The first phase (300 MW/1200 MWh) of China’s largest electrochemical energy storage station has been commissioned, powered by SINEXCEL’s 1725kW utility-scale Power Conversion System (PCS), a milestone marking a critical step toward full-capacity operation, significantly enhancing grid stability and accelerating clean-energy adoption.
The site is one of two project locations for the 600MW/2400MWh storage station and incorporates 240 battery containers and 60 prefabricated cabin units. Once the entire project is complete, it will form an integrated “wind–solar–thermal–storage–transmission” model that maximizes renewable-energy utilization and enhances overall system flexibility.
The 60 prefabricated cabins supplied by SINEXCEL are equipped with 180 units of the company’s 1725kW PCS. Delivering peak efficiency of up to 98.5%, the PCS employs advanced multi-string technology for enhanced battery protection and supports flexible configurations of 1, 2, 4 or 8 battery strings. Its combined AC/DC output simplifies system control and future expansion, while IP54-rated cabinets ensure reliable outdoor operation. With a rapid 10 ms response time for real-time grid balancing, the product already meets major compliance standards across North America, Europe, Australia, Japan and China.
With a global footprint now spanning over 40 countries and more than 5,000 worldwide deployments, SINEXCEL has installed over 12GW of storage capacity, delivering solutions for utility-scale, C&I and microgrid applications.
