Charge controllers guard the battery from over charging from solar panel or over discharging due to the load connected to the system. They range from 5 A to as high as 60 A’s or more.
Charge controllers are categorized into two: series and shunt. They come in digital (mostly above 10 A) or analog form (mostly 5 A).Most of the current charge controllers can detect the system voltage automatically.
They come with different functionalities to suit the customer needs.
