The Dyness DH200Y is a 232 kWh liquid-cooled Battery Energy Storage System built for industrial environments where high ambient temperatures would shorten the life of an air-cooled system. The PACK-level liquid cooling system maintains cell temperature uniformity within ±1.5°C, dramatically extending cell life compared to systems with hot spots. A compact 1.06 m² footprint makes it one of the most space-efficient large BESS cabinets available. Up to 10 units connect in parallel for 2.3 MWh total storage. IP40+PF S12D13 rated enclosure. Installation cost is reported to be 30% lower than comparable air-cooled alternatives due to the simplified external infrastructure. Designed for 1,000V DC bus architectures.
