CNTE Unveils STAR X Liquid-Cooled Storage System in Munich

The system streamlines installation by combining battery modules and liquid-cooled grid-forming PCS within one enclosure. By moving DC cabling inside the unit and completing factory pre-commissioning before shipment, the company aims to reduce the typical timeline for large-scale energy projects. Each unit is built around CATL’s third-generation 530Ah cells, which the manufacturer claims can sustain over 10,000 cycles while maintaining 70% state of health.

Operational efficiency is managed through cluster-level intelligent control, which isolates faults to keep system availability above 99%. This granular management reduces circulation loss and improves discharge capacity by 6% over the product's lifecycle. With a weight limit of 45 tons, the cabinet is designed for standard international shipping, allowing for configurations between 1MW and 2.8MW depending on the specific duration requirements of the utility or commercial site.

Maintenance is shifted away from manual onsite intervention toward software-driven oversight. Features such as AI-powered fault diagnosis, OTA remote upgrades, and automatic SOC calibration minimize the need for technicians on the ground. Safety remains a central focus of the engineering, featuring a multi-level protection architecture that monitors the system from the individual cell level up to the full container, supported by continuous online insulation tracking.
