Description: This paper introduces a solar controller based on MCU, AT89S51 chip with low power consumption, high performance of the system as the core device control circuit. This system consists of solar battery module, battery, charging and discharging circuit, voltage acquisition circuit, SCM control circuit and optocoupler drive circuit. Design using PWM (pulse width modulation) control technology to control the battery charge and discharge, by controlling the MOSFET tube open and closed to control the battery charge and discharge of the objective. The experimental results show that, the controller performance is reliable, can monitor the solar cell and battery state of charge and discharge the battery, to achieve optimal control, to prolong the service life of the battery.
