Solar System Controller MPPT-12V20A

1. Breif Introduction The most important feature of this controller is intelligently tracking input voltage from solar panel, which could let solar panel always work at Maximum Power Point of V-A curve. Compared with normal solar charge controller, MPPT controller could increase efficiency at 10%-30%. 2. Function: This MPPT controller not only has above mentioned special function, but also equipped with completely protecting and controlling functions:1) Over-charge protection2) Over-discharge protection3) Battery reverse current protection 4) Over-load protection5) Short-circuit protection6) Reverse Polarity Connection Protection 3.
