Arduino Solar Panel Charge Controller

As the input voltage from the solar panel rises the charge controller regulates the charge to the batteries preventing any overcharging and disconnect the load when the battery is discharged.

Arduino solar panel charge controller.

1 based on mppt algorithm. It is a device that is placed between the solar panel and the battery bank to control the amount of electric energy produced by sola. And we have about 300 sunny days per year. May 8th 2014 at 17 10 58.

The arduino tries to maximize the watts input from the solar panel by controlling the duty cycle to keep the solar panel operating at its maximum power point.
