Module and string wiring
Join module leads and field cables with matching cable connector pairs.
Solar Connectors / product groups
Solar connectors for module leads, branches and inline fuses.
Connect PV cables, bring a connection through a panel, or join parallel strings with T and Y branches. Inline fuse connectors provide a separate option for string protection.
- PV cable connector pairs
- Panel-mount connectors
- T and Y branches

Choose the connection for your PV circuit.
Cable pairs join module leads and string wiring. Panel connectors mount through an enclosure, branch connectors join parallel paths, and fuse connectors hold an inline protective device.
Standard PV Cable ConnectorsPV-01 through PV-07 cable connectors and a panel-mount form for module leads and string wiring.Match the connector pair, conductor cross-section and cable outside diameter.
PV Branch ConnectorsT and Y connectors that join parallel PV strings, with different branch counts and connector layouts.Choose the number of branches and polarity for your PV cable layout.
PV Functional ConnectorsAn inline PV fuse connector for string-circuit protection.Choose the fuse rating for the PV string current and system voltage.Selection guide
Match the mating pair, cable and PV circuit.
Use connector parts approved to mate with each other. Then match the contact to the conductor size, the seal to the cable diameter, and the rating to the circuit.

Applications
PV modules and string wiring.
Connect module leads, route string cables through panels and bring parallel strings together.
Parallel string connections
Use T or Y branches to bring parallel strings together.
String fuse connections
Add an inline fuse connector where the circuit design calls for string protection.

Solar Connectors FAQ
Product selection questions
Find answers about the differences between product types and how to choose a model.
01Can I mate solar connectors that look the same?
Appearance does not establish compatibility. Use a connector pair approved by its manufacturer, with the specified contacts, seals and assembly tools.
02When should I use a T or Y branch connector?
Use one where the PV circuit joins parallel strings. Choose the branch count and polarity to match the layout, and account for the combined current.
03Are cable cross-section and cable diameter the same selection value?
No. Conductor cross-section determines the contact size; cable outside diameter determines the sealing fit. Both are needed to select a cable connector.
