Introducing the innovative bi-directional energy flow system by Jinan Deming Power Equipment Co., Ltd. This cutting-edge technology allows for seamless discharge and charge of energy between the battery and the DC grid. With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent safeguards, our system ensures optimal safety at all times.
Our product boasts a selection of original imported power devices and features a fully digital circuit design. All chips used are of industrial grade, guaranteeing reliable performance even in extreme conditions such as cold, high temperature, and humidity.
The main circuit of our system incorporates the DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination ensures the utmost safety and reliability of the system. Furthermore, the output is automatically synchronized with the grid, resulting in low current harmonic content and zero pollution or impact on the grid.
With closed loop control of grid connected current, our system offers controllable and adjustable functionality. It also boasts a wide input voltage range, making it suitable for various occasions. Our system features an all-round power protection scheme and a self-test and protection function that guarantees the system will stop working in case of any failure.
The compact circuit structure of our product ensures maximum efficiency of at least 96%. Additionally, the protection level can be customized according to the user's needs. For enhanced connectivity, our system provides an Ethernet interface and follows the standard Modbus TCP communication protocol.
Experience the future of energy management with Jinan Deming Power Equipment Co., Ltd's bi-directional energy flow system. Harness the power of technology to optimize energy usage and protect the environment.
