This section describes the SUN2000 working process.
Circuit Diagrams
The SUN2000-33KTL/40KTL 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. The
SUN2000-40KTL has three-phase, three-wire (L1, L2, and L3) output without a neutral wire.
