CTECHI ESS125KW/261KWh Split-Type Liquid-Cooled Commercial & Industrial BESS Solar Battery Energy Storage System

The CTECHI ESS125KW/261KWh split-type liquid-cooled energy storage system stands at the pinnacle of CTECHI's split-cabinet product portfolio. Engineered for mission-critical commercial and industrial applications where performance cannot be compromised, this system combines a 52S high-voltage battery architecture with 5 series-connected 314Ah LFP packs to deliver 832V nominal voltage and 261kWh total capacity. The defining differentiator is the active liquid cooling system — a closed-loop glycol-based thermal management solution that maintains every cell within a tight ±2°C temperature band, eliminating the performance-robbing thermal gradients that plague air-cooled alternatives. This translates directly to higher sustained power output (125kW continuous), longer cycle life (projected 8,000+ cycles at 0.5C/0.5C), and the ability to operate at full rated power in ambient temperatures up to 50°C without derating. The 125kW SiC hybrid inverter completes the system with industry-leading 98.5% efficiency and full grid-support functionality. For enterprises pursuing aggressive energy cost reduction, carbon neutrality targets, or participation in grid ancillary service markets, the ESS125KW/261KWh represents the definitive liquid-cooled split-type solution.
