Risk of inverter damage! Observe the following requirements. Failure to do so will
void guarantee and warranty claims.
• Make sure the maximum DC voltage and the maximum short circuit current of
any string never exceed inverter permitted values specified in "Technical Data".
• Mixed use of different brand or model of PV modules in a PV string or a compro-
mised PV string design composed with PV modules from rooftops of different
orientation may not damage inverter but will cause system bad performance!
• The inverter enters standby state when the input voltage ranges between 1,000
V and 1,100 V. The inverter returns to running state once the voltage returns to
the MPPT operating voltage range, namely, 160 V to 1,000 V.
5.6.1 PV Input Configuration
• The inverters SG3.0RT/SG4.0RT/SG5.0RT/SG6.0RT have two PV inputs, SG7.0RT/
SG8.0RT/SG10RT/SG12RT have three PV inputs and SG15RT/SG17RT/SG20RT 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.

Prior to connecting the inverter to PV inputs, the specifications in the following table should
be met:
