4mm2 PV1-F Solar Cable 1000V DC TUV Photovoltaic Wire For Solar Panels
Product Description
This PV1-F 4mm² solar cable delivers a fixed connection between photovoltaic panels and combiner boxes, inverters, or DC distribution equipment. Rated at 1000V DC, it supports residential and commercial solar arrays. TUV certification guarantees compliance with EN 50618 standards.
The tinned copper conductor (Class 5 flexible) resists corrosion – a common failure point in outdoor DC circuits. Cross-linked polyethylene (XLPE) insulation provides low smoke, halogen-free performance during a fire. Temperature range: -40°C to +90°C. Peak resistance up to 120°C.
Key Features
4mm² cross section – supports up to 55A current capacity (depending on ambient temperature).
1000V DC rating – matches most string inverters and combiner boxes for ground-mount or rooftop arrays.
TUV EN50618 approved – each reel carries a traceable TUV mark.
UV resistant and waterproof – rated for direct burial and exposed outdoor runs (IP68).
Flexible – bending radius 5×OD, easy to route through conduits or cable trays.
