SINEXCEL has supplied the power conversion infrastructure for the first 300 MW/1200 MWh phase of China’s largest electrochemical energy storage project in Shenzhen. This phase includes 240 battery containers and 60 prefabricated cabins housing 180 units of SINEXCEL’s 1725 kW PCS. The PCS platform delivers 98.5% efficiency, supports multi-string configurations, and offers a 10 ms response time. These components collectively move the project toward its full 600 MW/2400 MWh buildout.

SINEXCEL, a Shenzhen-based energy storage and power-electronics manufacturer, has supplied the power conversion infrastructure for the first 300 MW/1200 MWh phase of China’s largest electrochemical energy storage station. This phase represents half of the planned 600 MW/2400 MWh facility, to be deployed across two project locations, has now been successfully commissioned.
The initial phase includes 240 battery containers and 60 prefabricated cabins configured to support large-scale grid operations. SINEXCEL supplied 60 prefabricated cabins equipped with 180 units of its 1,725-kW utility-scale Power Conversion System (PCS). According to SINEXCEL, the PCS platform reports a peak efficiency of 98.5% and supports multi-string operation. Its design enables battery protection through independent string control. The system allows flexible configuration with one, two, four, or eight strings.
The system’s combined AC/DC output simplifies system control and reduces integration steps during installation and future upgrades. The system features a 10 ms response time that enables real-time grid support,and uses IP54-rated cabinets for reliable outdoor operation.
SINEXCEL stated that commissioning this first 300 MW phase establishes the foundation for full deployment of the 600 MW project. The complete energy storage complex is expected to operate as part of an integrated wind–solar–thermal–storage–transmission model designed to maximize renewable energy utilization and grid flexibility. The company reports more than 12 GW of deployed storage capacity globally and over 5,000 system deployments across utility-scale, C&I, and microgrid applications.
