Amizar 4mm² solar DC cable is purpose-made for the DC side of a solar installation. Solar cable is built to sit outdoors on a roof for years.

Key Features

• 4mm² conductor: The standard size for residential and small commercial solar strings, carrying panel current with minimal voltage drop over a normal roof-to-inverter run.

• UV-resistant insulation: Built to survive years of direct sunlight without cracking or going brittle — the exact failure that kills ordinary house cable on a roof within a season or two.

• Weatherproof and outdoor rated: Resists rain, dust, heat and cold, so it can run exposed along a roof or down an outside wall.

• High temperature rating: Rated well above ambient, because the space behind a solar panel gets far hotter than a wall cavity ever does.

• Tinned copper conductor: Tinning resists corrosion at the terminations and in damp conditions, keeping connections sound over the life of the system.

• Double insulated: Extra mechanical protection against abrasion on roof sheets, rails and edges during and after installation.

• Flexible for easy routing: Bends neatly around panel frames, through rails and into combiner boxes without kinking.

• Red for positive: Correctly colour-codes the positive run so polarity is obvious at every junction — pair it with black for negative.

• Compatible with MC4 connectors: The standard 4mm² size crimps into MC4 connectors used on virtually every solar panel sold.

• 100 metre roll: Enough cable for a full residential array with spare, so an installer isn't caught short mid-job.
