China’s largest electrochemical energy storage project—600MW/2400MWh—has completed the installation of all storage cabins at its first site, marking a key milestone as it enters the electrical commissioning phase, with SINEXCEL powering the national-level project with its utility-scale 1725kW Power Conversion System (PCS).
This is China’s first ultra-high voltage (UHV ) transmission project, integrating wind, solar, thermal and storage, the site including 240 battery containers and 60 PCS skids. Once operational, the project will integrate an annual 840 GWh of renewable energy into the grid.
SINEXCEL has also supported a 220MW/880MWh storage project connected to the grid in Ningxia, integrating solar and storage to solve renewable energy curtailment, enhance grid stability and energy shifting. The station is expected to supply an annual 200 GWh of electricity.
SINEXCEL is contributing to these two projects with its 1725kWPCS. Designed to enhance grid stability, the product features a modular architecture scalable from 215kW to 1.72MW per unit. It combines advantages for both centralized and string configurations, supports diverse battery types and enables flexible deployment across various storage scenarios, including large C&I, microgrids and front-of-the-meter applications.
With a peak efficiency of up to 98.5%, the PCS features advanced multi-string technology for enhanced battery protection and supports flexible configurations with 1, 2, 4 or 8 battery strings. Its combined AC/DC output simplifies control and expansion, while NEMA 3R-rated cabinets ensure outdoor durability. A rapid 10ms response time supports real-time grid balancing and the product meets major compliance standards in North America, Europe, Australia, Japan and China.
With a global footprint spanning 40+ countries and over 5,000 deployments, SINEXCEL has to date installed over 12GW of storage capacity, delivering solutions for utility-scale, C&I and microgrid applications.
