Solar cable red 75m 6mm² IEC62930 – SOLR675 for professional PV projects

The solar cable SOLR675 (75 metres, 6mm²) in red is the high-performance solution for photovoltaic installations that have to efficiently cope with long distances and high currents. With a length of 75 metres and a reinforced cross-section of 6mm², this cable offers maximum reserves for string cabling on extensive roofs or the connection of module fields to inverters located far away. The red colouring serves to mark the positive pole (+) in accordance with standards.

Certified according to international standard IEC 62930, the SOLR675 meets the most stringent quality requirements for permanent use under extreme conditions. The generous cross-section ensures that the voltage drop is minimised even over long cable runs, which directly results in a higher overall yield from your solar installation.

Highlights at a glance

• High efficiency: The cross-section of 6mm² massively minimises the electrical resistance, which is particularly decisive for efficiency over the distance of 75 metres.
• Certified safety: Complies with IEC 62930 (H1Z2Z2-K) standard for permanent use in photovoltaic direct current systems up to 1500V.
• Optimum project length: 75 metres in one piece enable continuous installation over long distances without unnecessary joints or additional plug connections.
• Extremely resistant: The high-quality XLPO double insulation protects the cable from embrittlement due to intense UV radiation, ozone and weathering for decades.
• Corrosion-protected conductor: Fine-stranded, tinned copper offers consistently excellent conductivity and effective protection against oxidation, even in humid or salty air.
• Wide temperature range: Safe operation under the most adverse climatic conditions from -40°C to +90°C.

Areas of application

SOLR675 is the ideal choice for demanding long-distance connections:

• Large roof systems & commercial buildings
  • Perfect for the connection of solar modules to the inverter when it is installed over several floors or in a distant technical room.
• Open space & garden systems
  • Ideal for connecting distant module fields to the feed-in point with minimal losses.
• High-performance stand-alone systems
  • Ideally suited for 24V or 48V systems with high charging currents, where every volt retention at the battery counts.

Installation & safety notes

• Professional assembly
  • Use only high-quality MC4 connectors that are approved for 6mm² cross-sections to complete the cable. Gas-tight crimping is essential for long-term safety.
• Protection when laid underground
  • Although the cable is weather-resistant, it must always be run in a suitable protective conduit when laid underground to protect it from mechanical influences.
• Parallel cable routing
  • Route positive (red) and negative (black) cables as closely together as possible to minimise electromagnetic interference fields and induction loops.

FAQs about the solar cable red 75m 6mm²

Why is 6mm² almost always the better choice for 75 metres in length?

To keep power losses in check. Over a total length of 150 metres (supply and return), the resistance adds up considerably. A 6mm² cable reduces the voltage drop by around a third compared to 4mm², which means a noticeable increase in yield over the lifetime of the system.

Can the cable also be laid indoors?

Yes. Thanks to its flame-resistant and halogen-free XLPO insulation, the SOLR675 can be safely laid in buildings to route the energy from the roof to the inverter room.

Does the cable fit into standard MC4 plugs?
