In order to sense the solar panel voltage a voltage divider was used to step it down, as it can be greater than the maximum voltage of 5V that the Arduino can handle and thus it can damage the board.

This is a complete re-write of the original AngeloCasi/FUGU-ARDUINO-MPPT-FIRMWARE. It is compatible with the original hardware design you can find on Instructables. The charger uses a simple CC-CV ...

Abstract: The present paper aims to propose an implement of perturb and observe (P&O) technique for photovoltaic systems using a boost converter driven by Arduino MEGA 2560 in a view of providing an ...
