Description
ST225kWh-110kW-2h PowerStack | Sungrow C&I Energy Storage System
MAIN FEATURES
Highly integrated C&I system (2 hours) with compact design, intelligent liquid cooling, and seamless parallel connection. Reduces system heat loss by 33% thanks to the AI thermal balance, improving efficiency and extending lifespan. Multi-layer safety: early detection of thermal runaway, fire suppression, and overcurrent protection at PACK, RACK, and PCS levels.
Rated power of 110 kW, storage capacity of 229 kWh, and maximum efficiency of 98.6%. Compatible with on-grid and off-grid operation using an additional transformer cabinet.
Remote monitoring and management via iSolarCloud (App or Web).
