Arduino powered Solar Battery Charger

The following design is for a Solar battery charger ran by an Arduino Nano. It can handle a standard lead acid 12V battery, like for a scooter or a car. Furthermore the design has been tested and runs with 90% efficiency under 70ᵒC (158ᵒF). It can take up to 20V on the input site of the charger. Also in order to improve the efficiency a MPPT tracker is implemented in the code to ensure that the maximum powe ...
