Product Description

Jinan Deming Power Equipment Co., Ltd - Product Description

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


• Features fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more.


• Equipped with original imported power devices for enhanced performance.


• Utilizes a fully digital circuit design for efficient operation.


• All chips used are industrial grade and can operate normally in cold, high temperature, and humid environments.


• Main circuit incorporates 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.


• Enables closed loop control of grid connected current, allowing for easy controllability and adjustability.


• Offers a wide input voltage range, making it suitable for various occasions.


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


• Compact circuit structure with a maximum efficiency of ≥ 96%.


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


• Includes an Ethernet interface and supports the standard Modbus TCP communication protocol.
