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.
