Introducing the latest innovation from Jinan Deming Power Equipment Co., Ltd - the bi-directional energy flow system. This cutting-edge technology allows for energy to be discharged from the battery side to the DC grid or charged from the DC grid side to the battery. With its fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, you can trust that your system is safe and secure.
Our system features original imported power devices and a fully digital circuit design. All the chips used are industrial grade, ensuring they can operate normally in cold, high temperature, and humid environments. The main circuit is equipped with a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, providing a safe and reliable solution.
Not only does our system offer superior performance, but it also prioritizes grid compatibility. The output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid. With closed-loop control of grid-connected current, the system is controllable and adjustable for your specific needs.
Our system is designed to be versatile, with a wide input voltage range suitable for different occasions. It also boasts a comprehensive power protection scheme and perfect self-test and protection functions. In the event of a system failure, it will automatically stop working, ensuring the safety of your equipment.
Compact in size, our system offers maximum efficiency of ≥ 96%. Additionally, the protection level can be customized according to your specific requirements. To facilitate communication and monitoring, we provide an Ethernet interface and support the standard Modbus TCP communication protocol.
Choose the bi-directional energy flow system from Jinan Deming Power Equipment Co., Ltd for a reliable, efficient, and flexible solution to meet your power needs.
