NOTICE
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.
5.8.1 PV Input Configuration
As shown in the figure below, the inverter is provided with multiple PV inputs: PV inputs 1~9;
and each PV input is designed with an MPP tracker.
Each PV input operates independently and has its own MPPT. In this way, string structures of
each PV input may differ from each other, including PV module type, number of PV modules
in each string, angle of tilt, and installation orientation.
Each PV input area includes two DC inputs DC1 and DC2. For the best use of DC power,
DC1 and DC2 should be the same in PV string structure, including the type, number, tilt, and
orientation of the PV modules.
