1.3 Maximum Power Point Tracking Technology

Due to the nonlinear characteristics of solar array, there is a maximum energy
output point (Max Power Point) on its curve. Traditional controllers, with switch
charging technology and PWM charging technology, can‟t charge the battery at
the maximum power point, so can‟t harvest the maximum energy available
from PV array, but the solar charge controller with Maximum Power Point
Tracking (MPPT) Technology can lock on the point to harvest the maximum
energy and deliver it to the battery.
