If your solar panels have Tlian T6 connectors (common on Canadian Solar modules), you need extension cables with the same connectors – not MC4. Mixing connector brands is where heat builds up and failures start.
What you get:
- Both positive and negative connectors on the same cable – one male, one female
- Standard black PV wire – not red/black color-coded
- Available lengths: 6 feet to 150 feet (standard sizes)
- Custom lengths available – call us with your exact needs
Two ways to use them:
- Use them whole – As extension wires between panels or from array to combiner box
- Cut them in half – To create two lead wires (positive and negative) for landing on a circuit breaker or bus bar
Why buy from us: Professionally crimped, weather-sealed, and ready to plug in. No special tools required.
