Sungrow can provide Bizlink's Y-branch connector. If necessary, please contact
Sungrow to purchase. Customers can also purchase Y-branch connector of the same
specification by themselves. The wiring instructions for Y-branch connector are as
follows.
•
When choosing to purchase Y-branch connector from Sungrow, unifacial module
use Y-branch connector with 15A fuse, and the material number is B-Q-002567;
bifacial module use Y-branch connector with 20A fuse, and the material number is
B-Q-002568.
•
When Y-branch connector is used for wiring, all connectors must be matched by the
same manufacturer, and different manufacturers shall not be mixed. Mixed use will
cause the contact resistance of the connector to exceed the allowable value, and the
connector will continue to heat and oxidize during use, which is very prone to failure.
•
The Y-branch connector can be connected at the module side or the inverter side.
•
Sungrow provides Y-branch connector of Bizlink, whose terminal is MC4-Evo2.
When it is connected at the inverter side, the Y-branch connector can be directly
connected to the inverter.
•

sectional area is 4mm
2 or 6mm 2 .
