<p class="MsoNormal">IP ratings are cumulative so each rating level includes all previous level of performance. IP62 is good enough for “rain”. IP65 turns that into howling raging jets of water.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If the manufactures says the product is IP65 rated and gives no other specific installation instruction in the product manual, then there should be no need for additional “protection” from water. I saw this product advertised as “outdoor,
wall mounted” on one web site, which is consistent with an IP65 rating.<o:p></o:p></p>

<p class="MsoNormal">So where does that leave you with this manufacture?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Well you don’t have a leg to stand on if you are in the warranty period and no water enters the enclosure after being subjected to jets of water.<o:p></o:p></p>

<p class="MsoNormal">I’ve been reflecting recently about IP ratings and my new opinion is that IP55 and IP65 ingress ratings mean “somewhat outside”. Many manufacturers with these mentioned ratings (which are identical for moisture ingress and vary only slightly
for dust ingress) will explicitly say that their product cannot be exposed to direct rainfall or moisture…which doesn’t sound very outdoor rated to me. Take this IP65 rated battery manufacturer’s installation recommendations for example:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">“The Battery Pack must be kept away from direct sunlight and rain or other sources of moisture.<o:p></o:p></p>
<div>
<p class="MsoNormal">This applies to both indoor and outdoor installations. Even if installed indoors such as basement or garage, direct sunlight and rain or other sources of moisture may still penetrate, so it is essential to protect the Battery Pack from
direct sunlight and rain or other sources of moisture”. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I get the sunlight part, but protecting an ESS from moisture when installed outdoors seems like a tall order. <o:p></o:p></p>

<p class="MsoNormal">I don't know what you mean by unprotected. That is exactly what an IP65 rating suggests - outdoors, subject to the elements. Nowhere does it say in the product literature thay it must be "protected," whatever that means. Protected against
the environment that it is rated to be in? Seriously?<o:p></o:p></p>
