Product Overview
The PV1-F reference construction, still written into tenders
The PV1-F 2.5mm² is a single-core flexible photovoltaic cable designated to TÜV 2PfG 1169/08.2007, the TÜV specification for PV module connection cables. It is the cable that links module to module, runs along the string, enters the DC combiner box and continues to the inverter. The same construction is also available under the EN 50618 / IEC 62930 H1Z2Z2-K designation where a project specifies the European standard instead.
The conductor is Class 5 flexible stranded tinned copper to IEC 60228. Tinning keeps the strand surface stable in humid, coastal and polluted conditions, while the fine stranding makes the cable easy to route around module frames and into junction boxes. The 2.5mm² size carries 41 A in free air at 60°C ambient and its maximum DC resistance is 8.21 Ω/km at 20°C, giving a loop voltage drop of about 16.42 V/A/km.
Insulation and sheath are both electron-beam cross-linked XLPO, halogen-free and low smoke, tested to IEC 60754-1 and -2 for halogen acid gas and to IEC 61034 for smoke density with light transmittance above 70%. The cross-linked structure supports a +120°C conductor temperature for up to 20 000 hours and a permanent 90°C rating on the 30-year IEC 60216 basis.
Rated 0.6/1.0 kV AC and 0.9/1.8 kV DC, the cable covers 1500V DC string architectures, and it is tested at 6.5 kV AC or 15 kV DC for 5 minutes. It is specified from −40°C to +90°C ambient, withstands 1 000 hours of damp heat at 90°C and 85% relative humidity, and it is designed for cable tray, conduit and free-air installation. A buried run needs additional mechanical protection and a higher water rating, agreed for the construction ordered and checked against your local regulations.

Key Features
Eight features that matter on a PV site
TÜV 2PfG 1169 — PV1-F
Designated PV1-F to the TÜV 2PfG 1169/08.2007 specification for photovoltaic module connection cables; EN 50618 / IEC 62930 available as an alternative designation.
Tinned Copper Conductor
Class 5 flexible stranded tinned copper to IEC 60228 — flexible routing plus a corrosion-resistant strand surface, with a maximum DC resistance of 8.21 Ω/km at 20°C for 2.5mm².
Electron-Beam XLPO
Insulation and sheath are cross-linked by electron beam, giving a thermally and mechanically stable compound rather than a thermoplastic jacket.
0.6/1.0 kV AC · 1.8 kV DC
Rated 600/1000 V AC and 900/1800 V DC maximum permissible operating voltage, proof-tested at 6.5 kV AC or 15 kV DC for 5 minutes — matched to 1500V DC string architectures.
Halogen-Free & Low Smoke
IEC 60754-1 for halogen content, IEC 60754-2 for corrosive gases, IEC 61034 for smoke density with light transmittance above 70%.
120°C for 20 000 Hours
+120°C conductor operating temperature per IEC 60216 for up to 20 000 hours, a permanent 90°C rating on the 30-year basis, and +200°C for a maximum of 5 seconds under short circuit.
UV, Ozone & Damp Heat
UV tested to ISO 4892-2 method A and UL 1581, ozone resistance to EN 50396 test type B, and 1 000 hours of damp heat at 90°C and 85% relative humidity.
4 × OD Bends, Tray or Conduit
The published minimum bending radius is 4 × overall diameter, so the cable can follow tight module and conduit routes.

The 2.5 mm² row is highlighted — it is the size this page covers; sizes from 1.5 mm² to 35 mm² are produced on the same construction, with larger sizes to order. Dimensions and weights are the published nominal figures for cable to TÜV 2PfG 1169 and are subject to manufacturing tolerance; the values stated on the order confirmation take precedence. Current ratings are a single cable in free air at 60°C ambient and must be derated for higher ambient temperature, grouping, enclosure and other installation conditions — our engineers confirm the figure for your installation method. Maximum DC resistance values are the IEC 60228 Class 5 tinned-copper limits.

FAQ
Questions buyers ask before ordering
PV1-F is the cable designation used in the TÜV 2PfG 1169 specification for photovoltaic module connection cables. H1Z2Z2-K is the designation used in EN 50618, the European standard for cables in photovoltaic systems, and in its IEC equivalent IEC 62930. Both describe a single-core, flexible, halogen-free DC photovoltaic cable, but the published ratings differ: PV1-F is rated 600/1000 V AC and 900/1800 V DC with a +200°C short-circuit limit, while EN 50618 rates the cable 1.0/1.0 kV AC and 1.5/1.5 kV DC with +250°C. SORIVO supplies this construction as PV1-F to TÜV 2PfG 1169, and the same construction is available under the H1Z2Z2-K designation for EN 50618 projects. Tell us which designation your specification names and we will quote the matching documentation.
Yes. The maximum permissible operating voltage in DC systems is 0.9/1.8 kV DC, and the AC rating is 0.6/1.0 kV with 0.7/1.2 kV maximum permissible. That covers 1500V DC photovoltaic strings, which is the architecture this cable is normally specified into. The finished cable is proof-tested at 6.5 kV AC or 15 kV DC for 5 minutes — the standard specifies these as alternative tests, not two tests applied together. Final selection, including any derating for ambient temperature, remains the responsibility of the system designer.
2.5mm² carries 41 A in free air at 60°C ambient with a maximum DC resistance of 8.21 Ω/km at 20°C; 4mm² carries 55 A at 5.09 Ω/km. 2.5mm² is usually chosen for short module jumpers and smaller residential strings, while 4mm² is the size normally specified for MC4 terminations and for longer string runs. For long string runs the deciding factor is usually voltage drop rather than ampacity: 2.5mm² drops about 16.42 V/A/km for the complete loop, so a longer run at the same current loses more. Send us the string current and the one-way run length and we will confirm the size.
+120°C is permitted for a total of 20 000 hours of operation per IEC 60216, and 90°C continuous conductor temperature is the basis of the 30-year service life. Under short-circuit conditions the conductor may reach +200°C for a maximum of 5 seconds as specified in TÜV 2PfG 1169; for constructions that are also qualified to EN 50618 the figure is +250°C. The ambient range for both fixed and flexible installation is −40°C to +90°C.
Outdoors, yes — the halogen-free XLPO insulation and sheath are UV tested to ISO 4892-2 method A and UL 1581, ozone resistant to EN 50396 test type B, and rated for 1 000 hours of damp heat at 90°C and 85% relative humidity. On burial we would not treat the standard PV1-F construction as a direct-burial cable — a buried run needs additional mechanical protection and a higher water rating, agreed for the construction ordered. The construction also meets the long-term DC-stability requirement of the specification — 240 h at 85°C in 3% salt water at 0.9 kV DC, Annex D of TÜV 2 PfG 1169. Whether a buried run needs sand bedding, warning tape or additional mechanical protection depends on your local wiring regulations, and cable selection stays with the installation designer.
2.5mm² sits below the wire range of the standard MC4 sizes: our MC4-compatible connectors are rated for 4 mm² and 6 mm² (AWG 10–12), and the great majority of MC4, MC4-Evo 2, Stäubli and Amphenol H4 bodies are offered in those two sizes. This construction has an overall diameter of 4.7 – 5.1 mm and a maximum conductor diameter of 1.9 mm. 2.5mm² is normally used for short module jumpers and smaller residential strings rather than for connectorised string runs — if your design needs a 2.5mm² termination, tell us and we will confirm which connector body accepts it before quoting. We also supply MC4-compatible connectors and pre-terminated harnesses.
PV1-F is a photovoltaic cable intended for the DC side of a PV array. For battery racks, battery containers and PCS connections the dedicated product is our 1500V ESS Energy Storage Cable, which is designed around the TÜV 2 PfG 2693 requirements for cables connected to battery energy storage systems, with a +125°C conductor rating. If your project combines PV and storage, we can quote both constructions together and confirm which cable belongs on each DC segment.
Yes to both. Certificate and test documentation is provided with the quotation and with the shipment, and the exact scope is always confirmed against the certificate for the selected construction before the order is placed. SORIVO can also arrange sample orders for qualification and project evaluation; availability and lead time depend on cross-section, colour and current stock. Standard stocked sizes may be available within a few working days, while customised constructions require additional production time.
