Sungrow PowerStack – C&I Storage


The Sungrow PowerStack is an advanced energy storage system designed for commercial and industrial applications, available in two configurations:

  • ST225kWh-110kW-2h: nominal capacity of 229 kWh and nominal power of 110 kW
  • ST455kWh-110kW-4h: nominal capacity of 458 kWh and nominal power of 110 kW

Advanced thermal management

The PowerStack uses an advanced liquid cooling system that ensures uniform heat dissipation with a temperature difference between cells ≤ 2.5°C, improving efficiency and durability. Thanks to an AI algorithm that controls thermal balance, the system reduces heat losses by 33% throughout the day.

Suitable for outdoor installations

Powerstack operates in a wide temperature range from -30°C to 50°C and is protected by an IP55 rated enclosure, making it suitable for outdoor installations.

Advanced safety

Intelligent cell health monitoring with immediate alarms to manage any thermal runways. Three-level overcurrent protection (PACK, RACK, PCS) and three-level fire protection design with precise alarms to prevent fires.

Flexibility and scalability

Ability to connect in parallel “side by side” to adapt to the specific needs of each site.

Intelligent management

Real-time monitoring via the iSolarCloud app or web platform, with alarm and troubleshooting capabilities. Wireless operation and remote updates help reduce operation and maintenance costs.
