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.
