The first phase (300 MW/1,200 MWh) of China’s largest electrochemical energy storage station has been commissioned, featuring SINEXCEL’s 1,725 kW utility-scale Power Conversion System (PCS). This milestone paves the way for full-capacity operation, reinforcing grid stability and expediting the integration of renewable energy.
Situated at one of two sites forming the overall 600 MW/2,400 MWh storage complex, the Phase I deployment comprises 240 battery containers housed across 60 prefabricated cabins. When fully complete, the project will operate as an integrated “wind–solar–thermal–storage–transmission” model, maximizing renewable utilization and enhancing system flexibility.
SINEXCEL supplied 60 cabins each fitted with three PCS units—180 in total. The PCS delivers peak efficiency of 98.5% and leverages advanced multi-string architecture for robust battery protection. Configurable for 1, 2, 4 or 8 battery strings, the combined AC/DC output streamlines system control and future expansion. Housed in IP54-rated enclosures for dependable outdoor performance, the PCS responds within 10 milliseconds to support real-time grid balancing. It also meets major compliance standards across North America, Europe, Australia, Japan and China.
Since its founding in 2007, SINEXCEL has installed over 12 GW of energy storage capacity and deployed more than 5,000 systems worldwide, serving utility-scale, commercial and industrial, and microgrid applications. The company’s portfolio also includes EV charging solutions—140,000 chargers installed—and power quality offerings with nearly 20 million amperes of active harmonic filtering in service. Strategic partnerships with leading industry players reinforce SINEXCEL’s commitment to resilient, sustainable energy infrastructure.
Participation in this landmark project underscores SINEXCEL’s technical capabilities and supports China’s broader clean-energy and decarbonization objectives. The completed Phase I installation advances the stability and flexibility of the regional grid, setting the stage for full-scale operation.
