6mm² Solar Cable Twin Core - 20 meters with MC4

6mm² Twin Core Double-Insulated Tinned Copper Solar Cable – 20M Roll

This premium 6mm² twin core solar cable is designed for high-performance solar installations, providing a reliable DC connection between photovoltaic panels, combiner boxes, charge controllers, and inverters.

Featuring double insulation and tinned copper conductors, this cable is engineered for durability in harsh outdoor environments, making it ideal for off-grid and grid-tied systems.

Key Features

Twin Core Design (Positive & Negative in One Sheath)
Two insulated conductors housed within a single outer sheath for neat, professional installations and simplified cable management.

Double-Insulated Construction
Enhanced protection against UV exposure, moisture ingress, and mechanical damage — suitable for rooftop and outdoor applications.

Tinned Copper Conductors
Superior corrosion resistance compared to bare copper, making it ideal for coastal and high-humidity environments.

Solar Certified
