Note the following items when laying out cables on site:
• The axial tension on PV connectors must not exceed 80 N. Avoid axial cable
stress on the connector for a long time during field wiring.
• Radial stress or torque must not be generated on PV connectors. It may cause
the connector waterproof failure and reduce connector reliability.
• Leave at least 50 mm of slack to avoid the external force generated by the cable
bending affecting the waterproof performance.
• Refer to the specifications provided by the cable manufacturer for the minimum
cable bending radius. If the required bending radius is less than 50 mm, reserve
a bending radius of 50 mm. If the required bending radius is greater than 50 mm,
reserve the required minimum bending radius during wiring.
5.6.1 PV Input Configuration
• The inverters SG8.0RS-L/SG9.0RS-L/SG10RS-L have three PV inputs, each with inde-
pendent MPP tracker. Each DC input area can operate independently.
• The PV strings to each DC input 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:
