Product Description

Jinan Deming Power Equipment Co., Ltd - Product Description

• Energy flows bi-directionally, allowing discharge from the battery side to the DC grid or charge from the DC grid side to the battery.


• Fully automatic protection functions for overheating, overload, short circuit, overcurrent, etc.


• Selection of original imported power devices for reliable performance.


• Fully digital circuit design for enhanced efficiency.


• All chips are industrial grade, ensuring normal operation in cold, high temperature, and humid environments.


• Main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring safety and reliability.


• Output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.


• Closed loop control of grid connected current allows for controllable and adjustable output.


• Wide input voltage range makes it suitable for different occasions.


• The system has a comprehensive power protection scheme and perfect self-test and protection function. In case of system failure, it will stop working.


• Circuit structure is compact, and the maximum efficiency is ≥ 96%.


• Protection level can be customized according to the user's needs.


• Provides Ethernet interface and standard Modbus TCP communication protocol.
