Solar cabling & connectors
The parts that tie an array together are small but safety-critical. We stock double-insulated solar DC cable, genuine and compatible MC4 connectors, crimping tools, and the in-line fuses and isolators every install needs.
Match the connector to the cable: 2.5mm², 4mm² and 6mm² solar cable each need the correct MC4 crimp barrel. Our MC4 guide covers sizing, crimping and how to spot genuine connectors.

Which MC4 connector fits my cable?
Match the connector to the cable cross-section — 2.5mm², 4mm² or 6mm² — because each needs the correct internal crimp barrel. Our MC4 guide explains sizing and crimping.
Can I mix MC4 connectors from different brands?
No — never mate two different connector brands in the same joint. They may look compatible but make poor contact, which is a common cause of hot joints. Keep each connection brand-consistent.
