Product Description

Jinan Deming Power Equipment Co., Ltd

Introducing our latest innovation in power equipment - a highly efficient and reliable solution for bi-directional energy flow. Our product offers a seamless discharge from the battery side to the DC grid or a charge from the DC grid side to the battery, providing flexibility and convenience.

With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, our power equipment ensures a safe and worry-free operation. We have carefully selected original imported power devices, guaranteeing superior quality and performance.

Our fully digital circuit design, combined with industrial-grade chips that can operate flawlessly in various environmental conditions, ensures a stable and efficient operation. The main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring safety and reliability.

Our product's output is automatically synchronized 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 easy controllability and adjustability.

With a wide input voltage range, our power equipment is suitable for various occasions. It also includes a comprehensive power protection scheme and a perfect self-test and protection function. In case of any system failure, it will automatically stop working.

The compact circuit structure ensures efficient space utilization, and the maximum efficiency of our product is ≥ 96%. Additionally, the protection level can be customized according to the user's needs, providing a tailored solution.

To facilitate communication and integration, our power equipment provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
