2.3 Working Principle
The PV string input is connected to the inverter, and the maximum power point for the PV string is
tracked through the internal 10 groups of MPPT circuits to achieve the maximum power output of the
PV string, and then the conversion of DC power to three-phase AC power is realized through the
inverter circuit, as shown in Figure2-7.
