In order to operate in the parallel mode from a common array, it is necessary
to electrically connect the input channels in parallel using the jumper cables
provided with this inverter.
In addition, the input mode switch
S1
located on the inverter connection board
must also be set to the parallel mode as described below.
S
etting the input mode switch S1
The input mode switch
S1
located on the inverter connection board is used to select the input
configuration. The default position of the S1 switch is set in the IND mode (DOWN position).
In this mode up to four strings can be connected (two per input) without need of external
combiner fusing
To operate the inverter in the parallel MPPT mode
place S1 switch UP in the PAR position.
Note that only two strings can be directly connected to
the inverter in this mode. If more than two strings are
required, all strings must be combined in an external
fused combiner box, or the IND mode must be used.
Use the following instructions to electrically connect the input channels in parallel.

AFD
In the switchbox,
parallel the two MPPT inputs of terminal [–IN1 and –IN2] and [+IN1 and
+IN2] as shown below using the two #10 AWG jumper wires provided (1 black and 1 red
cable) to connect the input.
NOTE!
When Arc Fault Detection (AFD) is installed, the paralleling must be done
inside the inverter as shown on the following page..
