Solar Panel Charge Controller Circuit Design

It s an automatic switching circuit that used to control the charging of a battery from solar panels or any other source.

Solar panel charge controller circuit design.

The microcontroller used is in this controller is arduino nano. Mppt solar charge controller block diagram please contact innovatech switching power india to purchase samples of this reference design board. Nowadays the most advance solar charge controller available in the market is maximum power point tracking mppt. Hello friends today i am back with another project called diy automatic solar charge controller.

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. This design is suitable for a 50w solar panel to charge a commonly used 12v lead acid battery. 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. Central solar battery charging station csbcs provides power to trickle charging of batteries from stand alone solar panels.

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. Solar charge controller specifications. 16w includes power dissipation of d3 typical dropout voltage.

You can also use other arduino board like pro mini micro and uno. 18 to 20v output voltage range. 50w 4a 12v nominal open circuit voltage.
