2.4.1 Circuit Diagram

The SUN2000 receives inputs from 12 PV strings. The inputs are grouped into 6 MPPT
circuits 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.
