Why Choose H1Z2Z2-K Solar Cable?

The H1Z2Z2-K standard (EN 50618) is the modern successor to the older PV1-F cable, designed specifically for today's high-performance PV systems. Key advantages:

  • Higher voltage rating: DC 1.5 kV (up to 1800 V max) – ideal for modern 1500V systems.
  • Improved durability: Double insulation with cross-linked polyolefin, thicker sheath for better mechanical protection.
  • Superior water resistance: AD8 rating – fully submersible and suitable for direct ground installation.
  • Extreme temperature range: -40°C to +90°C (short-term up to +120°C conductor temperature).
  • Halogen-free & low smoke: Enhanced fire safety (class Dca per EN 13501-6).
  • Tinned copper conductors: Corrosion-resistant for long-term reliability in outdoor environments.

H1Z2Z2-K vs PV1-F: Key Differences

Feature H1Z2Z2-K (EN 50618) PV1-F (Older Standard)
Voltage Rating DC 1.5 kV / AC 1.0 kV DC 1.0 kV / AC 0.6 kV
Insulation Double cross-linked polyolefin Single insulation
Water Resistance AD8 (permanent submersion) AD7 (temporary submersion)
Sheath Thickness Thicker for better protection Thinner
Typical Use Modern large-scale PV systems Older/smaller installations

Recommendation: For new installations, always choose H1Z2Z2-K for future-proof performance and compliance with current standards.

Choosing the Right Cross-Section (qmm)

  • 4 mm²: Ideal for short runs and smaller residential systems (up to ~30A).
  • 6 mm²: Most popular – balances cost and performance for medium to large arrays (up to ~40A).
  • 10 mm²: For long cable runs or high-power commercial systems to minimize voltage drop.

Compatible with standard MC4 connectors (we also offer matching MC4 PV connectors for 4-6 mm² cables).
