Introducing the advanced bi-directional energy flow system from Jinan Deming Power Equipment Co., Ltd. This cutting-edge technology allows for seamless discharge from the battery side to the DC grid or charge from the DC grid side to the battery, providing efficient energy management.
Our system is equipped with fully automatic protection functions, including overheating, overload, short circuit, and overcurrent protection, ensuring the safety and reliability of your energy flow.
With a selection of original imported power devices and a fully digital circuit design, our system guarantees high performance and durability. All the chips used are industrial grade, capable of operating normally in extreme environments such as cold, high temperature, and humidity.
The main circuit of our system features top-of-the-line components including a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination ensures the system's safety and reliability.
Our system's output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid. The closed-loop control of grid-connected current allows for precise and adjustable power management.
With a wide input voltage range, our system is suitable for various occasions, providing flexible energy solutions. Additionally, the system is equipped with a comprehensive power protection scheme and perfect self-test and protection functions, ensuring uninterrupted operation.
The compact circuit structure of our system allows for maximum efficiency, with a rating of ≥ 96%. The protection level can be customized according to your specific needs, providing tailored solutions for your energy management requirements.
For seamless connectivity and control, our system provides an Ethernet interface and supports the standard Modbus TCP communication protocol, allowing for easy integration into your existing network.
