Product Description
- 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.
- Fully automatic protection functions for overheating, overload, short circuit, overcurrent, etc.
- Selection of original imported power devices.
- Fully digital circuit design.
- All the chips are industrial grade and can operate normally in cold, high temperature and humid environment.
- 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.
- The output is automatically synchronized with the grid, the current harmonic content is low, and there is no pollution and impact on the grid.
- Closed loop control of grid connected current, controllable and adjustable.
- Wide input voltage range, suitable for different occasions.
- The system has all-round power protection scheme and perfect self-test and protection function. In case of system failure, it will stop working.
- The circuit structure is compact and the maximum efficiency ≥ 96%.
- Protection level can be customized according to the user's needs.
- Provide Ethernet interface, standard Modbus TCP communication protocol.
