2.4 Working Principle
Conceptual Diagram
The SUN2000 receives inputs from eight PV strings. Then the inputs are grouped into four
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. Figure 2-9 shows the SUN2000
conceptual diagram.
