Requirements for the PV cables

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

• The cables must be made of copper.

• Maximum cable length within the inverter: 180 mm

• Conductor cross-section: 2.5 mm² to 10 mm² (14 AWG to 8 AWG)

• Cable diameter: 5 mm to 8 mm (0.2 in to 0.3 in)

• Nominal voltage: at least 600 V

• Insulation stripping length: 12 mm (0.5 in)
