## Long description

SOLARFLEX®-X Ballast Vads EN50618 H1Z2Z2-K Cu 4 mm² is a single-core copper cable intended for DC connections in photovoltaic systems and rooftop installations. Manufactured to EN50618 standards, the cable is designed for outdoor use with materials that resist ultraviolet radiation and common weather conditions. The conductor size and construction provide consistent electrical conductivity for connecting solar modules, string combiners and inverters in residential and commercial PV arrays.
Advantages
The cable features a single-core 4 mm² copper conductor with insulation and sheath suitable for solar DC applications, combining flexibility with stable electrical performance. Conformance to EN50618 ensures the materials and build meet industry requirements for UV and weather resistance, while the cable’s copper conductor supports low electrical losses in short- and medium-length runs. Its construction simplifies installation on rooftops and in cable trays where a dedicated solar DC cable is required.
Suitable for
Connecting photovoltaic modules in series (string wiring)
Linking string combiner boxes to inverters and junction boxes
Rooftop PV cable runs exposed to sunlight and weather
Short- to medium-length DC feeder circuits in solar installations
Key specifications
Conductor material: copper (Cu)
Number of cores: single-core
Conductor cross-section: 4 mm²
Standard: EN50618 solar DC cable construction
Insulation and sheath: UV- and weather-resistant materials suitable for outdoor PV use

How to use
Route the SOLARFLEX®-X 4 mm² single-core cable between modules, combiner boxes and inverters following applicable electrical codes and PV installation standards. Use appropriate cable glands, connectors and MC4-compatible termination components rated for DC photovoltaic systems. Ensure correct polarity marking and secure fastening along roof mounts or cable trays to prevent mechanical strain. Observe minimum bending radii during installation and avoid sharp kinks or pinch points.
Usage recommendations
For reliable long-term performance, install the cable in accordance with EN50618 guidelines and local electrical regulations. Use appropriate overcurrent protection and DC-rated connectors, keep conductor lengths and voltage drop within design limits, and perform periodic inspections for UV ageing, mechanical damage and connector integrity.
