MPPT Solar Charge Controller

a mppt solar charge controller is the charge controller embedded with mppt algorithm to maximize the amount of current going into the battery from pv module.
mppt is dc to dc converter which operates by taking dc input from pv module, changing it to ac and converting it back to a different dc voltage and current to exactly match the pv module to the battery. Examples of dc to dc converter are..

• boost converter is power converter which dc input voltage is less than dc output voltage. That means pv input voltage is less than the battery voltage in system.

• buck converter is power converter which dc input voltage is greater than dc output voltage. That means pv input voltage is greater than the battery voltage in system.
