What this cable is for

6 mm² PV1‑F wire handles higher current than 4 mm² – suitable for longer strings, combiner box feeders, or inverters with 60A+ input. Rated at 1500V DC, it works in large commercial and utility‑scale solar farms where system voltage exceeds 1000V.

The XLPE insulation stays flexible down to -40°C and resists cracking under repeated bending. Tinned copper conductor prevents galvanic corrosion when paired with aluminum lugs or MC4 connectors in outdoor environments.

Key points installers check

• 1500V DC rated – fully compatible with modern high‑voltage string inverters (Sungrow, Huawei, SMA).

• 6 mm² carries 70A – reduces voltage drop over long runs (e.g., 100m string).

• Single core – available in black or red for polarity identification.

• TUV certified – traceable certificate per EN50618.

• No halogen – low smoke, non‑toxic fumes in fire per IEC 61034.

Typical applications

• String wiring for 1500V DC systems (up to 30 panels in series)

• Feeder cables from combiner box to DC distribution cabinet

• Single‑core replacement for damaged array wiring

• Off‑grid battery banks (charging circuits with 60A+ current)

Not for AC secondary wiring inside buildings.

FAQ

Q: Can I use 6 mm² PV1‑F with MC4 connectors?
Yes. Most 1500V rated MC4 connectors accept 4–6 mm² cable. Use a crimping tool with the correct die (2.5–6 mm²).

Q: Difference between PV1‑F and H1Z2Z2‑K for 6 mm²?
H1Z2Z2‑K has double insulation and higher abrasion resistance. For 1500V systems, both pass EN50618. PV1‑F is lighter and slightly cheaper.

Q: What’s the maximum string length for 6 mm² at 1500V?
At 70A and 2% voltage drop – roughly 80 meters (one way) for copper. Run your own calc using ambient temperature and local code.

Q: Is the conductor pure copper?
Yes. Tinned electrolytic copper (99.99%). 

Q: Can I bury this cable directly?
Yes, if rated IP68 and protected from mechanical damage. Use conduit in rocky soil.
