Sungrow releases its liquid cooled energy storage system PowerTitan 2.0

Sungrow, one of the global leading inverter and energy storage system supplier, has introduced its latest liquid cooled energy storage system PowerTitan 2.0 during Intersolar Europe. The next-generation system is designed to support grid stability, improve power quality, and offer an optimized LCOS for future projects.

The PowerTitan 2.0 is a professional integration of Sungrow’s power electronics, electrochemistry, and power grid support technologies. The latest innovation for the utility-scale energy storage market adopts a large battery cell capacity of 314Ah, integrates a string Power Conversion System (PCS) in the battery container, embeds Stem Cell Grid Tech, and features systematic liquid cooled temperature control. The all-in-one system significantly enhances the power density, making the 20-ft container able to be equipped with 5MWh batteries and 2.5MW PCS.

The PowerTitan 2.0 integrates battery modules and the string PCS in a 20-ft container. The string PCS can charge and discharge battery racks individually; therefore increasing the system’s discharged energy capacity by over 7% across its entire life cycle.

The system boasts a round-trip efficiency (RTE) of 89.5%, an enhancement of 2%, with its Cell to Grid technology (C2G), which simplifies the energy conversion method between DC and AC power.

By integrating the liquid cooled thermal management system, both PCS and battery modules inside the container can achieve balanced heat dissipation. Therefore, the PowerTitan 2.0 maintains a lower cell/module temperature difference of 2.5 degrees Celsius, which results in a 20-year system performance life and improved charging and discharging efficiency.

With artificial intelligence (AI) bionic thermal balance technology, the system can automatically switch to the appropriate heat dissipation method according to the battery and environment temperature, and system operation status. This technology ensures that the system’s energy consumption is reduced to 50kWh per day — 40% less than the industry standard average consumption.

In addition, the PowerTitan 2.0 is equipped with Stem Cell Grid Tech. This technology aims to improve grid stability and increase power quality, featuring leading technologies such as enhanced continuous high and low voltage ride through, multi-level broadband oscillation suppression, flexible inertia support, microsecond-level voltage construction, and gigawatt-level black start. With these technologies, the system can achieve a transition between high voltage ride through (HVRT) and low voltage ride through (LVRT) seamlessly, reach resonance adaptive in 0.15Hz-2.5kHz, and restore the power supply of the local grid when the voltage fluctuation is under 2%.
