S CONN MAXIMUM CONNECTIVITY PV4 Extension Cable Set, 4mm², 2x 25m, Black 02-32105

Extending photovoltaic panel connections over long distances requires a reliable, weather-resistant cable that maintains high DC voltage and current without degradation. The S CONN MAXIMUM CONNECTIVITY PV4 Extension Cable Set provides two 25-meter, 4 mm² solar cables with pre-assembled MC4-compatible connectors, enabling safe and efficient linking of solar modules to inverters or combiner boxes.

Who is it for

Solar installers and system integrators needing a durable, ready-to-use extension for PV arrays, especially in residential or commercial installations where panel strings are far from the inverter.

Main features

• Set includes two 25 m cables, each with one male and one female MC4-compatible connector for series or parallel connections.
• 4 mm² tinned copper conductor supports up to 30 A at 1500 V DC, minimizing voltage drop over long runs.
• UV-resistant, halogen-free XLPE insulation and jacket withstand harsh outdoor conditions from -40°C to +90°C.
• IP67 mated connector rating ensures protection against dust and temporary immersion.
• Flame-retardant design meets IEC 60332-1-2 for added safety.
