When your array sits a panel-width away from the charge controller, inverter or junction point, what you need is not a spool of wire and field crimping - you need a finished, tested jumper. This Solar MC4 Extension Cable is exactly that: ten feet (3 m) of 6 mm² double-insulated photovoltaic wire, terminated at each end with a male and a female MC4-type connector, crimped and sealed in our own plant with calibrated tooling.
Compared with generic solar extension cord offerings, the 6 mm² conductor keeps voltage drop negligible even on high-current strings, and the cross-linked, UV-stable jacket is rated for 1,500 V DC rooftop exposure. Installers also use it as a photovoltaic adapter wire to bridge mismatched lead lengths between panels, combiner boxes and portable power stations - plug, click, done.

Extending panel leads to charge controllers or inverters in RV, marine, balcony and off-grid kits - the classic Solar MC4 Extension Cable duty
Service loops left for future maintenance, without cutting and re-crimping in the field
Copper is procured as 99.99 % purity rod and re-verified against IEC 60228 resistance before stranding; every termination is crimped with calibrated dies, then pull-tested, continuity-checked and high-voltage tested, with mated-pair IP68 verified on sample basis each lot. Every solar extension cord ships with traceable batch records and a factory test report, and a replacement guarantee covers any reel or jumper that fails your incoming retest.
We also give straight engineering guidance: MC4-type connectors physically mate across brands, but long-term outdoor reliability and certification logic favour identical connector pairs - which is exactly how our jumpers are terminated. Honest advice like this prevents the corroded, high-resistance joints that cause hot spots years later.
Factory-direct pricing with stable copper sourcing and short lead times
Batch-level traceability and responsive after-sales engineering
Physically yes, but we recommend keeping connector pairs identical. IEC 62852 certification applies to matched connector types, and mixed-brand MC4-style pairs are the most common cause of high-resistance, water-ingress failures in the field. Our jumpers arrive pre-mated with identical pairs, so your joint is as good as the factory can make it.
Is 10 ft long enough, and what about voltage drop?
At 6 mm² the drop over 10 ft is negligible for typical string currents. For longer runs, calculate drop at your operating current - or simply order a custom length in the same construction rather than daisy-chaining jumpers.
Yes. The cross-linked jacket is UV and ozone stable for rooftop exposure, and mated connectors hold IP68. Do not leave unmated connectors exposed to weather for extended periods; cap them if a run stays open during installation.
Send your required length, polarity and quantity to our sales engineers. Within 24 hours you receive a datasheet, factory-direct pricing and a sample Solar MC4 Extension Cable built to your exact specification - the same tested solar extension cord and photovoltaic adapter wire your installation deserves.
