IP55 / IP65

Hello,

I'm looking atbattery and inverters but want to mount them externally to save space indoors , As far as I can make out IP55 and IP65 are ok for ourdoors although some people I have spoken to say IP65 is ok but not IP55.

Any experts out there ?

Cheers

    No, but the basics of IP numbers are simple enough.

    The first digit measures dust proofing. 5 is ok, 6 is the best.

    The second digit measures water resistance, 5 means it'll withstand light spraying.

    Many exterior light fittings are IP44 (example). Take that as you will.

    Guide here.

    IP Ratings Chart

    The IP (International Protection) rating given to a piece of electrical apparatus is a two digit code indicating the degree of protection its enclosure affords it. The first digit represents protection against penetration by solid objects accessing hazardous parts, the second describing the enclosures, protection against the ingress of water. An X in place of either digit means that either the enclosure has not been tested or that the test is not applicable.

    First digitMechanical protectionSecond digitWater ingress protection
    0No protection0No protection
    1Protected against solid objects over 50mm, e.g. accidental touch by hands1Protected against vertically falling drops of water e.g. condensation
    2Protected against solid objects over 12mm, e.g. fingers2Protected against direct sprays of water up to 15 ° from the vertical
    3Protected against solid objects over 2.5mm, e.g. tools & wires3Protected against direct sprays of water up to 60 ° from the vertical
    4Protected against solid objects over 1mm, e.g. wires, nails etc.4Protected against water splashed from all directions, limited ingress permitted
    5Protected against dust limited ingress, not harmfull deposits5Protected against low pressure jets of water from all directions, limited ingress permitted
    6Totally protected against dust6Protected against strong jets of water e.g. on ships deck, limited ingress permitted
    n/an/an/a7Protected against the effects of temporary immersion between 15cm and 1m. Duration of test 30 minutes
    n/an/an/a8Protected against long periods of immersion under pressure

    NOTE: In the event of additional holes being drilled, pierced or knockouts removed, suitable measures should be taken to restore the product to its original rating IEC 529, BS EN 60529 does not apply tp protection against the risk of explosion or conditions such as humidity, corrosive gases, fungi or vermin. In certain cases equipment designed to be mounted in an enclosure will contribute towards the stated IP rating, (e.g. pushbuttons mounted in an enclosure). Different parts of enclosures can have different degrees of protection and still conform to the standard.

    Powerwalls are IP67 - I believe they are considered the gold standard in outdoor storage.
