Features:
<br />Always keep the battery on fill voltage condition.
<br />Prevent the battery from over-charging & over-discharging. 
<br />Prevent the battery from reverse charging to solar panels during nights.
<br />Reverse Polarity Protection for Battery and Solar Panels.
<br />This MPPT controller has perfect SOC function, control charge current, and supply power to the loads.
<br />The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.
