Introducing the advanced and reliable power equipment from Jinan Deming Power Equipment Co., Ltd. Our bi-directional energy flow system allows for seamless discharge from the battery side to the DC grid or charging from the DC grid side to the battery. With fully automatic protection functions, including overheating, overload, short circuit, and overcurrent, you can trust in the safety and efficiency of our product.
Our power devices are carefully selected from original imported sources, ensuring top-notch quality. The fully digital circuit design, along with industrial-grade chips that can operate in extreme conditions, guarantees optimal performance even in cold, high temperature, and humid environments.
The main circuit of our system features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination ensures the utmost safety and reliability. Additionally, our system offers automatic synchronization with the grid, low current harmonic content, and no pollution or impact on the grid.
With closed-loop control of grid-connected current, our system provides controllable and adjustable output. The wide input voltage range makes it suitable for various occasions. Our product also boasts a comprehensive power protection scheme, perfect self-test, and protection functions. In the event of a system failure, it will automatically stop working.
The compact circuit structure of our power equipment ensures maximum efficiency of at least 96%. Furthermore, the protection level can be customized according to your specific needs. To facilitate communication and integration, we provide an Ethernet interface and support the standard Modbus TCP communication protocol.
Choose Jinan Deming Power Equipment Co., Ltd for a reliable, efficient, and versatile power solution. Experience the benefits of our advanced technology and superior performance.
