The LES-261L130-PS is a high-capacity liquid-cooled PV and energy storage solution designed for commercial and industrial applications requiring high power density, flexible expansion, and enhanced safety. With a single-cabinet energy capacity of up to 261 kWh and a rated output power of 130 kW, it delivers reliable performance for grid-connected and off-grid operation.
The system supports 100% three-phase unbalanced loads, ensuring stable power supply under complex load conditions. A high-power PV access design with multiple MPPTs enables efficient integration of large-scale photovoltaic systems, while parallel operation of multiple cabinets allows flexible capacity and power expansion to meet evolving project demands.
Engineered for safety and thermal efficiency, the LES-261L130-PS features a PACK-level liquid-cooled runner design for highly efficient heat dissipation, combined with PACK- and cabinet-level fire protection using aerosol and water-based systems. An intelligent dehumidification function further reduces condensation risks, enhancing long-term system reliability.
Designed for intelligent operation and simplified maintenance, the system supports remote monitoring, cloud-based operation and maintenance, and online upgrades. With an IP54-rated enclosure, wide operating temperature range, and integrated transportation design, the LES-261L130-PS offers easy installation, fast deployment, and low lifecycle cost.
Reliable, scalable, and intelligently managed, the LES-261L130-PS is an ideal solution for C&I PV + ESS projects, microgrids, peak shaving, and backup power applications.
