125 kW / 418 kWh Smart Liquid-Cooled All-in-One Cabinet
The same 125 kW converter with 60% more energy behind it. A 1P416S string at 1331 Vdc nominal extends discharge time past three hours — built for longer peak windows and sites that cannot afford a short bridge through an outage.
Longer duration,
same footprint family.
Engineered for modern commercial, industrial and grid-scale applications, this cabinet combines a liquid-cooled thermal architecture with high-efficiency power conversion — delivering superior thermal management, extended battery lifespan and seamless integration.
Capacity is bought in energy, not power. Where the 261 kWh model handles a short evening peak, this 418 kWh unit carries a full three-hour window or a longer backup ride-through, with the same 125 kW converter and the same AC-side independent connection.
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.
