One 555 timer ic is used for detecting the voltage level and relay is used to disconnect the ac input. 5 transistorized solar charger controller circuit. Home mini projects simple solar garden light circuit with automatic cut off.
The fifth idea presented below details a simple solar charger circuit with automatic cut off using transistors only.
One 555 timer ic is used for detecting the voltage level and relay is used to disconnect the ac input. When the battery gets fully charged the solar panel keeps running and this can result in battery getting deep discharged which will shorten its life. Solar battery charger operated on the principle that the charge control circuit will produce the constant voltage. 7808 voltage regulator is used for constant supply to the operation of the circuit to cut at a required fixed voltage.
