Solar panel 12v battery charger circuit diagram.

Circuit diagram of solar panel battery charger step 6 from below you can see the soldered connections how they run along the copper tracks. 1n4007 diodes 3nos. 7808 voltage regulator is used for constant supply to the operation of the circuit to cut at a required fixed voltage. Solar panel 20v 1 amp.

One 555 timer ic is used for detecting the voltage level and relay is used to disconnect the ac input. 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. Ic 7812 1no. That looks cool isn t it.

The following solar panel wiring diagram shows that a 12v 120w pv panel is connected to the solar charge controller panel negative terminal of panel to the negative terminal of mppt charge controller and vice versa for positive terminal. Before delving into the following concepts you can probably try this super easy solar battery charger which will ensure safe and guaranteed charging of a small 12v 7 ah battery through a small solar panel. The circuit is using an lm317t voltage regulator ic.
