2.4.1 Conceptual Diagram

The SUN2000 receives inputs from 12 PV strings. Then the inputs are grouped into six MPPT
routes inside the SUN2000 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.
