Product Description:
1. Energy flows bi-directionally, i.e. it can discharge from the battery side to the DC grid or charge from the DC grid side to the battery.
2. Fully automatic protection functions for overheating, overload, short circuit, overcurrent, etc.
3.Selection of original imported power devices
4.Fully digital circuit design
5.All the chips are industrial grade and can operate normally in cold, high temperature and humid environment.
6.The main circuit adopts DSP chip produced by TI of America, Infineon IGBT module and Infineon movement for driving and protection, which is safe and reliable;
7.The output is automatically synchronized with the grid, the current harmonic content is low, and there is no pollution and impact on the grid;
8. Closed loop control of grid connected current, controllable and adjustable.
9.Wide input voltage range, suitable for different occasions
10.The system has all-round power protection scheme and perfect self-test and protection function. In case of system failure, it will stop working;
11.The circuit structure is compact and the maximum efficiency ≥ 96%;
12. Protection level can be customized according to the user's needs;;
13.Provide Ethernet interface, standard Modbus TCP communication protocol.
