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 2-10 shows the conceptual 
diagram for the SUN2000-33KTL-A/36KTL. Figure 2-11 shows the conceptual diagram for 
the SUN2000-42KTL.
