This paper introduces a solar controller based on SCM, system uses STC15F2K61S2 microcontroller as the core device of the control circuit. This design uses PWM (pulse width modulation) control technology and MOSFET tube is opened and closed to control the battery charging and discharging. The experimental results show that, the controller performance is reliable, can monitor the state of implementation of solar battery and storage battery, battery charge and discharge control optimal, to prolong the service life of the battery to.
