Sungrow Named Finalist for the ees AWARD with its C&I Liquid Cooled ESS PowerStack


Sungrow, the global leading inverter and energy storage system solution supplier, announced its selection as a finalist in the highly esteemed ees AWARD 2023 competition. The recognization is for Sungrow’s liquid cooled energy storage system (ESS), the PowerStack ST500CP, which caters specifically to the commercial and industrial (C&I) energy storage market and serves as a catalyst for the ongoing energy transition.


The ees AWARD is presented by the organizer of international exhibition series for batteries and energy storage systems – ees (electrical energy storage). The energy award pays tribute to pioneering products and solutions for stationary and mobile electrical energy storage systems. The range of innovations encompasses the entire value-added chain of innovative battery and energy storage technologies – from components to concrete applications and business models.


The PowerStack ST500CP is a compact C&I ESS, featuring an output of 250kW and is available with battery capacity between 537kWh and 1,146kWh. The system is a professional integration of Sungrow’s power electronics, electrochemistry, and grid support technologies. The liquid cooling concept reduces the temperature management energy demand by 30 percent.

Sungrow was able to reduce the temperature difference between the individual cells to less than 2.5°C, resulting in more consistent cell aging and extending the battery modules’ service life by two years. Accordingly, the high level of pre-fabrication and the option to run the cables aboveground have reduced the installation time by around 60%, making it a highly efficient solution.

To learn more about PowerStack, onsite visitors can visit the Sungrow booth B3.310 and B3.410 at Intersolar Europe 2023 in June 14-16.
