There is a risk of inverter damage! The following requirements should be met;
otherwise they will lead to loss of any and all warranty rights.
y
Make sure that the maximum short circuit current of each DC input is less than
inverter allowable limit.
y
Make sure that the maximum open voltage of each string is less than 600V.
Voltage over 600 V can damage the inverter.
5.5.1 PV Inputs Configuration
-S Series
There is one input area with one MPP tracker. Only one input can be connected, as
shown in the following figure.

-D Series
There are two PV input areas, each with its MPP tracker. The two PV inputs can be
configured in independent mode or parallel mode.
y
Independent Mode
The two PV inputs work independently, each with its own MPPT. The two PV inputs
can be different from each other in PV module types, numbers of PV panels in PV
string, tilt angles and orientation angle of PV modules.
