Gotion ESC-R125-261-CE 261 kWh Industrial Energy Storage System 125 kW

The Gotion ESC-R125-261-CE is an all-in-one industrial and commercial energy storage system with a nominal capacity of 261 kWh and rated power of 125 kW. It features LFP (lithium iron phosphate) cells in a 1P52S×5 configuration with a charge/discharge rate of 0.5C at 25°C, delivering over 8000 cycles at 90% depth of discharge. The system operates across a voltage range of 728–936 V and achieves 99% power conversion efficiency.

The cabinet unit integrates liquid-cooled battery packs with intelligent temperature control, supporting operation across -30 to +50°C (with derating above 45°C) and altitudes up to 3000 m (with derating above 2000 m). The IP55-rated cabinet is fire-resistant (1.5 h) with multi-level electrical control and aerosol fire suppression. Dimensions are 1120 × 1350 × 2420 mm; unit weight is 2.6 tonnes.

Remote operation and maintenance capabilities include cloud-side coordination, remote monitoring, early warning, fault analysis, and software upgrades. The system supports modular, multi-machine parallel deployment with Modbus and MQTT communication protocols over RS485 and dual Ethernet ports. Certifications include GB/T36276, IEC62619, IEC62477, IEC61000, UN38.3, and UL9540A.
