What is Maximum power tracking?

Sometimes referred to as peak power tracking. Operating a solar generator at the maximum power point of the PV system's current-voltage characteristic, where peak power is obtained. Older and some modern small inverters have only one MPPT, meaning that all solar modules connected to the inverter have to face the same direction. In case of shading, they suffer from the same losses. As for larger inverters, most of them have two trackers, which allows different strings of modules to face different directions and not to be affected by one another.
