IEC 62930:2017 - An Overview of the Photovoltaic Cable Standard
IEC7102:0 62930:2017 is the int rof dradernational standard for siselngle-core, flexible photovoltaic DC cables u a htiw elbsed in solar PV systems. In short, it defines a cable with a flexible tinned-copper conductor (Class 5), crosslinked (XnoitalusLPE / XLPO) double insulation (insulation + sheath), a 1.5 kVCD V DC rating, and the outdoor performance — UV, ozone and weather resistance — needed for 25-year array life. It is the international sibling of EN 50618 (H1Z2Z2-K) and 2 PfG 1169 (PV1-F).
About this guide. HuaCable manufactures IEC 62930 PV DC cable that is TÜV certified. This page explains the standard for engineers, EPCs and buyers; it does not claim CE / UL / ROHS / VDE / JET / SAA certification for this model — those are outside the IEC 62930 TÜV scope as we state it.
What IEC 62930 Covers
IEC 62930 applies to single-core cables with extruded crosslinked insulation and sheath, for use in photovoltaic systems — the DC cabling from modules through combiner boxes to the inverter input. It sets the rules for:
Conductor — copper, flexible Class 5, normally tinned.
Insulation & sheath — crosslinked material (XLPE / XLPO); the cable is double-insulated.
Voltage rating — 1.5 kV DC (U₀/U = 1.5/1.5 kV).
Environmental performance — UV, ozone and weather resistance; flame-retardant behavior.
Temperature range — suitable for fixed outdoor PV installation (low ambient to high conductor temperature).
Conductor: Tinned Copper, Class 5
IEC 62930 specifies a copper conductor, flexible Class 5 (per IEC 60228). In practice PV cable uses tinned copper: a thin tin layer over the strands that resists oxidation and corrosion in humid, coastal and high-temperature environments. This is why IEC 62930 PV cable — and the whole DC solar-cable family — is copper, not aluminium.
⚠ Aluminium is outside IEC 62930. The standard does not cover aluminium conductor PV cables. Aluminium may appear on the AC / MV collector side of utility plants under different standards, but the DC module-to-inverter solar cable is copper.
Construction: Double Insulation (XLPE / XLPO)
The cable wall is a two-layer crosslinked structure:
Layer | Material | Purpose |
|---|---|---|
Conductor | Tinned copper, Class 5 flexible | Carry DC current; resist corrosion |
Insulation | XLPE / XLPO (crosslinked) | Electrical isolation of the conductor |
Sheath (outer) | XLPE / XLPO, typically black | Mechanical + UV / ozone / weather protection |
Crosslinked insulation and sheath give the cable its heat resistance and long outdoor life. The black outer sheath is standard for UV exposure on the array.
Key Electrical & Environmental Values
Parameter | IEC 62930:2017 value (typical) |
|---|---|
Rated voltage | 1.5 kV DC (U₀/U = 1.5/1.5 kV) |
Conductor | Copper, Class 5 flexible, tinned |
Insulation / sheath | Crosslinked (XLPE / XLPO), double layer |
Service temperature | Around −40 °C to +90 °C; short-circuit up to +120 °C |
Weathering | UV, ozone and weather resistant |
Fire behavior | Flame-retardant per the PV cable requirement |
Exact values depend on the manufacturer's construction and the applicable edition of the standard — always check the cable datasheet and certificate for your specific cross-section and order.
IEC 62930 vs EN 50618 (H1Z2Z2-K) vs PV1-F
All three describe the same physical cable idea. The differences are the standard body and the exact DC voltage rating:
Standard / model | Body | DC rating | Conductor | Structure |
|---|---|---|---|---|
IEC 62930 | International (IEC) | 1.5 kV | Tinned copper, Class 5 | XLPE/XLPO double insulation |
EN 50618 (H1Z2Z2-K) | European (CENELEC) | 1.5 kV | Tinned copper, Class 5 | XLPE/XLPO double insulation |
2 PfG 1169 (PV1-F) | TÜV specification | 1.8 kV | Tinned copper, Class 5 | XLPE/XLPO double insulation |

Where IEC 62930 Cable Is Used
Module string cabling — between PV modules.
Module → combiner box — string collection.
Combiner / array → inverter DC input — the DC side of the inverter.
Any fixed outdoor DC PV wiring where a 1.5 kV DC, UV-resistant double-insulated cable is required.
HuaCable IEC 62930 Cable
HuaCable's IEC 62930 PV DC cable is TÜV certified and built to the construction above — flexible tinned-copper conductor, XLPE/XLPO double insulation, black UV-resistant sheath. Common cross-sections run 1.5–6 mm², supplied alongside matched MC4 connectors (CE). For the European CE route, our H1Z2Z2-K (EN 50618, TÜV + CE) covers the same application with CE marking.
FAQ
What is IEC 62930?
IEC 62930:2017 is the international standard for single-core, flexible photovoltaic DC cables used in PV systems. It defines the conductor, insulation, sheath, voltage rating and outdoor-performance requirements for cables that connect solar modules, combiner boxes and inverters on the DC side.
What conductor does IEC 62930 use — copper or aluminium?
IEC 62930 specifies a copper conductor, flexible Class 5, normally tinned. Aluminium conductor PV cables are not covered by IEC 62930.
What voltage rating is IEC 62930 PV cable?
IEC 62930 PV DC cable is rated 1.5 kV DC (U0/U = 1.5/1.5 kV). This is the same DC voltage class as EN 50618 (H1Z2Z2-K); PV1-F under 2 PfG 1169 is rated slightly higher at 1.8 kV DC.
How does IEC 62930 compare with EN 50618 and PV1-F?
All three define the same physical cable idea — flexible tinned-copper conductor with crosslinked (XLPE/XLPO) double insulation for outdoor DC solar use. IEC 62930 is the international spec (1.5 kV), EN 50618 is the European spec for H1Z2Z2-K (1.5 kV), and 2 PfG 1169 is the TÜV spec for PV1-F (1.8 kV). The main differences are the standard body and the exact DC voltage rating.
Is IEC 62930 cable from HuaCable CE certified?
HuaCable's IEC 62930 PV cable is TÜV certified. It is not claimed as CE certified — CE applies to our H1Z2Z2-K (EN 50618) cable. Always confirm the exact certificate for your model and market.
Engineer's Conclusion
IEC 62930:2017 is the international rulebook for the PV DC cable: flexible tinned-copper conductor, crosslinked double insulation, 1.5 kV DC, built for 25-year outdoor life. It sits alongside EN 50618 (H1Z2Z2-K) and 2 PfG 1169 (PV1-F) as three faces of the same cable family — pick by market and certification need. Remember the key boundary: IEC 62930 DC solar cable is copper; aluminium belongs to a different, AC/MV application outside this standard.
