Feature Product

Solar Cable 4mm² & 6mm² – TUV-Certified PV Wire for Solar Panels (DC 1.5kV, UV Resistant)

Short Description:
Our solar cable exceeds IEC 62930 standards, engineered for 25+ years of peak performance in photovoltaic installations. Featuring tinned copper conductors and double-layered XLPO insulation, it withstands extreme UV exposure (-40°C to 120°C) and 1.5kV DC voltage. Halogen-free and flame-retardant (LSZH) for enhanced safety. Ideal for panel-to-inverter connections in rooftop arrays, solar farms, and battery storage.

Product Description
Our solar cable is engineered for photovoltaic systems, offering superior UV resistance, DC voltage stability, and 25+ year lifespan – exceeding IEC 62930 standards. Unlike generic cables, this PV wire features tinned copper conductors and cross-linked polyolefin insulation to prevent degradation in extreme temperatures (-40°C to 120°C). Ideal for connecting solar panels, inverters, and combiner boxes in commercial/utility-scale installations.
