Product Description

Introducing the revolutionary energy solution from Jinan Deming Power Equipment Co., Ltd. Our cutting-edge technology allows for bi-directional energy flow, enabling efficient discharge from the battery side to the DC grid or charge from the DC grid side to the battery.

With fully automatic protection functions against overheating, overload, short circuit, overcurrent, and more, our product ensures the utmost safety and reliability. We have carefully selected original imported power devices and implemented a fully digital circuit design for optimal performance.

Our industrial-grade chips are designed to operate flawlessly 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, guaranteeing a secure and reliable operation.

Not only does our product deliver an automatically synchronized output with the grid, but it also boasts low current harmonic content, ensuring no pollution or impact on the grid. The closed-loop control of grid-connected current offers controllable and adjustable functionality.

With a wide input voltage range, our system is suitable for various occasions. It incorporates an all-round power protection scheme and a perfect self-test and protection function. In the event of a system failure, it will promptly stop working.

Our circuit structure is compact, maximizing efficiency with a minimum of 96%. Additionally, the protection level can be customized according to your specific needs. For seamless integration into your network, we provide an Ethernet interface and support the standard Modbus TCP communication protocol.

Choose Jinan Deming Power Equipment Co., Ltd for an energy solution that meets the highest standards of performance, safety, and reliability. Experience the future of energy technology today.
