2.4 Working Principles
Schematic Diagram
The SUN2000 receives inputs from up to two PV strings. Then the inputs are
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 single-phase AC
power through an inverter circuit. Surge protection is supported on both the DC
and AC sides.
The SUN2000 uses a reserved battery port for energy storage expansion. Battery
performs charging and discharging operations according to the battery working
mode.
