Description:
PV grid-connected power system includes PV modules, grid-connected inverter, meter and power switch board.
The PV modules convert the solar energy to the DC power, then the grid-connected inverter the DC power to the sine wave AC power which has the same frequency and phase with the grid voltage.
The AC power feed in the grid partly and the other powers supply the local loads.
Features:
1. Improve the system efficiency higher
2. High conversion efficiency
3. Advanced technology for maximum power point tracking(MPPT)(>97%)MPPT efficiency
4. Wide input voltage range
5. High reliability due to compltte protection function
6. Powerful communication interfaces
7. Easy operation and installation
8. Easy-to-set multilingual LCD display
9. Adjustable protection / operation parameters
