20A MPPT Solar Charge Controller

20A MPPT Solar Charge Controller ■ The MPPT is essentially a smart DC to DC converter which has been optimized to harvest maximum energy from the PV array in battery based solar electric systems by using a variety of maximum power point tracking (MPPT) strategies. ■ The controller’s secondary objective is to ensure that the batteries receive a full charge without becoming overcharged.This is accomplished through a four stage charging process.
