MPPT SOLAR Charge Controller 45Amp 12V/24V/36V/48VDC Auto Charger MPPT-45F

A MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels down to the lower voltage needed to charge batteries.
