Fully Integrated System Design

Efficient Liquid Cooling: Uniform temperature distribution (?T ? 2.5 }C) protects the battery cells and increases their lifespan.

Maximum Safety: AI-supported cell monitoring, multi-stage overcurrent protection, and an integrated fire protection concept (including gas detector, smoke detector, and aerosol system).

Powerful and Robust: 110 kW nominal power output with a system efficiency of up to 98.5%.

Parallel Operation: Supports up to 25 units in parallel operation (grid-connected) for the 2-hour system, providing a capacity of up to 5.7 MWh.

Smart Monitoring: Via the iSolarCloud app with remote maintenance, firmware updates, and real-time fault analysis.

The Sungrow PowerStack ST225kWh-110kW-2h is a powerful, fully integrated energy storage system for commercial and industrial applications. With a usable capacity of 225 kWh and a power output of 110 kW (discharge time: 2 hours), the storage system offers an ideal balance of efficiency, safety, and flexibility.
