Design of the Solar Photovoltaic System Data Acquisition Board

This article describes the principle and characteristics of solar photovoltaic systems, it selects the micro-controller as photovoltaic generating system controller, and design both the outer core circuit and software of the data processing. Here uses RS232 combined with the LED screen to show the system operation state. Though series of experimental, the results show that the data acquisition board structure is simple and the system perform stable.
