5.6.1 PV Input Configuration
• The inverters SG5.0RT/SG6.0RT have two PV inputs, SG7.0RT/SG8.0RT/SG10RT/
SG12RT have three PV inputs and SG15RT/SG17RT/SG20 have four PV inputs.
• The inverters have two MPP trackers. Each DC input area can operate independently.
• The PV strings to the same DC input area should have the same type, the same
number of PV panels, identical tilt and identical orientation for maximum power.
• The PV strings to two DC input areas may differ from each other, including PV
module type, number of PV modules in each string, angle of tilt, and installation
orientation.
FFiigguurree 55--33 PV Input Configuratinon (SG20RT for example)
Prior to connecting the inverter to PV inputs, the specifications in the following table
should be met:

The following figure shows the open-circuit voltage limits at different altitudes. Before
configuring the PV panels, need to take this derating curve in consideration under high
altitude situation.
