• 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.
