Performance characteristics
（1）The 32-bit DSP (Digital Processor TI 2812) +ARM (Touch Screen Master Chip) platform is used for touch screen display and operation, which facilitates field operation and parameter setup. The core driver of DSP control and ARM realize peripheral functions such as display and communication to improve power reliability.
（2）Support RS485, WiFi, GPRS, Ethernet communication, satisfy customer remote monitoring and other functions; can display AC and DC side voltage, current, operation mode, operation status, fault information, and can upload related data to the Internet of Things platform through the communication interface, and can start and stop power supply, parameter settings and other operations through the computer or mobile phone;
（3）Adopt three-phase four-bridge arm structure, which can carry 100% unbalanced load;；
（4）Designed for smart grids and smart microgrids, accept grid dispatching, cut peaks and fill valleys；
（5）Meets the access of lead-acid accumulator, lithium power, super capacitor, vanadium battery and other different energy storage forms, and has a wide range of applications.
