Australia Market — Solar BOS / PV Cables
PV Cable Supplier
for Australia
H1Z2Z2-K single-core DC solar cable — 4mm² to 16mm², 1000V and 1500V DC, IEC 62930 / EN 50618 certified. 90°C conductor rating and UV Class A sheath for Australian rooftop conditions. AS/NZS 5033 compliance documentation supplied. ChAFTA 0% import duty.
H1Z2Z2-K PV Cable for Australian Projects
Australian residential rooftops, commercial Klip-Lok roofing, and utility-scale ground-mount arrays all share a common PV cable requirement: single-core DC cable rated for sustained outdoor UV exposure and high operating temperatures. H1Z2Z2-K conforming to IEC 62930 is the international standard that addresses these requirements and is widely accepted on CEC-accredited Australian installations under AS/NZS 5033.
The Australian market is predominantly 1000V DC at the residential level, with 1500V DC increasingly adopted for large C&I rooftops and utility ground-mount projects. OmniSol supplies both voltage classes in 4mm², 6mm², 10mm², and 16mm² conductor sizes. Red (positive) and black (negative) rolls in standard drum lengths, with custom cut lengths available for larger project orders.
Cable ships consolidated in the same 40HQ container as mounting hardware, MC4 connectors, DC protection devices and combiner boxes — a single shipment, one Australian Border Force declaration, one ChAFTA Form E covering all BOS categories. Transit time from Xiamen is approximately 15–22 days depending on destination port.
H1Z2Z2-K Specifications — Australian Project Sizes
Current capacity at 30°C ambient (IEC base) and estimated at 45°C outdoor ambient (Australian summer, open-air installation). Derating factor ≈ 0.79 at 45°C per IEC 60364-5-52 Table B.52.14.
| Cross-section | Voltage rating | Current @ 30°C | Current @ 45°C (est.) | Typical AU use case |
|---|---|---|---|---|
| 4mm² | 1000V DC | 41A | ~32A | Residential rooftop, string runs ≤30m (1000V) |
| 6mm² | 1000V & 1500V DC | 54A | ~43A | C&I rooftop, runs 30–60m; entry-level 1500V utility |
| 10mm² | 1000V & 1500V DC | 73A | ~58A | 1500V utility-scale, long string runs >60m |
| 16mm² | 1000V & 1500V DC | 96A | ~76A | Array home-run cables, combiner box output |
Exact derating depends on installation method (open air vs. conduit vs. cable tray) and roof surface type. Verify with voltage drop calculator before ordering.
Australian-Specific Cable Considerations
UV index 10–12 in northern Australia
Darwin, Cairns, Broome and northern WA record UV index levels of 11–12+ at peak summer. H1Z2Z2-K's cross-linked polyolefin outer sheath provides IEC 62930 UV Class A resistance — rated for 30-year service life under sustained high-UV exposure. Standard PVC-insulated cable is not acceptable for outdoor solar cable runs in Australian conditions.
Roof surface derating: Colorbond and Klip-Lok
Dark-coloured Colorbond and Klip-Lok metal roofing in direct Australian sun reaches surface temperatures of 70–80°C. Cable laid directly on these surfaces requires derating from the IEC 60364-5-52 base current values. For Klip-Lok installations, cable is typically clipped to the underside of rails; for corrugated iron, cable runs along rail channels. Always specify installation method in your RFQ so correct derating is applied.
AS/NZS 5033 compliance documentation
CEC-accredited installers are required to maintain documentation that the installed PV array meets AS/NZS 5033. For cable, the relevant evidence is an IEC 62930 type approval certificate and third-party test report confirming UV resistance, conductor temperature rating, and current capacity. OmniSol provides these documents with every cable order at no additional cost.
MC4 connector brand matching
CEC guidelines and IEC 62852 require that MC4-compatible connectors from different manufacturers be cross-compatibility certified before mating. Do not mix connector brands (e.g. Stäubli with a non-certified compatible) unless the manufacturers have published a compatibility declaration. When ordering cable and connectors together, specify the connector brand so OmniSol can confirm compatibility.

PV Cable Voltage Drop Calculator
Enter string length, short-circuit current, conductor size and system voltage. The calculator checks voltage drop against the AS/NZS 5033 recommendation of <1% for string wiring and <3% total system. Australian temperature derating is applied automatically.

Frequently Asked Questions
What PV cable standard is required for Australian solar installations?
AS/NZS 5033:2021 requires PV array wiring to use cables suitable for outdoor UV exposure with appropriate current-carrying capacity. H1Z2Z2-K conforming to IEC 62930 (or its European equivalent EN 50618) is the accepted single-core DC solar cable standard. It is UV-resistant, rated to 90°C conductor temperature, and designed for the direct-sunlight, high-temperature conditions found on Australian rooftops. The CEC Approved Products List does not cover cable directly; IEC 62930 test reports are the accepted compliance evidence for AS/NZS 5033.
What conductor sizes are available for Australian residential and C&I projects?
OmniSol supplies H1Z2Z2-K in 4mm², 6mm², 10mm², and 16mm² conductor cross-sections. For Australian residential rooftop systems (1000V DC, string runs typically 15–30m), 4mm² is standard. For larger C&I systems at 1000V with longer runs, 6mm² reduces voltage drop below the AS/NZS 5033 recommended 1%. For 1500V DC utility-scale systems, 6mm² or 10mm² is typical depending on string length and Isc. Use the PV cable voltage drop calculator to confirm sizing before ordering.
How does Australian roof temperature affect PV cable selection?
In QLD, WA, NT and northern SA, summer ambient temperatures regularly reach 40–45°C. Rooftop cable installed on dark metal Colorbond or Klip-Lok surfaces in direct sun can experience surface temperatures above 70°C. IEC 60364-5-52 base current ratings assume 30°C ambient; at 45°C a derating factor of approximately 0.79 applies. H1Z2Z2-K's 90°C conductor rating provides adequate headroom for Australian conditions without excessive cross-section upsizing when correct installation method derating is applied.
Do I need specific cable for off-grid and SAPS installations in WA or NT?
Stand-alone power systems (SAPS) in WA, NT and remote QLD follow the same cable standards as grid-connected systems under AS/NZS 5033 and AS/NZS 3000. H1Z2Z2-K is suitable for both grid-connected and off-grid DC wiring. For remote SAPS where maintenance access is limited, the 90°C rating and UV-resistant sheath of H1Z2Z2-K are particularly important for long-term reliability in harsh outback conditions.
Can PV cable ship in the same container as mounting hardware and BOS accessories?
Yes. PV cable (non-hazardous, no dangerous goods classification) ships unrestricted alongside mounting hardware, MC4 connectors, DC protection devices and combiner boxes in the same 20ft or 40ft HQ container. OmniSol's standard Australia mixed-BOS container service consolidates all categories, reducing freight cost and simplifying Australian Border Force clearance to a single declaration. Cable drums are floor-loaded or palletised alongside mounting hardware.
