Q
what do IP65, IP67, and IP68 protection ratings mean
A

IP67 and IP68 mean:

  • IP refers to Ingress Protection,
  • 6 stands for Dust-proof and
  • 7 for Temporary immersion, 15 cm to 1m, and
  • 8 for Permanent Immersion, under pressure

solar panel junction box with an IP65 rating will provide complete protection against dust and cannot be damaged by low-pressure water jets. There may be limited ingress inside, but it stops the component from properly functioning.

solar junction box with an IP67 rating is completely protected from dust and will properly functional after Temporary immersion in water (up to 1m deep).

PV junction box with an IP68 is completely protected from dust and cannot be damaged by immersion in water deeper than 1m.

quality solar panel junction box is certified (IEC61250, IEC61730, and UL1703).
