Requirements for the PV cables

The following requirements apply only to the PV+ and PV- cables. For grounding conductor, note that the requirements are different.

• Conductor type: copper wire

• Maximum cable length within the inverter: 180 mm (7.1 in)

• Conductor cross-section: 2 mm² to 6 mm²

• External diameter: 5 mm to 8 mm

• Nominal voltage: at least 600 V

• Insulation stripping length: 12 mm

• The cables must be designed according to the local and national guidelines for the dimensioning of lines.
