5MWh Liquid-Cooled Energy Storage Battery Container (DC-side)
5MWh Liquid-Cooled Energy Storage Battery Container (DC-side)
Product Description
This 5MWh liquid-cooled energy storage battery container (DC-side) adopts a professional 12-cluster integrated design, with a single cluster capacity of 418kWh and a wide DC output voltage range of 1000–1500V, specially built for large‑scale commercial and industrial energy storage scenarios. When matched with a 2.5MW C&I containerized string PCS MV skid, it forms a complete and high‑performance battery energy storage system (BESS). The system features advanced liquid cooling technology, intelligent thermal control, and multi‑cluster management architecture, which effectively improve energy density, extend battery cycle life, reduce power loss, and optimize overall costs. It is widely used in large industrial and commercial energy storage plants to stabilize power fluctuations, improve energy utilization efficiency, and provide safe, reliable, and efficient energy storage support for large‑scale renewable energy grid connection and peak shaving applications.
