Emfex Energy is exhibiting at REI Expo 2026 in Hall 18, at Booth B20, at India Expo Mart in Greater Noida, Uttar Pradesh, India. The company designs and builds battery storage systems and EV chargers at a 3 GWh plant in Surat, Gujarat. It is backed by the KP Sanghvi Group, which is known for its diamond and real-estate businesses, and by REM Electromach, a maker of power electronics.

The Flux range, which is set out in a brochure that can be reached through a QR card on the stand, is built on 314 Ah lithium iron phosphate cells with liquid cooling. The Flux 261 stores 261 kWh and delivers 125 kW, while the Flux 522 stores 522 kWh and delivers 250 kW; a Flux 418 cabinet has been placed between the two. Every system is sealed to IP55, its packs are rated IP67, and it carries C4 corrosion protection and an aerosol fire-suppression system.

For utility-scale sites, the company offers the Flux 5000, a 20-foot container that holds 5,015.96 kWh at 1,331.2 V DC and can be charged and discharged twice a day. The systems communicate with plant controllers over Modbus and IEC 104.

Emfex has also combined a 261 kWh battery with a 120 kW DC charger that carries two CCS2 guns. The unit has been designed to fast-charge electric vehicles at places where the grid connection is weak, such as highways and construction sites, and to serve as a charging point during emergencies.
