Product Summary:

The OMNI-250 is a 250 kWh all-in-one energy storage system engineered for Commercial & Industrial environments where demand volatility, high load profiles, and uptime requirements directly impact operating costs. Designed for measurable performance,

the system supports peak demand reduction, load shifting, and on-site resilience within a fully integrated platform.

Built with Tier 1 LiFePO₄ (LFP) cells, advanced liquid thermal management, and a 125 kW liquid-cooled power conversion system (PCS), the OMNI-250 is optimized for thermal stability, repeatable output, and long service life. Its outdoor-rated enclosure and integrated architecture streamline deployment while supporting scalable energy strategies, including solar integration. 

Key Features & Application Fit

  • 250 kWh Energy Capacity – Sized for demand charge reduction, peak shaving, and time-of-use optimization in mid-to-large C&I facilities

  • 125 kW Liquid-Cooled PCS – Supports high-load applications and consistent power delivery under demanding operating conditions

  • Tier 1 LiFePO₄ (LFP) Cells – Enhanced safety profile, long cycle life, and stable performance for daily cycling environments

  • Advanced Liquid Thermal Management – Maintains optimal operating temperatures in high-ambient or heavy-duty installations

  • Integrated All-in-One Architecture – Reduces installation complexity and footprint compared to component-based systems

  • Outdoor-Rated Enclosure – Suitable for exterior deployment across industrial and commercial sites

  • Solar-Ready Integration – Pairs with on-site PV for load management, resilience, and long-term energy cost control

Best Fit Applications

  • Warehousing & Logistics (including cold storage)

  • Manufacturing & Light Industrial facilities

  • Commercial buildings, campuses, and municipal infrastructure

BigBattery’s C&I All-In-One Energy Storage System

Stabilizing Power When & Where You Need It

For utility-scale solar and wind projects, the Omni-250 provides a reliable buffer between intermittent generation and real-world grid demand. With 250kWh of storage and a 125kW power conversion system, it enables frequency regulation, renewable smoothing, and dispatchable energy delivery.

Its Tier-1 LFP design and liquid cooling ensure stable long-duration performance even in harsh outdoor environments, making it ideal for grid-edge deployments and renewable infrastructure upgrades.

Powering Plans Into Production

For energy-intensive facilities, demand spikes are expensive. The Omni-250 is purpose-built for peak shaving and load shifting, delivering up to 125kW of output power to reduce utility demand charges without interrupting operations.

With quiet operation (~75dB) and an IP54-rated enclosure, the system integrates cleanly into industrial campuses, warehouses, and high-load commercial facilities — all while providing backup protection during outages.

Reliable Energy For Any Project

Remote infrastructure projects — including mining, defense, telecom, and off-grid industrial operations — require storage that performs under stress. The Omni-250 operates from -22°F to 131°F, supports rugged installation up to high altitudes, and includes advanced fire suppression for mission-critical reliability.

Its modular cabinet design allows project developers to scale storage capacity quickly across multiple nodes, forming the backbone of resilient microgrid ecosystems.
