Solar Energy Cable Single Core 4mm² Black XLPE AD7 - 50m Reel

Product Overview

The Solar Cable SOLAR1X4BKR50/AD7 is a 50m Reel of 4mm² single-core solar energy cable designed for reliable DC wiring in photovoltaic (PV) systems and related electrical installations. Constructed with a flexible tinned copper conductor and rugged XLPE (cross-linked polyethylene) insulation and sheath, this cable delivers durable performance for fixed internal or external cabling between solar modules, junction boxes, combiner units and inverters. It meets the harmonised H1Z2Z2-K solar cable standard and complies with BS EN 50618, ensuring long service life and safety in solar environments. This cable’s XLPE insulation provides excellent resistance to UV exposure, ozone, moisture, and temperature variations, rendering it suitable for rooftop, conduit, or tray installations. Halogen-free, flame-retardant construction improves safety in both commercial and residential environments, while its flexible design supports straightforward on-site routing and termination. Rated for up to 1800 V DC and 600 V-1000 V AC, this cable delivers dependable performance among a range of solar DC applications. The 50m Reel format offers an installer-friendly length for mid-range runs, reducing joins and speeding installation in PV arrays, battery connections or DC distribution wiring.
