The ESG series is a cabinet type energy storage system developed by INJET New Energy for industrial and commercial application scenarios. It adopts a modular design concept and integrates batteries, battery management systems (BMS), energy storage converters (PCS), energy management systems (EMS), fire protection systems, and temperature control systems into standard cabinets. It has high integration, safety, and economy, and is a true ALL-IN-ONE energy storage system. The iESG series can be widely used in scenarios such as peak shaving and valley filling, demand management, optical storage and charging microgrids, backup power sources, and dynamic expansion.
