5.2 Grid-connected Operation
Prior to grid connection of the inverter, please confirm if the wirings
among input side of inverter, PV arrays, output side and power grid are
all correct. Three kinds of modes are optional for connection
between DC input side of KSG-32K grid- connected inverter and PV
arrays:
﹡
Independent input mode: three groups of different PV arrays may
be connected to input end of inverter and independent MPPT
controller is available for each group of PV arrays to control grid-
connected operation.
Figure 4: Independent Input Mode
﹡
Parallel input mode: only one group of PV arrays is connected
with input end of the inverter, which is then connected to input side
of inverter via three groups of parallel input terminals.
