Solar Panel Charging Circuit DC-DC Voltage Regulator

It is a circuit where you can charge your rechargeable batteries with the energy coming from solar panels. You can also use this circuit as a voltage regulator. Two 7-segment displays on the product allow you to see input and output voltages, output amperes and powers.

You can adjust the output voltage and constant current with the help of potentiometers on the product. You can see the functions of the buttons and pots on the product in the image below.
