- Product Details
4mm solar cable is designed for solar power system.4mm” refers to the cross-sectional area of the cable, indicating 4mm dc solar cable gauge. 4mm or 6mm solar cable is consists of multiple strands of tinned copper. The insulation and sheath are XLPO(Cross linked polyolefin). “Double XLPO provides protection against moisture and ensures long-lasting performance in harsh environments.That is why 4mm twin solar cable can be used for outdoor. Available color is red and black, other colors can be customized.

FAQ
What is a 4mm solar cable used for?
A 4 mm solar cable is used for DC power transmission between solar panels and in PV system interconnections.
What is the current carrying capacity (Ampacity) of 4mm² solar cable?
According to EN 50618, a single 4mm² solar cable in free air (at 60°C ambient temperature) typically has a current rating of approximately 55 Amps.
Why is the conductor made of Tinned Copper instead of Bare Copper?
Tinned copper is essential to prevent galvanic corrosion and oxidation over the system's 25-year lifespan. Bare copper reacts with the insulation and moisture over time, leading to increased resistance and potential connection failure.
