Introducing our latest innovation in power equipment - the bi-directional energy flow system. This cutting-edge technology allows energy to 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, ensuring safety and reliability in every operation. It features overheating, overload, short circuit, and overcurrent protection, among others. Additionally, we have carefully selected original imported power devices for optimal performance.
With a fully digital circuit design, our system guarantees seamless operation and compatibility with various environments. All the chips used are industrial grade, capable of functioning flawlessly in cold, high temperature, and humid conditions.
The main circuit incorporates 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 utmost safety and reliability.
Our system boasts an automatically synchronized output 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 control and adjustment.
With a wide input voltage range, our system is suitable for various occasions and applications. It features a comprehensive power protection scheme and a self-test and protection function that guarantees uninterrupted operation. In case of system failure, it will automatically stop working.
The compact circuit structure ensures space efficiency, and the maximum efficiency of our system is an impressive ≥ 96%. Furthermore, the protection level can be customized according to the user's needs, providing tailored solutions.
For seamless integration and communication, our system provides an Ethernet interface and follows the standard Modbus TCP communication protocol.
