1. Function description:
It is a bidirectional converter for charging and discharging batteries. When the battery is discharged, its output can be fed back to the grid. After the battery is charged, the battery is directly charged. This product USES double DSP full digital control, high efficiency, small volume. Using two-way DCDC technology and pure digital control technology, it has the characteristics of high output stability accuracy, rapid transient response, two-way energy flow, etc., and can simulate dynamic characteristics of power battery charge and discharge. It CAN be configured as an intelligent monitoring system with the host controller for remote real-time monitoring via RS485, CAN and TCP/IP.
