Feature: The most important feature of this controller is intelligent tracking input voltage from solar panel, which could let solar panel always working at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller could increase 10%-30% electrical power using efficiency from solar panel. Function: This MPPT controller is not only have above mentioned special function, at the same time including completely Protecting and Controlling functions: Overcharge protection Overdischarge protection Battery Reverse Current Protection Overloading Protection Short Circuit Protection Reverse Polarity Connection Protection Form a complete set: Solar Panel: 12V solar system should use 40pcs cells laminated solar panel. The maximum power point voltage is18V above. 24V solar system should use 2pcs above mentioned solar panels. 48V solar system should use 4pcs above mentioned solar panels.
