Product Summary:

The OMNI-260 ESS is a compact, all-in-one 261kWh industrial and commercial energy storage cabinet designed for microgrids, backup power systems, solar-storage applications, peak shaving, and distributed renewable energy integration. Built for both on-grid and off-grid operation, this system combines battery packs, BMS, PCS, EMS, liquid cooling, and fire suppression into a single standardized outdoor cabinet for reliable, high-efficiency energy storage. Powered by LFP 3.2V 314Ah cells, the OMNI-260 delivers stable, long-lasting performance with a rated 125kW PCS and a DC voltage range of 728V–949V. Its integrated bidirectional PCS supports seamless charge and discharge operation, while intelligent energy management enables optimized scheduling, dynamic load response, and dependable power delivery across commercial and industrial environments.

Designed for safety, durability, and scalable deployment, the OMNI-260 features a multi-level thermal suppression system with active early warning, smoke and temperature sensing, combustible gas detection, cabinet-level fire suppression, external water fire suppression, explosion-proof exhaust, and blow-off valve protection. With IP55-rated outdoor protection, liquid thermal management, industrial-grade circuit protection, and flexible parallel expansion, the OMNI-260 is built to support demanding energy storage applications with confidence.
