How to operate this solar battery charger circuit.
Battery charging from solar panel circuit.
Upgrading to a relay changeover.
The power produced from a solar panel is usually employed for charging a lead acid battery.
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.
The lead acid battery when completely charged is utilized with an inverter for getting the needed ac mains voltage for running the house electrical.
Max power comes into effect when charging a 12v battery 1 5a.
So thermally it is carefully matched to the current rating.
The circuit uses a 12 volt solar panel and a variable voltage regulator ic lm 317.
Battery voltage 12v solar panel 18v.
Place the solar panel in sunlight.
Preferably the sun rays ought to be incident over the surface of the panel for it to function optimally.
Circuit diagram of solar panel battery charger step 1.
Now set the output voltage by adjusting pot rv1 check the battery voltage using digital multi meter.
The solar panel attaching wires.
For attaching the wire one can make use of the soldered or the un soldered.
The circuit harvests solar energy to charge a 6 volt 4 5 ah rechargeable battery for various applications.
The charger has voltage and current regulation and over voltage cut off facilities.
The solar panel consists of solar cells each rated at 1 2 volts.
The copper stripboard includes copper tracks rows.
