Product Description:
Introducing our latest innovation from Jinan Deming Power Equipment Co., Ltd, the state-of-the-art bi-directional energy flow system. This cutting-edge technology allows for effortless energy discharge from the battery side to the DC grid or seamless charging from the DC grid side to the battery.
Our system is equipped with fully automatic protection functions, ensuring your safety and peace of mind. It effectively safeguards against overheating, overload, short circuit, overcurrent, and more. We use only top-quality original imported power devices and employ a fully digital circuit design for optimal performance.
Rest assured that all our chips are industrial grade, capable of operating flawlessly in cold, high temperature, and humid environments. With the main circuit incorporating a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, you can trust in the system's safety and reliability.
Our system's output is automatically synchronized with the grid, ensuring low current harmonic content and no pollution or impact on the grid. It also features closed-loop control of grid-connected current, providing controllability and adjustability. The wide input voltage range makes it suitable for various occasions.
Designed with all-round power protection and a perfect self-test and protection function, our system guarantees your peace of mind. In the event of a system failure, it will automatically stop working, preventing any further issues.
The circuit structure is compact, allowing for easy installation, and boasts a maximum efficiency of at least 96%. Additionally, the protection level can be customized to meet your specific needs. For seamless integration into your network, our system provides an Ethernet interface and follows the standard Modbus TCP communication protocol.
Experience the future of energy management with our bi-directional energy flow system from Jinan Deming Power Equipment Co., Ltd.
