Using a current control feature the specialty of the design is that it incorporates a current control feature also.
Solar panel charger circuit.
It s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source.
For attaching the wire one can make use of the soldered or the un soldered.
The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode.
The circuit harvests solar energy to charge a 6 volt 4 5 ah rechargeable battery for various applications.
The solar panel attaching wires.
Now simply use any power cable and connect it to the usb pin of the module and the other end to your mobile phone.
A solar cell radio used a 3v or two 1 2v nickel cadmium battery or nickel metal hydride battery in it.
Circuit diagram of cell phone solar charger is given below.
It s a 555 based simple circuits the charge the battery when the battery charge goes below the lower limits and stop charging when the battery reaches it s upper limit voltage.
The charger has voltage and current regulation and over voltage cut off facilities.
How to operate this solar battery charger circuit.
Give the connections according to the circuit diagram.
The circuit of a simple lm338 solar battery charger is shown below using the ic lm338.
The transistor is the only active component which is positioned as a switch for preventing the battery voltage from reaching the connected leds during day time.
Circuit diagram of solar panel battery charger step 1.
Solar panels here is a solar charger circuit that is used to charge lead acid or ni cd batteries using the solar energy power.
As shown in the above wiring diagram simply solder the solar panel in parallel and connect them to a boost converter module through a switch.
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 battery can not be removed.
