The OMNI-260 is a containerized commercial and industrial energy storage system rated at 261kWh capacity and 125kW power output. It is built for facility backup power and grid-tied project sites, not for residential or mobile use.
Note: Full specifications, wiring diagrams, and certifications for this system are available on the Resources tab of this page. Review those documents before you plan an install.
What This System Is
The OMNI-260 is BigBattery's C&I-class energy storage system, built around a 261kWh usable capacity and a 125kW power rating. This is a grid-tied, UL-classified product line intended for commercial facilities, project sites, and similar large-scale backup or load-shifting applications. It is not a golf cart, RV, or marine battery, and it is not sized or packaged for DIY residential off-grid sheds.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate) — the manufacturer data provided does not break out individual cell specifications, module counts, or internal group sizing for this containerized system. [NEEDS VERIFICATION]
Product type: UL Grid-Tied C&I Energy Storage System.
Wiring & Configuration Limits
The DATA provided for this listing does not include series/parallel stacking limits, inverter pairing specifications, or communication protocol details for the OMNI-260. [NEEDS VERIFICATION] Do not attempt to wire, stack, or integrate this system based on assumptions — confirm exact configuration limits with BigBattery documentation before ordering.
Pro-Installer Tip
Large-format LiFePO4 systems like the OMNI-260 are commonly installed by teams who assume that because the chemistry is lithium, the discharge and charge limits are as forgiving as a small residential battery. They are not — a 125kW system has a fixed power ceiling, and exceeding it repeatedly can trigger BMS lockout across the whole bank rather than a single module. Over time, this kind of thermal and electrical stress on a subset of cells creates imbalance across the array, and imbalance is what shortens cycle life on systems this large. Before commissioning, verify actual continuous discharge and charge limits with a shunt-based monitoring system tied into the facility's energy management platform, not just the inverter's onboard readout. As a professional standard, plan your daily cycling around the system's rated depth of discharge rather than running it to the edge on a routine basis — occasional deep cycles are normal, but daily 100% DoD cycling on a system this size should be a deliberate design decision, not an accident of undersizing.
