PV1-F 1.5kV DC Solar PV String Cable
PV1-F is the reference DC string cable for photovoltaic interconnection. Tinned-copper conductor (long-term corrosion immunity), double-insulated halogen-free polyolefin, rated 1500V DC for modern utility-scale systems. TUV 2 PfG 1169 certified — the qualification SEA utilities accept for grid-tie solar.

Overview
Class 5 fine-stranded tinned-copper conductor; cross-linked polyolefin (XLPO) primary insulation; second cross-linked polyolefin outer sheath; halogen-free, low-smoke, UV-stabilized for 25-year outdoor exposure. The double-insulation construction allows installation under standard PV system rules without separate conduit. Tinned conductor resists the moisture and humidity that corrode bare copper at module-junction-box connections.
Key Features
TÜV-certified PV1-F
Tested by TUV Rheinland against PV1-F qualification — the certification SEA utilities accept for grid-tie solar plants.
1500V DC system rated
Sized for the higher-voltage DC systems standard in modern utility-scale solar — fewer strings, lower balance-of-system cost.
Tinned-copper conductor
Tin coating resists the moisture corrosion that bare-copper conductors suffer at module junction-box connections over decades.
Applications
PV string cabling
Module-to-module and string-to-combiner DC cabling on rooftop and ground-mount plants.
Combiner-to-inverter trunks
DC trunk runs from combiner boxes to central inverters in utility-scale plants.
