Which connector do I need?
Select the connector that matches your PV wire gauge. The 10 & 12 AWG connector bag is compatible with our most popular 10 AWG PV Wire 2000V and 12 AWG PV Wire 2000V. For larger conductor runs, the 8 AWG connector is designed for use with 8 AWG PV Wire 2000V.
Crimping tools
Proper crimping is essential for reliable MC4 connections. Our crimping tool sets are matched to the connector size — the 10 & 12 AWG tool set for smaller gauge wire, and the 6 & 8 AWG tool set for larger conductors. Using the correct tool ensures the crimp meets the mechanical and electrical requirements for outdoor photovoltaic installations.
Recommended applications
- Solar panel to string wiring connections
- Module-to-module jumper connections
- String-to-combiner box DC connections
- Residential and commercial rooftop PV systems
- Ground-mount solar array wiring

Frequently asked questions
Are these true MC4 connectors?
These are MC4-type connectors rated at 1,500V and UL6703 listed. They are designed to be compatible with standard MC4 solar panel connectors used in photovoltaic systems.
How many connectors come in each bag?
Each bag contains 50 pairs (100 individual connectors — 50 male and 50 female).
Do I need the crimping tool?
Yes. MC4 connectors require a dedicated crimping tool for proper installation. Using a standard crimping tool will not produce a reliable connection and may void the connector warranty.
Are these connectors compatible with all PV wire brands?
Yes, provided the wire gauge matches the connector size. They are compatible with our UL4703 copper PV wire and other UL4703-listed PV wire of the same gauge.
