Battery Charging From Solar Panel Circuit

Battery voltage 12v solar panel 18v.

Battery charging from solar panel circuit.

In our 4rth automatic solar light circuit we incorporate a single relay as a switch for charging a battery during day time or as long as the solar panel is generating electricity and for illuminating a connected led while the panel is not active. Preferably the sun rays ought to be incident over the surface of the panel for it to function optimally. The circuit harvests solar energy to charge a 6 volt 4 5 ah rechargeable battery for various applications. The lead acid battery when completely charged is utilized with an inverter for getting the needed ac mains voltage for running the house electrical.

Give the connections according to the circuit diagram. The charger has voltage and current regulation and over voltage cut off facilities. Upgrading to a relay changeover. Each every track is electrically.

Circuit diagram of solar panel battery charger step 1. The copper stripboard includes copper tracks rows. Place the solar panel in sunlight. P 18v 12v 1 5a 9w.

The circuit uses a 12 volt solar panel and a variable voltage regulator ic lm 317. The solar panel attaching wires. Max power comes into effect when charging a 12v battery 1 5a. So thermally it is carefully matched to the current rating.

The solar panel consists of solar cells each rated at 1 2 volts. For attaching the wire one can make use of the soldered or the un soldered.
