Our energy system offers bi-directional flow, allowing for both discharge from the battery side to the DC grid and charge from the DC grid side to the battery. It is equipped with fully automatic protection functions for overheating, overload, short circuit, overcurrent, and more, ensuring safety and reliability.
The selection of original imported power devices and fully digital circuit design guarantees the system's efficiency and performance. With industrial-grade chips that can operate in various environments, including cold, high temperature, and humid conditions, our product is built to withstand any challenges.
The main circuit features a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection. This combination ensures synchronized output with the grid, low current harmonic content, and zero pollution or impact on the grid.
Our system also offers closed-loop control of grid-connected current, allowing for easy control and adjustment. With a wide input voltage range, it is suitable for various occasions.
In terms of protection, our system has a comprehensive power protection scheme and perfect self-test and protection functions. In the event of system failure, it will automatically stop working. The circuit structure is compact, and the maximum efficiency is ≥ 96%.
Customization is available for the protection level according to the user's needs. Additionally, we provide an Ethernet interface and support the standard Modbus TCP communication protocol for seamless integration into your existing network.
