9 kWh per rack.
- Connects 5 to 18 modules in series within a single PowerCube rack cabinet.
- Direct high-voltage pairing cuts internal conversion steps, delivering peak round-trip efficiency.
- Front-facing Amphenol high-voltage DC terminals ensure secure, error-free series jumper connections.

High thermal stability with module-level sub-BMS monitoring.
Built with automotive-grade 74 Ah prismatic LFP cells in a 15S series configuration, each module features integrated sub-BMS electronics that report cell telemetry to the SC0500/SC1000 master controller. Integrated cell-level temperature sensors and active voltage balancing prevent localized degradation. Deep 95% depth-of-discharge provides 3.374 kWh of usable energy per module across thousands of daily cycles. Standard 442 × 390 × 132 mm (3U) dimensions slide into 19-inch industrial storage racks.
Sits 132 mm high on the shared rails
The brick shares the 442 by 390 mm footprint. 132 mm of height takes one slot.
Takes a 32 kg lift into the slot
32 kg is the lift for this 74 Ah housing. The rails take the weight.
Fits X-series and H-series racks
The same 74 Ah brick slides into an X-series 600 V rack or an H-series 1000 V rack.
Technical data
High-density series storage engineered for PowerCube-X2 and H2 commercial storage systems.
3.55 kWh / 74 Ah high-density rack module for high-capacity PowerCube installations.
Designed to increase energy density in PowerCube-X2 and PowerCube-H2 cabinets, the H48074 module provides 3.552 kWh of LFP storage at 48 V nominal. It delivers 48% more capacity than standard H48050 bricks in the same rack footprint, reducing total cabinet count in multi-hundred kilowatt-hour commercial projects.

Can I mix H48050 (50 Ah) and H48074 (74 Ah) modules in the same PowerCube series rack?
No. All modules in a series string must have identical capacity ratings. Because modules are connected in SERIES, current flows equally through every pack. Mixing 50 Ah and 74 Ah modules would severely bottleneck the 74 Ah packs to the capacity of the 50 Ah units, leading to cell degradation and BMS fault tripping.
