MC4 Solar Connectors & Branch Couplers

MC4 connectors are the industry standard for joining solar panels, cables, controllers and inverters with a secure, weatherproof click. They create a watertight, low-resistance connection that holds up outdoors for years, which is why nearly every modern panel uses them. Our carefully selected range covers standard pairs, branch connectors and assembly tools.

Match pairs and ratings

MC4 connectors come as male and female pairs. Make sure they match your cable gauge and the system current and voltage. Using the correct rating keeps the joint cool and safe under load.

Branch and parallel connectors

Y-shaped branch connectors let you wire panels in parallel to boost current. Choose these when your design calls for combining strings rather than a single series run.

Proper assembly matters

A correctly crimped and clicked MC4 connector is watertight; a loose one can corrode, overheat or arc. Use the right crimping tool and pair connectors with quality Solar PV Cables. For lighting your install, see LED Floodlights. Browse the full Solar & Photovoltaic range, and explore Lighting too.
