BigBattery is proud to announce the first CNI all-in-one system, The OMNI-250, a purpose-built 250kWh Commercial & Industrial energy storage solution designed to reduce demand costs, stabilize operations, and strengthen site resilience across real-world CNI environments. Built around Tier 1 LiFePO₄ (LFP) cells, advanced liquid thermal management, and an integrated 125kW liquid-cooled PCS, Omni-250 delivers consistent performance in a rugged, outdoor-ready cabinet—making it an ROI-driven answer to the most common CNI energy challenges. For Warehousing & Logistics (including cold storage), it tackles big, peaky loads and long operating hours by enabling peak shaving and time-of-use load shifting to reduce demand charges while smoothing heavy starts and cycling from HVAC, refrigeration, and conveyor systems. In Manufacturing & Light Industrial, Omni-250 buffers machinery-driven demand spikes, supporting demand-charge reduction, power quality support, and backup resilience to keep process loads protected when the grid isn’t cooperative. And for Commercial Buildings & Campuses—office, retail, mixed-use, schools, universities, and municipal facilities—it’s a straightforward way to combine backup power with demand management, and it pairs naturally with solar for a more complete, future-proof energy strategy.
