The LES-241L120 is a high-density, liquid-cooled energy storage cabinet designed for commercial and industrial applications requiring high power, superior safety, and intelligent operation. Integrating a 241.15 kWh battery system with 120 kW three-phase output, it supports both grid-connected and off-grid operation, delivering stable and high-quality power for complex load scenarios.
The system fully supports 100% three-phase unbalanced loads, ensuring reliable performance even under uneven or dynamic load conditions. Advanced remote monitoring, cloud-based operation, and online upgrades enable efficient system management throughout the entire lifecycle.
Safety and reliability are core to the LES-241L120 design. It features dual-level fire protection at both PACK and cabinet levels, combined with intelligent dehumidification to eliminate condensation risks in demanding environments. A PACK-level liquid-cooled runner design ensures efficient heat dissipation and stable battery operation, while the electrical compartment adopts air cooling to optimize overall system reliability.
Engineered for ease of deployment, the LES-241L120 offers flexible expansion, integrated transportation, and simplified installation and maintenance. Despite its high energy density, it requires less than 1.4 m² of floor space, making it ideal for space-constrained sites.
With IP54 protection, wide temperature tolerance, and robust safety systems, the LES-241L120 is a reliable, scalable, and intelligent energy storage solution for C&I ESS, microgrids, and distributed energy applications.
