Taking About the Working Principle of PWM Solar Charge Controller

       Solar panels produce an electric current through the photoelectric effect of light. Due to the properties andlimitations of materials and light, the generated current is a curve withvolatility. If the generated current is directly charged into the battery ordirectly supplies power to the load, it is easy to cause damage to the batteryand load, which seriously reduces their service life. Therefore, we must firstsend the current into the pwm solar charge controller, using a series of special chipcircuits to digitally adjust it, using three-stage charging, to ensure the safeoperation of the battery life. When supplying power to the load, the current ofthe battery is also let to flow into the solar controller first, after itsadjustment, and then the current into the load. The purpose of this:

       1,It stabilizes the discharge current

       2, It ensures the battery which is notdischarged

       3,It monitors and protects load and battery
