The Dyness DH800Y is an 838 kWh fully liquid-cooled Battery Energy Storage System housed in a standard 20-foot shipping container, designed for large industrial campuses, commercial parks, and utility-scale solar+storage projects. All systems — battery racks, liquid cooling plant, BMS, and power electronics — arrive pre-assembled in the container. Site installation involves connecting power cables and commissioning software. Up to 8 units can be networked together. 90% round-trip efficiency ensures that most of the solar energy going in comes back out as usable electricity. Designed for a 10-year service life with minimal maintenance requirements.
