CLOU Electronics has introduced its latest Aqua-C2.5 liquid-cooled energy storage system at the 2024 edition of RE+ in Anaheim, USA. The next-generation system is designed to support grid stability, improve renewable power quality and deliver optimized LCOS for future energy storage projects.
The Aqua-C2.5 represents CLOU’s cutting-edge innovation for the utility-scale energy storage market, featuring a large 314/320Ah LFP battery cell capacity. The system is available in two versions: High Voltage Box and String PCS, providing flexibility to suit different project needs. The Aqua-C2.5 integrates long battery modules in a compact 20-ft container, significantly enhancing power density and enabling it to reach a 5MWh+ nominal capacity.
Both High Voltage Box and String PCS versions enable precise charging and discharging of individual battery racks, maximizing the system’s overall round-trip efficiency (RTE) by streamlining energy conversion between DC and AC, boosting the system’s energy discharge capacity over its full lifecycle.
Additionally, the modular design of both the battery pack and PCS simplifies operation and maintenance (O&M), reducing time and costs while ensuring high system availability. Features such as automatic state of charge (SOC) calibration also reduce power plant upgrade times.
A standout feature of Aqua-C2.5 is its advanced bionic thermal management system. This system automatically adapts to the battery’s operational and environmental conditions, ensuring optimal heat dissipation across both the PCS and battery modules inside the container. With a cell/module temperature difference of just 2.5 degrees Celsius, the system is built for long-term performance, offering a 20-year operational life with improved charging and discharging efficiency.
The Aqua-C2.5 is also engineered for durability with an impressive C5 anti-corrosion rating and IP55 protection making it suitable for operation in 0-95% (non-condensing) humidity and temperature ranges of -30℃ to 50℃ (optional -35℃).
The product has already achieved multiple certifications, including CE, UL1973, UL9540A, UL9540, IEC62619, IEC63056, IEC62477-1, UN38.3, NFPA855 and NEC, also passing the rigorous IEEE693 seismic test.
