Solar PV cable extra digital 4 mm², 100 m, red

Solar PV cable extra digital 4 mm², 100 m, red is a single-core photovoltaic cable (model NV820412) designed for DC wiring in solar power systems. With a 4 mm² oxygen-free copper conductor and 100 m length, this red cable is intended for connecting modules, inverters and junction boxes, offering low resistance and stable conductivity for outdoor and indoor installations when used with appropriate conduits and connectors.

Advantages

The cable features an oxygen-free copper core with standard high-quality PVC insulation, providing low electrical resistance, good conductivity and mechanical flexibility. It is flame-retardant, waterproof and resistant to a wide temperature range (-45°C to +120°C), as well as to acids, alkalis and ultraviolet exposure. Rated for 1500 V and certified to TUV and CE standards, it supports short-circuit temperatures up to 200°C for brief periods.

Suitable for

• DC wiring between solar panels and inverters
• Connections to junction boxes and combiner boxes
• Outdoor solar PV installations when routed through conduits or protected channels
• Low-voltage power transfer within photovoltaic arrays

How to use

Route the cable according to local electrical codes and solar installation guidelines. Use appropriate solar-rated connectors and terminals, ensure correct polarity when connecting modules and inverters, and install the cable in conduits or protected trays for outdoor exposure. Avoid sharp bends and mechanical stress on terminations; strip insulation to the correct length for crimping or terminal connections and secure all joints with approved connectors.

Usage recommendations

For long-term outdoor performance, combine this PV cable with UV-resistant conduits and compatible MC4 or other solar-rated connectors, inspect connections periodically, and follow manufacturer and local regulations for earthing and overcurrent protection.
