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 mini-
mum bending radius during wiring .
5.6.1 PV Input Configuration
•
The inverters SG5.0RS-ADA/SG8.0RS/SG9.0RS/SG10RS have three PV inputs, each
with independent 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.
