Why this product
A one-metre MC4 extension lead — the shortest in the range, and the one you want when the factory leads almost reach.
The gap this closes
Module junction box leads are cut to a standard length that assumes the inverter sits directly behind the panel. Real mounting rarely cooperates. The inverter ends up one rail over to clear a bracket, or the module is portrait when the leads were sized for landscape, and suddenly you are 40cm short. A metre solves that without leaving a metre and a half of surplus to dress.
Why not just buy long and coil the rest
Excess DC cable on a solar array is not harmless. Coiled conductors carrying DC form an inductive loop, loose loops flap in wind and fatigue their terminations over years, and slack that dips below the frame collects standing water at the low point. Sizing close to the actual run is better practice than buying one long length for everything.
Practical notes
- MC4 connectors are polarised — one lead extends positive, one negative
- Every extension adds two more connections, and connections are the usual suspects in DC fault-finding. Seat them properly and confirm the click
- Support the cable on the frame rather than letting it hang on the connector
Also available in 2m, 3m and 4m. Confirm connector compatibility — MC4-style connectors from different manufacturers are not always cross-matable, and mixing brands is a known failure mode.
