en.Wedoany.com Reported - Hyderabad-based Trex Energy has launched the REX series, a fully integrated 125 kW/261 kWh single-cabinet battery energy storage system (BESS) for commercial and industrial (C&I) applications. The system integrates liquid cooling, an energy management system (EMS), and an AC/DC integrated architecture, with dimensions smaller than 1700 mm × 1350 mm × 2200 mm and a weight under 3500 kg.
This BESS utilizes 261 kWh lithium iron phosphate (LFP) batteries with a nominal voltage of 832 V, a cell capacity of 314 Ah, a maximum DC voltage of 950 V, and a maximum input active power of 125 kW. The system supports both grid-connected and off-grid operation modes, operates in ambient temperatures ranging from -20°C to 55°C, and features an IP54 protection rating for dust and water resistance.
Roshan Shaik, Technical Director of Trex Energy, stated that liquid cooling, aerosol fire suppression, and intelligent cloud monitoring functions are all integrated into a single cabinet, providing customers with a reliable long-term energy storage solution. Compared to traditional air-cooled systems, liquid cooling technology maintains optimal cell temperatures under all operating conditions, significantly slowing battery degradation and extending lifespan.
The company noted that the BESS platform supports future capacity expansion through optional 100 kW maximum power point tracking (MPPT) and 200 kW static transfer switch (STS) modules.
The system is equipped with aerosol fire suppression protection, as well as overcharge, over-discharge, short circuit, and thermal event protection, ensuring safety under all operating conditions.
The integrated energy management system (EMS) features 4G connectivity and a 7-inch HMI touchscreen, enabling remote real-time monitoring, remote diagnostics, and cloud-based maintenance. The system is compatible with photovoltaic input, AC busbars, the grid, loads, and electric vehicle charging infrastructure.
