125 kW / 261 kWh Smart Liquid-Cooled All-in-One Cabinet
AC-side independent architecture, a 1P260S LFP string and 125 kW of conversion in a 1150 mm-wide enclosure — under 1.7 m² of floor space, ready to energise as a single unit.
A single cabinet,
a complete power block.
Engineered for the demands of modern commercial, industrial and grid-scale applications, this 125 kW / 261 kWh cabinet pairs an advanced liquid-cooling architecture with high-efficiency power conversion — delivering superior thermal management, extended battery lifespan and seamless integration.
Because the AC side is independent, each unit stands alone on the bus: no master-slave coupling, no parallel losses between cabinets, and no need to re-engineer the plant when you add capacity later.
Engineered for excellence,
built for reliability.
Six characteristics that separate this cabinet from a conventional rack-and-PCS assembly.
Flexible deployment
AC-side independent architecture allows versatile site integration and rapid scalability.
Superior efficiency
Standalone operation eliminates parallel losses, maximising energy throughput and profitability.
Optimised logistics
Lightweight monolithic structure means rapid handling, streamlined installation and reduced site prep.
≥98% round-trip efficiency
Industry-leading system efficiency drives maximum revenue generation from every cycle.
Precision thermal management
Cell temperature delta held to ≤ 5 °C by liquid cooling, significantly extending battery lifecycle.
Robust protection
IP54 cabinet with IP67 battery packs for environmental resilience indoors and outdoors.
The numbers.
Full electrical, battery, efficiency and mechanical data. Values are nominal at 25 °C unless otherwise stated.
