Abstract The article provides a medium and small power photovoltaic control system based on MCU. The system perfects the management and protection for the charge and discharge of storage battery also for the load and solar power supply. The system adopts the LCD, keyboard and asynchronous serial communication to enhance the system supervision and remote management and convenience to maintain and scrutinize one unit or several systems. This system has already been made use of in several photovoltaic product series and obtains the satisfied result.
Keywords：MCU, solar energy, Photovoltaic System, asynchronous serial communication
