2.4 Working Process
Circuit Diagrams
The SUN2000 receives inputs from six PV strings. Then the inputs are grouped into three
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. Surge
protection is supported on both the DC and AC sides.
