⚙How It Works
PV1-F cable carries the DC current from the modules to the inverter. Its double insulation and electron-beam cross-linked sheath give it a 1500 V DC rating and decades of UV and weather resistance outdoors, while its flexible tinned-copper conductor resists corrosion at the connector terminations. Correctly sizing the cross-section keeps voltage drop and resistive loss within design limits over the full run length.
▦Structure & Composition
The cable has a tinned-copper conductor, a cross-linked polyethylene (XLPE) insulation layer and a double-insulated outer sheath, all rated for 1500 V DC and continuous outdoor exposure from -40 to +90 °C. It is sold by cross-section (4, 6, 10 mm²) to match the string current, with flame-retardant and halogen-free options for indoor or high-safety installations.

Applications
Selection Guide
- Size the cross-section so voltage drop stays within about 1–2 % at the string's maximum current.
- Choose halogen-free cable for indoor runs and flame-retardant for high-safety sites.
- Match the cable to the MC4 connector's accepted conductor range for a reliable, watertight joint.
Frequently Asked Questions
Why PV1-F over ordinary building wire?
PV1-F is double-insulated, UV-resistant and rated for 1500 V DC continuous outdoor use, unlike general building wire.
How do I size the cross-section?
Keep voltage drop within 1–2 % at maximum string current, accounting for cable length and ambient temperature.
What temperature range does it handle?
The cable operates from -40 to +90 °C, covering desert and alpine installations alike.
