MT2075 is a sort of 20amp MPPT Solar charge Controller.
It is fit for 12V/24V automatic recognition as well as 20A charge and discharge current.
A solar charge controller controls the power from PV go to the battery. It protects deep cycle batteries from overcharged during the day, and prohibits the power run back to the PV at night and drain the batteries. Some charge controllers add some additional functions, like lighting and load control, but its primary job is protecting batteries.
There are two different technologies for a solar charge controller-PWM and MPPT. How they work and perform in a system is very different from each other. An MPPT charge controller is more expensive than a PWM charge controller, but it is often worth it to pay the extra money.
