Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
The solar panel supplies the peak voltage of 6 V, at 500 ma during daytime, which charges the battery as long as this voltage is available from the solar panel. The resistor Rx keeps the charging current to a safe lower level so that even after the battery is fully charged, the minimal current does not harm the battery.
So, let’s dive into the world of renewable energy and learn how to create a solar battery charger! To build the solar battery charger, you must first connect the LM317 voltage regulator IC and the BC547 transistor with the help of resistors and capacitors. Then, connect the LED indicators and the voltage comparators using the LM324 quad op-amp.
The above 48V solar battery charger circuit with high, low cut-off may be modified with these specifications by introducing a window comparator stage, as shown at the extreme left of the circuit below. Here the opamps are replaced by three op amps from the IC LM324. The window comparator is made by two of the 4 opamps inside the LM324.
To maintain your solar battery charger, you should regularly clean the solar panel to ensure maximum efficiency and store the charger in a dry and cool place when not in use. You can also use a battery tester to check the battery’s performance.
In the 6V solar battery charger circuit, the LM317 is set up to generate a fixed 7V output using the resistances 120 ohms and 560 ohms. The voltage comparators in the LM324 quad op-amp are used to compare the voltage levels during the charging or discharging process of the battery.
