+ | ===== MPPT tracking sweeps ===== | ||
+ | An **MPPT** controller sweeps the **P**ower **P**oints along the array voltage curve in order to **T**rack the **M**aximum (and non-maxiumum) power points. | ||
+ | |||
+ | Depending on the algorithm the sweep may be local to the present Vpanel, or may be a sweep from 0v-Voc, or anything in between. | ||
+ | |||
+ | The sweep will interfere with power production so the mfg attempts to find a balance between | ||

+ | * constant production, and | ||
+ | * learning whether or not one is operating at the ideal power poing | ||
