Introducing the bi-directional energy flow system by 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 maximum flexibility and efficiency.
Our system is equipped with fully automatic protection functions, including overheating, overload, short circuit, and overcurrent protection. With the selection of original imported power devices and a fully digital circuit design, our product guarantees superior performance and reliability.
All the chips used in our system are industrial grade, ensuring normal operation even in cold, high-temperature, and humid environments. The main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, offering a safe and trustworthy solution.
With automatic synchronization with the grid, our system ensures low current harmonic content, resulting in no pollution or impact on the grid. The closed-loop control of grid-connected current allows for precise and adjustable output.
Our system boasts a wide input voltage range, making it suitable for various occasions. Additionally, it is equipped with an all-round power protection scheme and perfect self-test and protection functions. In the event of a system failure, it will automatically stop working.
The compact circuit structure ensures maximum efficiency, with a rating of ≥ 96%. Furthermore, the protection level of our system can be customized according to the user's needs, providing tailored solutions for every requirement.
For seamless integration and communication, our system provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
Experience the future of energy management with our bi-directional energy flow system. Trust Jinan Deming Power Equipment Co., Ltd for reliable, efficient, and sustainable solutions.
