Solar MC4 Extension Cable 3m

This 3-metre extension cable connects a solar panel to a grid-tie inverter using one male and one female MC4 connector on one end and copper terminals on the other. The pair of black and red cables suits installers who need a ready-made link between standard PV connectors and inverter screw terminals.

MC4 Connector Current Limit

The cable is rated for 30 A and uses 4 mm² conductors, so the practical limit is the connector rating rather than the wire gauge. The 6 mm terminal hole diameter (0.236") matches the specified inverter terminals, and double seal rings provide waterproof and dust-proof protection for outdoor exposure.

30 A Capacity and Headroom

The assembly handles continuous currents up to the rated 30 A with low contact resistance and strong pulling-force capability. It runs out of headroom when the array current exceeds that rating or when the inverter requires a different terminal size, so systems needing higher current or alternative connector types cannot use this cable.

Questions about this item

Should I choose the 3 m length or a different cable run for my grid-tie inverter?

The kit ships as a single 3 m pair — one black and one red lead — each terminated with an MC4 plug on one end and a copper terminal on the other, so the length is fixed at 3 m.

What does the 30 A rating mean once the cable is connected to my inverter?

The 4 mm² conductors are rated for 30 A continuous current, allowing the extension to carry full inverter output without overheating when the MC4 and terminal connections are properly tightened.

How does the MC4-to-terminal interface limit what I can connect?

One end uses a standard MC4 pair for panel-side linking, while the opposite end provides copper terminals with a 0.236 in round centre hole that bolt directly to the inverter’s DC input busbars.
