Product Features
Large Capacity
Single Unit Capacity 10MWh~70MWh; With strong grid support capability
High Efficiency
Zero series capacity loss, zero parallel circulating current; overall cycle efficiency reaches 87%~90%.
Low Cost
By FCCS board system replaces “ BMS+PCS+ transformer”, significantly reducing system cost.
Low O&M
PACK Plug and play, entire station operates continuously
High Safety
1. Electrical topology intrinsic safety design, PACK level charge and discharge control, fundamentally preventing batteries from operating in overcharge or overdischarge states;
2. PACK level active fault isolation, preventing faulty or sub-healthy batteries from operating with issues;
3. Flexible interconnection within and between battery clusters, full current (≥157A) within and between clusters balancing.
