4.1. Maximum Power Point Tracking (MPPT)
A PV inverter must be able to convert the maximum power from any PV panel. Due to its advanced design, this
PV inverter can track the maximum power from the PV panel in any condition. When the displayed power on
the LCD output does not change dramatically, the Inverter is converting the maximum power from panels.
When the LCD power reading is significantly changes, the Inverter is tracking the power according to the varied
sunlight.

When the PV panel’s output is low, the feeding DC-power may drift slowly as does the AC power. It is
because PV inverter is tracking maximum DC-power constantly.
