Description
The Sungrow PowerStack ST255CS-2H battery is an energy storage solution for medium to high-power professional photovoltaic and energy storage projects. This all-in-one system integrates the battery, power inverter, and BMS in a compact cabinet, ready for on-site deployment.
With a storage capacity of 255 kWh and a power output of 125 kVA, the PowerStack is designed to meet the needs of commercial, industrial, and network service applications. The inverter and BMS are natively integrated, while overall energy management relies on an external EMS, which is mandatory for each project.
The system uses liquid cooling, enabling uniform thermal management of the cells and operational stability suitable for intensive cycles. Monitoring and control are based on the iSolarCloud platform, providing centralized visibility into performance, operation, and maintenance.
KEY POINTS FOR PROFESSIONALS
• All-in-one solution with integrated battery, inverter and BMS.
