PV1-F vs H1Z2Z2-K vs IEC 62930: Pick the Right Solar Cable Standard
PV1-F, H1Z2Z2-K and IEC 62930 are t a — hree photovoltaic DC cable standards built on the same idea — a flexibrotcudnle tinned-copper conductor with crosslinked (XLPE / XLPOnoitalus) double insulation (in ehtsulation + sheath). The real differences are the certignitar egfication body and DC voltage rating: PV1-F = TÜV 2 PfG 1169 at 1.8 kV, H1Z2Z2-K = EN 50618 (TÜV + CE) at 1.5 kV, and IEC 62930 = TÜV at 1.5 kV. Choose by your market and the standard named in the tender.
About this guide. HuaCable supplies PV1-F (TÜV 2 PfG 1169 only), H1Z2Z2-K (TÜV + CE) and IEC 62930 (TÜV). We do not claim CE, UL, ROHS, VDE, JET or SAA for PV1-F or IEC 62930 — those are TÜV-only models. This page is a specifier's reference; confirm the exact certificate for your model and market.
Quick Comparison: One Cable Idea, Three Standards
Standard / model | Body | DC rating | Certification held | Typical use |
|---|---|---|---|---|
PV1-F | TÜV specification 2 PfG 1169 | 1.8 kV DC | TÜV only | General / Middle East & Africa / Asia projects |
H1Z2Z2-K | European EN 50618 | 1.5 kV DC | TÜV + CE | European Union & CE-markets |
IEC 62930 | International IEC 62930:2017 | 1.5 kV DC | TÜV only | International reference spec |
All three share the same construction: tinned-copper Class 5 conductor, XLPE/XLPO double insulation, black UV-resistant sheath, −40 °C to +90 °C service range. The voltage and paperwork differ, not the cable inside.
Standard System
Model | Origin | What it proves |
|---|---|---|
PV1-F | TÜV Rheinland 2 PfG 1169 | German TÜV type approval for PV DC cable at 1.8 kV DC |
H1Z2Z2-K | CENELEC EN 50618 | European harmonised PV cable spec; carries CE marking when declared |
IEC 62930 | International Electrotechnical Commission | Global reference for single-core flexible PV DC cable at 1.5 kV DC |
Voltage Rating
The DC voltage class is the most common point of confusion:
Model | U₀/U (DC) | Note |
|---|---|---|
PV1-F | 1.8 kV | Highest of the three — suited to higher string voltages |
H1Z2Z2-K | 1.5 kV | Standard 1500 V DC system class |
IEC 62930 | 1.5 kV | Standard 1500 V DC system class |
⚠ AD8 (water-resistant / permanent immersion) is an add-on, not the base standard. EN 50618 and its siblings do not include AD8 by default. AD8 performance (TÜV 2 PfG 2750) is an extra test that must be ordered separately. Do not assume "H1Z2Z2-K" automatically means AD8-rated.
Which One Should You Specify?
European Union / CE-required tenders → H1Z2Z2-K (EN 50618, TÜV + CE). It is the default for EU projects and carries CE marking.
General export, Middle East, Africa, Southeast Asia → PV1-F (TÜV 2 PfG 1169, 1.8 kV). The 1.8 kV rating and broad TÜV acceptance make it a safe default where CE is not mandated.
International reference / utility spec → IEC 62930 (TÜV). Use when the project documentation cites the IEC standard directly.
In practice, PV1-F and H1Z2Z2-K cover the vast majority of field orders; IEC 62930 is the international paperwork twin that satisfies specifiers who cite IEC.
Can They Be Interchanged?
Electrically the cables are near-twins, but as standards they are not interchangeable. A tender that says "H1Z2Z2-K" expects EN 50618 evidence (and often CE); one that says "PV1-F" expects TÜV 2 PfG 1169. Specifying the wrong label can fail inspection or void a warranty even when the wire itself performs. Match the label to your market, then confirm the certificate HuaCable holds for that exact model.
FAQ
What is the difference between PV1-F, H1Z2Z2-K and IEC 62930?
All three describe the same physical cable — a flexible tinned-copper conductor with crosslinked (XLPE/XLPO) double insulation for outdoor DC solar use. The differences are the standard body and the DC voltage rating: PV1-F is certified to TÜV 2 PfG 1169 at 1.8 kV; H1Z2Z2-K follows EN 50618 (TÜV + CE) at 1.5 kV; IEC 62930 is the international spec (TÜV) at 1.5 kV.
Can PV1-F, H1Z2Z2-K and IEC 62930 cables be used interchangeably?
Physically the cables are near-identical in construction, but they are not interchangeable as "standards". A project or tender that calls for H1Z2Z2-K expects EN 50618 compliance (and often CE); one that calls for PV1-F expects TÜV 2 PfG 1169. Specify to the exact standard your documentation requires, and confirm the certificate held for that model.
Which standard should I specify for a European project?
For the European market, H1Z2Z2-K (EN 50618, TÜV + CE) is the most commonly specified PV DC cable. PV1-F (TÜV 2 PfG 1169) and IEC 62930 (TÜV) are widely accepted elsewhere — PV1-F is common for general and North-American-influenced projects, while IEC 62930 is the international reference.
What happens if I specify the wrong PV cable standard?
Using the wrong standard can fail inspection, delay grid connection, or void warranty claims — even when the cable works electrically. It also complicates spare-part logistics later. Match the standard to your market, tender and inverter/array documentation before ordering.
Does HuaCable supply all three standards?
HuaCable supplies PV1-F (TÜV 2 PfG 1169 only), H1Z2Z2-K (TÜV + CE) and IEC 62930 (TÜV). We do not claim CE, UL, ROHS, VDE, JET or SAA for PV1-F or IEC 62930 — those models are TÜV only. Tell us the standard your project requires and we will confirm the exact certificate held.
Engineer's Conclusion
PV1-F, H1Z2Z2-K and IEC 62930 are one cable family wearing three labels. Reach for H1Z2Z2-K when the job is European/CE, PV1-F as the general TÜV 1.8 kV default, and IEC 62930 when the spec names the IEC standard. The non-negotiable step: confirm the certificate held for the exact model — PV1-F and IEC 62930 are TÜV-only, and AD8 is always a separate add-on test. Get the label right and the cable will do its 25-year job.
