Overview
This commercial energy storage cabinet uses advanced 314 Ah LFP cells and a patented liquid-cooling design at pack level for consistent temperatures from cell to cell. A 125 kW hybrid inverter is built in, with zero heat transfer between the inverter and the cells for stability and a longer life. It switches from on-grid to off-grid in under 10 ms, expands up to 1.25 MW / 15.66 MWh, and supports remote monitoring and OTA upgrades through the JUN-HAN StorageCloud app.
