Solar Panel Battery Charger Circuit Diagram

If a 20w solar panel has an output current of 2 5a in full sunlight the charge current will be 2 5a.

Solar panel battery charger circuit diagram.

The output current is identical to the solar panel output current. Connect the ve wire from the solar panel to the ve of the circuit then connect the battery s ve to the circuit. Solar panel output voltage is directly fed into lm317 positive regulator circuit and it is adjusted to give 12 volt output and battery connected to this bias through 3a 50v schottky diode. The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode.

Check the battery voltage using digital multi meter. Place the solar panel in sunlight. The cd4047 ic is connected and configured as astable multivibrator when we turn on spst switch this circuit starts oscillation. The circuit uses a 12 volt solar panel and a variable voltage regulator ic lm 317.

The charger has voltage and current regulation and over voltage cut off facilities. I have added in the brown wire as brown line the diode as a blue line i have also added in the ve ve makers for the battery. The fig show the wiring diagram of the ssc. As can be seen in the given circuit diagram the design basically consists of a solar panel a pnp transistor few leds a battery and a few resistors.

The circuit design is extremely straightforward and may be understood with the following points. Circuit is simple and inexpensive. Now set the output voltage by adjusting pot rv1. Regarding the battery ah capacity it is generally best if the battery can be fully charged within one day or less.

Using a current control feature the specialty of the design is that it incorporates a current control feature also.
