iBCM Series 
Modular Energy Storage Inverter

The BCM series is a key equipment for achieving AC/DC bidirectional conversion in energy storage systems. The BCM series adopts a three-level topology, which has the characteristics of high efficiency and low harmonics; Simultaneously adopting modular design greatly improves the convenience of installation and maintenance. The BCM series can be connected in parallel with multiple modules, with a maximum expansion of 500kW per machine. It has various control functions such as constant power, constant current, and constant voltage, and can operate in parallel/off grid mode. It is widely used in various scenarios such as power generation, grid, user, and microgrid.
