Solar Panel Battery Charger Circuit

The solar panel attaching wires.

Solar panel battery charger circuit.

For attaching the wire one can make use of the soldered or the un soldered. Online shopping from a great selection at health household store. The circuit uses a 12 volt solar panel and a variable voltage regulator ic lm 317. Using a current control feature the specialty of the design is that it incorporates a current control feature also.

The circuit diagram shows a simple set up using the ic lm 338 which has been configured in its standard regulated power supply mode. By adjusting its adjust pin output voltage and current can be regulated. The circuit of a simple lm338 solar battery charger is shown below using the ic lm338. A 5v step up voltage booster is also connected to the battery and is used to convert from 3 7v dc to 5v dc.

12 volt dc is available from the panel to charge the battery. Solar cells are connected to the input of the lithium battery charger tp4056 whose output is connected to the 18560 lithium battery. Now set the output voltage by adjusting pot rv1 check the battery voltage using digital multi meter. Circuit diagram of solar panel battery charger step 1.

The solar panel consists of solar cells each rated at 1 2 volts. Give the connections according to the circuit diagram. Voltage booster s input ranges from 0 9 to 5 0v. To keep the junction temperature below the 125 c max the power must be limited to about 10w.

How to operate this solar battery charger circuit. Each every track is electrically. The copper stripboard includes copper tracks rows. 12v solar battery charger controller circuit make download circuit diagram a.

If a smaller or less effective heat sink is used the maximum power dissipation must be de rated. Charging voltage is typically around 4 2v. Place the solar panel in sunlight.
