PV String Wire – Engineered for Demanding Solar DC Applications

For string-level PV installers, GERITEL WIRE focuses this product page on string wiring, giving buyers a clear cable option for module-to-module and string-to-combiner connections. For customers using the terms solar module cable and PV interconnection cable, the product combines flexible handling with an outdoor-oriented construction suitable for photovoltaic DC wiring. Fine-stranded tinned copper forms the flexible conductor, protected by cross-linked halogen-free insulation and a weather-ready outer sheath for photovoltaic DC service. It is engineered for modern high-voltage PV DC circuits, with strong thermal performance plus resistance to sunlight, ozone, humidity and changing weather conditions. Buyers can work with GERITEL WIRE on marking, packaging, technical clarification and export documentation for practical order execution.

FAQ

Can I connect a 6mm² extension to a 4mm² panel lead?

A 6mm² to 4mm² solar cable transition can be acceptable if the 4mm² section is itself adequately rated and the connector/termination is designed for the actual conductor sizes. The smallest section remains the limiting part of the circuit. For distributors and EPC buyers, GERITEL WIRE can provide specification confirmation, project packaging and documentation support.

How far can I run 4mm² PV cable?

There is no fixed 4mm² PV cable distance because allowable length depends on string current, system voltage and target voltage drop. Calculate the complete DC loop instead of using a distance rule without electrical data. GERITEL WIRE focuses on matching the ordered construction to the applicable certificate and can provide supporting technical documents for project review.

How far can I run 6mm² PV cable?

6mm² PV cable distance depends on operating current, system voltage and acceptable voltage drop. A longer route usually favors 6mm² over 4mm², but the design should be calculated rather than guessed. GERITEL WIRE can assist with OEM marking and packaging while keeping the electrical construction aligned with the approved product specification.

What information do you need to recommend a solar cable size?

For a solar cable size calculation, provide system DC voltage, string current/Isc, one-way route length, installation method, ambient temperature, grouping, preferred voltage-drop limit and connector/terminal constraints. GERITEL WIRE can help confirm the requested standard, size, color and marking before quotation so the cable matches the project specification.
