ESS-TRENE Liquid Cooling

  • All-in-One Liquid Cooling Cabinet

The ESS-TRENE Liquid Cooling system is a next-generation energy storage solution tailored for the Asian and African markets. It features a fully integrated modular design with factory pre-installation and debugging for true plug-and-play deployment. The system is powered by 3S full-stack self-researched technology, ensuring stable, lifecycle operation without the risks of multi-vendor compatibility. Intelligence is driven by the Solax AI cloud platform, enabling adaptive optimization and unmanned station management for reduced operational costs.

Product Advantage

The ESS-TRENE Liquid cooling unit delivers certified capacity and efficiency for high-demand applications. It is available in two configurations: 99.9kW / 261kWh and 125kW / 261kWh. The system achieves a maximum Round-Trip Efficiency (RTE) of ≥ 90%, ensuring high-performance energy conversion. Safety is enforced through real-time battery cell monitoring, providing a 7-day advance warning for thermal runaway risks. Protection is layered across four levels—PACK, cluster, PCS, and AC side—ensuring precise shutdown to minimize losses in the event of an anomaly.
