2.4 Working Principles
2.4.1 Circuit Diagram
The inverter receives inputs from 18 PV strings. Then the inputs are grouped into
nine MPPT circuits inside the inverter to track the maximum power point of the PV
strings. The DC power is then converted into three-phase AC power through an
inverter circuit. Surge protection is supported on both the DC and AC sides.
