Trontek, an Indian energy technology company, has brought its EKOM storage cubes for commercial and industrial sites to REI Expo 2026 in Greater Noida, India. The liquid-cooled units are offered at 261 kWh and 125 kW, and at 418 kWh and 215 kW, and both of them can run off the grid and black-start a site.

Trontek is exhibiting its EKOM battery storage range at REI Expo 2026, at India Expo Mart in Greater Noida, Uttar Pradesh, India. A grey EKOM cabinet with orange trim has been placed at the front of the stand, which presents Trontek as India's leading energy technology company.
The datasheet that is handed out at the stand lists two sizes. The HESS-261kWh-125kW holds 261 kWh and delivers 125 kW at 832 V, while the larger HESS-418kWh-215kW holds 418 kWh and delivers 215 kW at 1,331.2 V. Both models are built on 314 Ah lithium iron phosphate cells.
Both cabinets are liquid-cooled, and Trontek puts their system efficiency at 90%. They carry an IP54 rating and pack-level aerosol fire suppression, they have been rated for temperatures of -30°C to 55°C, and they communicate over RS485, Ethernet and CAN.
An operator can run a unit either on the grid or off it, and if the grid fails, the cabinet can black-start the site on its own. Several cabinets can also be linked under one master unit, and a diagram on the datasheet shows them working alongside solar panels and DC fast chargers for electric vehicles.
