Introducing the bi-directional energy flow system from Jinan Deming Power Equipment Co., Ltd. This cutting-edge device allows for the seamless discharge of energy from the battery to the DC grid, or the convenient charging from the DC grid to the battery. With fully automatic protection functions for overheating, overload, short circuit, and overcurrent, you can trust in the safety and reliability of our product.
Our system features a selection of original imported power devices and a fully digital circuit design. All the chips used are industrial grade and can operate normally in cold, high temperature, and humid environments. The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring optimal performance.
With automatic synchronization to the grid, our system boasts low current harmonic content, resulting in no pollution or impact on the grid. The grid connected current is precisely controlled and adjustable through closed loop control, providing you with flexibility. The wide input voltage range makes our system suitable for various occasions.
Our product also offers all-round power protection and a perfect self-test and protection function. In the event of a system failure, it will automatically stop working, ensuring safety. The compact circuit structure ensures efficiency, with a maximum efficiency of ≥ 96%. Additionally, the protection level can be customized according to your specific needs.
To enhance connectivity, our system provides an Ethernet interface and supports the standard Modbus TCP communication protocol. Stay connected and in control with ease.
Invest in the future of energy management with Jinan Deming Power Equipment Co., Ltd. Experience the benefits of our advanced bi-directional energy flow system today!
