Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking ( MPPT ), [ 1][ 2] or sometimes just power point tracking ( PPT ), [ 3][ 4] is a technique used with variable power sources to maximize energy extraction as conditions vary [ 5]. The technique is most commonly used with ...
By way of example, a 150 volt PV array connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller. [citation needed] Charge controllers may also monitor battery temperature to prevent overheating.
Basic charge controllers may simply turn the PV panels on and off, or may meter out pulses of energy as needed, a strategy called PWM or pulse-width modulation. More advanced charge controllers will incorporate MPPT logic into their battery charging algorithms. Charge controllers may also divert energy to some purpose other than battery charging.
A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the ...
