We make custom MC4 extension wires for you, any length, you tell us what you want on the ends (one MC4 connector, or a connector on each end). We can make them in red or black wire.
The connectors we use are always the real, official, Multi-Contact brand MC4 connectors. The wire is 10 AWG 1000 Volt rated “PV-Wire” stamped, CSA and UL approved for Canada and the USA.
Current pricing for custom MC4 extension cables is $1.50 per foot & $5 per MC4 connector ($20 minimum order).
