Frequently Asked Questions

Answers to the most common PV cable selection questions from EPC contractors, distributors and installers.

Which PV cable is right for a residential rooftop system?
For rooftop residential systems, H1Z2Z2-K (Eca) is the standard choice for PV string connections — it is single-core, double-insulated and rated for outdoor UV exposure. H05V-K handles inverter and control wiring, H07V-K covers internal installation and grounding conductors, and N2XH is used for halogen-free building cable runs.
What do the Eca, Dca and Cca markings on PV cable mean?
Eca, Dca and Cca are reaction-to-fire classifications under the EU Construction Products Regulation (CPR) for cables installed in buildings. Cca and Dca indicate progressively higher fire-performance requirements than Eca and are typically specified for commercial, industrial and utility-scale installations with denser cable runs.
What is the difference between H1Z2Z2-K and H07V-K cable?
H1Z2Z2-K is a halogen-free, double-insulated cable purpose-built for outdoor PV string connections between modules and combiner boxes/inverters. H07V-K is a general-purpose single-insulated conductor used for internal installation wiring and grounding inside enclosures — it is not rated for permanent outdoor PV string exposure.
Can PV cables be installed underground?
Yes. NYY-J is designed for underground power distribution runs on commercial and industrial sites, and utility-scale PV plants commonly use underground collector networks built with NA2XH aluminium distribution cable for long-distance runs between array sections and the substation.
What cable is used for battery energy storage (BESS) DC connections?
NA2XS(F)2Y is the dedicated DC battery connection cable for utility-scale PV and BESS installations, rated for systems up to 1.5 kV DC. It is engineered for the higher insulation and mechanical demands of battery interconnection compared to standard PV string cable.
Are these PV cable systems compliant with international standards?
Yes. The cable systems are manufactured to IEC EN and VDE standards, and the lineup holds TUV, UL, RoHS, REACH and CPR certification. The product family has over 250,000 km of field-proven global installations across residential, commercial and utility-scale PV and energy storage projects.
