Pylontech L260 OMNI 260 kWh is a high-performance commercial All-In-One energy storage system, liquid-cooled and AC-coupled, equipped with a 125 kW Power Conversion System (PCS). It is designed for demanding commercial and industrial applications where high energy density, long cycle life, and stable operation across a wide temperature range are essential.

The integrated outdoor cabinet enables bidirectional energy transfer between the DC battery system and the AC grid through AC/DC conversion. An advanced EMS supports intelligent control strategies including battery charge and discharge management, grid load tracking, energy arbitrage, demand response, and off-grid/backup operation.

Liquid cooling, high ingress protection of battery modules, and comprehensive safety systems make this solution ideal for mission-critical energy storage projects.

Main system functions:

• Peak shaving and valley filling for energy cost optimization

• Anti-backflow protection
