Product overview

For loads that
never sit still.

This next-generation smart liquid-cooled all-in-one cabinet delivers 250 kW of power and 488 kWh of capacity — purpose-built for commercial, industrial and grid-scale applications where reliability, efficiency and deployment flexibility matter most.

Built with industry-leading technology, it lets businesses harness clean energy, reduce operating costs and move faster toward energy independence. 587 Ah cells mean fewer connections inside the cabinet, and fewer failure points to monitor over a ten-year life.

Key highlights

Maximise performance,
minimise costs.

A higher-power platform changes the economics: fewer cabinets per megawatt, less balance of plant, and a shorter installation programme.

Flexible deployment

AC-side independent architecture enables modular expansion and adaptable system design for diverse projects.

Energy efficient

No parallel operation required — minimised conversion losses deliver higher overall system efficiency.

Lightweight design

Monolithic structure enables faster handling, streamlined installation and reduced logistical complexity.

≥98.5% converter efficiency

High-efficiency conversion with THDi below 2% keeps more of every cycle and protects power quality.

Cell delta ≤ 5 °C

Precision liquid cooling maintains uniform cell temperatures, significantly extending battery lifespan.

IP54 cabinet, IP67 packs

Full cabinet IP54 rating with IP67 battery packs — deploy confidently indoors or outdoors.
