Product Description:
Introducing the innovative and reliable bi-directional energy flow system from Jinan Deming Power Equipment Co., Ltd. This cutting-edge technology allows for seamless energy discharge from the battery side to the DC grid or efficient charging from the DC grid side to the battery. With its fully automatic protection functions, including overheating, overload, short circuit, and overcurrent protection, you can trust that your power system is always safeguarded.
Our system is equipped with original imported power devices and features a fully digital circuit design. The industrial-grade chips ensure optimal performance even in extreme conditions such as cold, high temperature, and humid environments. The main circuit incorporates the renowned DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, offering unparalleled safety and reliability.
With automatic synchronization to the grid and low current harmonic content, our system ensures minimal pollution and impact on the grid. The closed-loop control of grid-connected current allows for precise and adjustable power management. Additionally, the wide input voltage range makes it suitable for various occasions, providing flexibility and adaptability.
Rest assured, our system boasts a comprehensive power protection scheme and a self-test and protection function, ensuring continuous, uninterrupted operation. Should any system failure occur, the system will promptly stop working, minimizing potential risks.
Designed with a compact circuit structure, our system achieves a maximum efficiency of ≥ 96%. Furthermore, the customizable protection level caters to your specific needs, offering tailored solutions for your power requirements.
For seamless integration and easy communication, our system provides an Ethernet interface and follows the standard Modbus TCP communication protocol. Stay connected and in control with our advanced power solution.
