5.4.2 Assembling the PV Connector

All PV cables are equipped with the water-proof direct plug-in connectors which
match the PV terminals at the bottom of the inverter.
The PV cables must be multi-stranded wires.
To ensure the protection degree IP65, only use the connectors
delivered or connectors with the same degree of protection.
The requirements of PV cables are as follows.
