2.3 Working Principles
Schematic Diagram
The inverter receives inputs from up to two PV strings. Then the inputs are grouped into two
MPPT routes inside the inverter 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 inverter uses a reserved battery port for energy storage expansion. Battery performs
charging and discharging operations according to the battery working mode.
