Energy Storage Microgrid Bidirectional DC DC Converter

Product Description

Product Description:
The energy flow of our product is bi-directional, allowing it to discharge from the battery side to the DC grid or charge from the DC grid side to the battery. With fully automatic protection functions for overheating, overload, short circuit, and overcurrent, our product ensures safety and reliability.
Our selection of original imported power devices, along with a fully digital circuit design and industrial-grade chips, ensures the product can operate normally in cold, high temperature, and humid environments. The main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, further enhancing its safety and reliability.
Our product automatically synchronizes its output 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. Additionally, the wide input voltage range makes it suitable for different occasions.
Equipped with a comprehensive power protection scheme and perfect self-test and protection function, our product ensures all-round protection. In case of system failure, it will stop working to prevent further damage. The compact circuit structure ensures maximum efficiency of at least 96%.
The protection level of our product can be customized according to the user's needs. It also provides an Ethernet interface and follows the standard Modbus TCP communication protocol for easy connectivity.
