Welcome to Jinan Deming Power Equipment Co., Ltd. We are proud to introduce our latest product:
Our Bi-Directional Energy Flow System allows for efficient energy transfer between the battery and the DC grid. Whether you need to discharge energy from the battery side to the DC grid or charge energy from the DC grid side to the battery, our system has got you covered.
With fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more, you can trust that your energy flow is always safe and secure.
We have selected original imported power devices and implemented a fully digital circuit design. All the chips used are industrial grade, ensuring normal operation even in cold, high temperature, and humid environments.
The main circuit of our system features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination guarantees the utmost safety and reliability.
Our system's output is automatically synchronized with the grid, resulting in low current harmonic content. This means no pollution or impact on the grid, making it an environmentally friendly choice.
With closed-loop control of grid connected current, our system offers controllable and adjustable output. The wide input voltage range makes it suitable for various occasions.
In terms of protection, our system has an all-round power protection scheme and perfect self-test and protection function. In the event of a system failure, it will automatically stop working, ensuring your safety.
The compact circuit structure of our system ensures maximum efficiency, with a rating of ≥ 96%. Additionally, the protection level can be customized according to your specific needs.
To make communication seamless, we provide an Ethernet interface with standard Modbus TCP communication protocol.
Choose the Bi-Directional Energy Flow System from Jinan Deming Power Equipment Co., Ltd for a reliable and efficient energy solution.
