Arduino Solar Panel Battery Charge Controller [Project]
posted September 11 2014 10:48.46 by Giorgos Lazaridis

This is a basic battery charger controller designed by Lewis Loflin, which he plans to use with his solar panels. The charging is controlled by a mini Arduino board which in turn controls a P-Mosfet to turn ON or OFF the charging current. Two A/D channels are used to measure the input voltage from the panels and the battery voltage. Also, an ACS712 Hall effect current sensor can optionally be connected to an additional A/D Arduino port to measure the charging current.

A 3-color (or 3 LEDs) are used to indicate the charging status. Red means low or no input, Yellow stands for charging and the Green turns on when the charging is complete.
