SUNGROW POWER SUPPLY (China) was named a winner of the ees AWARD 2023 for its Sungrow PowerStack ST500CP liquid cooling energy storage system.


SUNGROW POWER SUPPLY from China is one of the world's leading manufacturers of solar inverters and battery storage systems. The new PowerStack ST500CP is a powerful modular energy storage system for commercial and industrial applications. It has an output of up to 250 kW and a storage capacity of between 537 and 1,146 kilowatt hours (kWh).

The pre-installed design, the above ground cabling and the wireless control of the energy management system make for easy installation and commissioning, saving up to 60 percent installation time.

Internal liquid cooling reduces the energy required for thermal management by 30 percent and keeps the temperature differences between individual cells at just ≤2.5°C. According to the manufacturer, this innovation reduces irregular cell aging and can extend the system’s life span by up to two years.

The panel found this a compelling product innovation, and one of the winners of the evening.
