The LES-261L130 is a high-capacity, liquid-cooled energy storage system designed for demanding commercial and industrial applications. With 261 kWh of energy capacity and 130 kW three-phase output, it delivers stable power for grid-connected and off-grid operation, even under 100% unbalanced load conditions.
A PACK-level liquid-cooled runner design ensures efficient heat dissipation and long-term battery performance. System safety is enhanced through dual-level fire protection at both PACK and cabinet levels, combined with intelligent dehumidification to prevent condensation in humid environments.
Supporting remote monitoring, cloud-based O&M, and online upgrades, the system simplifies operation throughout its lifecycle. Its modular, cabinet-integrated design enables flexible expansion and easy installation and maintenance, making the LES-261L130 a reliable and scalable solution for modern C&I energy storage projects.
