Emfex Energy showcased its Flux 261 ESS for C&I applications
It measures 1,350 × 1,326 × 2,180 mm and includes a storage section and a PCS
By connecting eight units in parallel, the cumulative storage capacity can reach 2 MWh
Gujarat-based energy storage system (ESS) maker Emfex Energy promoted its Flux 261 ESS at The Battery Show India 2026. It targets commercial & industrial (C&I) use cases, including providing uninterrupted power to critical loads, renewable energy integration, EV charging support, and UPS + diesel generator (DG) replacement.
Equipped with five 52.2 kWh lithium-iron phosphate (LFP) battery units, it offers a total storage capacity of 261.25 kWh with a nominal voltage of 832 V DC within a corresponding operating window of 728 to 936 V. Each unit is rated for 0.5P C-rate. These units are mounted on one another with a footprint of 1.69 m² (cabinet dimensions: 1,350 × 1,326 mm; W × D) and a height of 2,180 mm (H), making the ESS suitable for space-constrained C&I sites. This tall cabinet also features a built-in 125 kW power conversion system (PCS) for grid pairing at 400 V AC. It is rated for a full-load charging/discharging current of 180 A, and the system supports up to two cycles daily.
The product datasheet specifies a hybrid thermal regulation method with liquid cooling (for the storage section) and air cooling (for the PCS), with an operating temperature range of -20 to +45°C. It has an IP55 rating and supports up to eight units connected in parallel for a cumulative capacity of 2 MWh.
