Welcome to Jinan Deming Power Equipment Co., Ltd. We are pleased to introduce our latest product:
Our product allows for energy to discharge from the battery side to the DC grid or charge from the DC grid side to the battery. This bi-directional flow ensures efficient energy management.
Our product features fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more. This guarantees the safety and longevity of the equipment.
We have carefully selected original imported power devices and used industrial-grade chips that can operate reliably in various environmental conditions, including cold, high temperature, and humid environments.
With a fully digital circuit design, our product utilizes a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This ensures a safe and reliable performance.
The output of our product automatically synchronizes with the grid, resulting in low current harmonic content. This eliminates pollution and minimizes any impact on the grid.
The grid-connected current is controllable and adjustable through closed-loop control. Additionally, our product offers a wide input voltage range, making it suitable for various applications.
Our system provides all-round power protection and features a perfect self-test and protection function. In case of any system failure, it will automatically stop working. With a compact circuit structure, the maximum efficiency of our product is ≥ 96%.
We offer customizable protection levels to meet the specific needs of our customers. Additionally, our product provides an Ethernet interface and supports the standard Modbus TCP communication protocol.
Jinan Deming Power Equipment Co., Ltd is a leading manufacturer of power equipment. We strive to deliver high-quality products that meet the needs of our customers.
