Wiring illustration for type-Y PV connector
When wiring by type-Y PV connector, the type of all connectors must match that of the inverter. If
using the connector with different manufacturer or different type together, the contact resistance of the
connector may exceed the allowable value, it will continue to heat and oxidize and easy to break down.
Wiring principle:
l
For each MPPT, at most one set PV connector of type-Y can be connected.
l
The PV+ of inverter side must be connected to the PV+ of PV string side, the PV- of inverter side
must be connected to the PV- of PV string side. They cannot be connected mixed.
