three maximum power point tracking (MPPT) routes inside the SUN2000 to track the 
maximum power point of the PV strings. 
 
The SUN2000-8KTL, SUN2000-10KTL, and SUN2000-12KTL receive inputs from four 
PV strings. The inputs are then grouped into two 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 a converter circuit. There 
is surge protection for both DC and AC sides. Figure 2-10, Figure 2-11, and Figure 2-12 show 
the circuit diagrams for the different models.
