About this item
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.

Frequently Asked Questions
What certifications does a C&I battery storage system need?
Commercial installations typically require UL 9540 for the system, UL 1973 for the battery, UL 9540A fire testing, and NFPA 855 compliance for installation. The OMNI-260 is designed around UL1973, UL9540A, UL9540, IEEE1547, UL1741SB, NFPA68, NFPA69, NFPA855, CE and UN38.3.
Can the OMNI-260 run off-grid?
Yes. It supports both on-grid and off-grid operation, with an integrated 125kW bidirectional PCS handling charge and discharge. That makes it suitable for microgrids and islanded facilities as well as grid-tied peak shaving and backup.
How many OMNI-260 cabinets can I parallel?
The system supports flexible parallel expansion, so multiple cabinets can be combined for larger deployments. Each cabinet is 261kWh, so scaling is done in 261kWh increments. Cloud-based fleet management supports multi-site monitoring across deployments.
What is included in the cabinet?
Battery packs, BMS, PCS, EMS, liquid cooling and fire suppression are all integrated into a single standardised outdoor cabinet. The pre-integrated layout is what reduces setup complexity compared with assembling components from separate vendors.
Why liquid cooling rather than air cooling?
Liquid thermal management holds cell temperature more consistently under sustained high-power cycling, which protects cycle life and keeps performance stable. The OMNI-260 is rated for 8,000+ cycles at 25±3°C to 70% end of life, and runs at 64dB or less.
