Products Description

Off-grid Energy Storage Island Grid Balance Frequency Regulation Energy Self-consumption UN38.3 Container Scale 3.858MWh BESS
🛈
The #ECO-B20FT3858WS Lithium-ion battery cabinet uses an advanced liquid cooling system to keep the cabinet internal temperature difference less than 3°C, which improves the consistency of cell temperature and extends the battery life. The modular design makes the parallel solution more flexible and can be combined with centralized PCS to form an ESS with higher energy density.
