Solar Panel Charge Controller Circuit Design

Solar charge controller specifications.

Solar panel charge controller circuit design.

Hello friends today i am back with another project called diy automatic solar charge controller. The second design explains a cheap yet effective less than 1 cheap yet effective solar charger circuit which can be built even by a layman for harnessing efficient solar battery charging. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt. 16w includes power dissipation of d3 typical dropout voltage.

Diy automatic solar charge controller. You will need just a solar panel panel a selector switch and some diodes for getting a reasonably effective solar charger set up. It s a 555 based simple circui. The microcontroller used is in this controller is arduino nano.

7 to 14v adjustable not recommended for 6v applications max power dissipation. The smart charge controller is designed with a view to decrease the battery charging time making it capable of charging more than one battery at a time and getting the desired current from the pv panel. 50w 4a 12v nominal open circuit voltage. The solar charge controller also has board level protection features that protect the board from battery short circuits battery open and battery panel reverse connections.

You can also use other arduino board like pro mini micro and uno. It s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source. 18 to 20v output voltage range.
