inputs are grouped into three 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. Then the inputs are grouped into two MPPT routes inside the SUN2000 to
track the maximum power point of the PV strings.
After that, the DC power is converted into three-phase AC power through an inverter circuit.
Surge protection is supported on both the DC and AC sides. See Figure 2-10, Figure 2-11, and
Figure 2-12.
