Energy flows bi-directionally, allowing for discharge from the battery side to the DC grid or charging from the DC grid side to the battery. The system features fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more. The selection of original imported power devices ensures high quality.
The fully digital circuit design, combined with industrial-grade chips that can operate normally in various environments, guarantees reliable performance even in cold, high temperature, and humid conditions. The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, ensuring safety and reliability.
The output of the system is automatically synchronized 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 precise and adjustable operation. With a wide input voltage range, the system is suitable for different occasions.
The system also includes an all-round power protection scheme and perfect self-test and protection function. In case of system failure, it will automatically stop working. The compact circuit structure ensures maximum efficiency of at least 96%. The protection level can be customized according to the user's needs.
Additionally, the product provides an Ethernet interface, supporting standard Modbus TCP communication protocol for seamless integration into existing systems.
