SolaX Power exhibited at REI Expo 2026 in Hall 14, at Booth C141, at India Expo Mart in Greater Noida, Uttar Pradesh, India. The company, which is based in Hangzhou, China, makes inverters and battery storage systems, and it had divided its stand between products for homes and products for commercial users. Its storage cabinet for commercial sites was placed at a corner of the stand, under a sign for the ESS-TRENE range.

The ESS-TRENE cabinet is an AC-coupled system, in which the batteries, the battery management system, the energy management system and the power conversion system have been housed in one enclosure. According to the company's product page, the 261 kWh model stores its energy in LFP cells of 314 Ah, operates at a nominal voltage of 832 V DC and delivers a rated output of 125 kW. Because each cabinet is pre-assembled and pre-commissioned at the factory, little work is required at the site, and further cabinets can be placed side by side when more capacity is needed.

The cells are cooled by liquid under an intelligent thermal management system, and the company states that the round-trip efficiency of the system reaches up to 90%. For safety, protection against overcurrent has been provided at four levels, namely the battery pack, the cluster, the power conversion system and the AC side, while the cell monitoring has been designed to warn of a short circuit up to seven days in advance. The enclosure has been rated IP55, and the system can be operated between -30°C and 55°C, although its output is derated above 45°C.

Stacked battery modules and a large string inverter had been set out beside the cabinet. Elsewhere on the stand, the company displayed its X3-FORTH PLUS string inverter, which is offered in ratings of 120 kW to 150 kW for commercial rooftops, together with wall-mounted inverters and batteries for homes.
