Scenario
Model of Y-branch
Connector (Part A)
Connection Description
Connecting Y-branch
connectors to the PV
strings (recommended)
All models
Use the DC terminals delivered with the
SUN2000s to connect part B to the SUN2000s.
Connecting Y-branch
connectors to the
SUN2000
Models recommended
by Huawei
Part A can be directly connected to the
SUN2000, and part B is not needed.
Other models
To ensure that the terminals of part A match
the DC terminals of the SUN2000, part B is
needed to connect part A to the SUN2000. Use
the DC terminals delivered with the SUN2000
to connect part B to the SUN2000.
•
It is recommended that the Y-branch connectors be connected from the PV string side and
tied to the PV trackers.
•
The DC input terminals of the solar inverter are prone to damage under stress. When Y-
branch connectors are connected to the solar inverter, bind and secure the connectors to
minimize stress on the DC input terminals.
•
Do not place the Y-branch connector harness on the ground. A safe distance must be
reserved between the Y-branch connector harness and the ground to avoid impact caused by
water on the ground to the harness.
