Helukabel

Helukabel make the cable that carries the current in a solar system, and using proper solar cable rather than general purpose flex is not optional: DC strings run hot, sit in sunlight for twenty years and cannot be protected by an ordinary fuse.

Hikra-Sol PV cable comes in 4mm2, 6mm2 and 10mm2 on 100m and 500m drums, in red and black pairs. Flexible battery cable runs from 16mm2 up to 150mm2 for inverter and battery bank connections, where voltage drop over a short run is what sizes the conductor. NYY-J armoured AC cable covers the run from inverter back to the consumer unit.
