Product Description:
Introducing the advanced and reliable energy flow system from Jinan Deming Power Equipment Co., Ltd. Our bi-directional energy flow technology 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, our system ensures optimal safety and performance.
Featuring a selection of original imported power devices and a fully digital circuit design, our system guarantees superior quality and durability. All the chips used are industrial grade, capable of operating flawlessly in cold, high temperature, and humid environments.
The main circuit of our system utilizes a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring the highest level of safety and reliability. By automatically synchronizing the output with the grid, our system minimizes current harmonic content, resulting in no pollution or impact on the grid.
With closed loop control of grid-connected current, our system allows for convenient and adjustable operation. The wide input voltage range makes it suitable for various occasions. Additionally, our system incorporates a comprehensive power protection scheme and perfect self-test and protection function, ensuring reliable performance at all times.
The compact circuit structure of our system ensures space-saving installation, while the maximum efficiency of ≥ 96% guarantees optimal energy utilization. The protection level can be customized according to the user's needs, providing flexibility and adaptability.
To facilitate communication and monitoring, our system is equipped with an Ethernet interface and supports the standard Modbus TCP communication protocol.
