3.Product feature and application of PWM solar charge controller circuit
CD12/24-30 will connect the solar panel and battery, transfer the PV power to be battery power.
This design uses low power consumption, high performance, super interference STC89C52 microcontroller as the core device to control the whole circuit. The system hardware circuit is composed of solar battery charging and discharging circuit, voltage acquisition and display circuit, single chip microcomputer control circuit and RS232 serial communication circuit, which mainly realizes the collection and display of the battery voltage. The software part is based on the PWM (Pulse Width Modulation) pulse width modulation control strategy. The program makes the MCU output PWM control signal. By controlling the optocoupler to switch off and control the opening and closing of the MOSFET tube, the battery charging and discharging is controlled. At the same time, the battery overcharge and overcharge are realized according to the power requirement. Protection and short circuit protection. The experiment shows that the controller has excellent performance and high reliability. It can monitor the state of solar panels and batteries at all times, realize the optimal charge and discharge control of the battery and prolong the service life of the battery.
