<p>The Schneider RSD is decent. At least it is useable as a 600vdc disco. <img title="Wink" src="cid:smiley-wink.gif@sti.net" alt="Wink" border="0" /> The few offgrid homes that were required to use this had the Tigo units on the array panels and wireless comm to the RSD. As soon as the inspector was done, those went to Ebay. I never use a roof but have used a barn for panels. </p>
<p>AFCI, GFCI, and now RSD are just more things to fail when you need them the most, like during a wildfire or hurricane.</p>
<p>I know you folks have to do what you need to do to stay in business. For me, electronics are <strong>in</strong> a covered building.</p>
<p>Always!</p>

<div style="word-wrap: break-word;">I would once again say that; we as an industry can influence not only the writing of the code but with what we are <em>buying</em> OR <em>not buying.</em>
<div>If the devices we are required to install to make things "more safe & reliable", at the cost of our livelihoods & reputations, we all need to make the folks that are building the RSD crap and those who require installation of questionably safe & reliable crap aware of these problems.</div>
<div>WE can thru either going to the code development meetings AND NOT buying or installing this stuff. Not too easy when a huge amount of solar is rooftop installs. As many of the installers in the NE know its not a single level ranch were installing this stuff on, short season & man lift required.</div>
<div>Tell your supplier why you are not buying that brand, let your supplier & folks on the list what manufacture has good reliable products AND tech support that we can understand, who we can get in a timely fashion, and get the satisfaction of a prompt replacement. IF we don't sell it they won't have a job or a market.</div>

<div style="word-wrap: break-word; line-break: after-white-space;">Carl,
<div> </div>
<div>Did you get any kind of joy out of APSmart on that failure? </div>
<div> </div>
<div>I will say that their tech support guy did at least try to be helpful, but the language barrier was really really steep and their distribution channels are less than ideal. Their response to a request for compensation was that they would not be profitable if they had to pay for truck rolls for such a low cost item. I really don't think they GET IT. We've been in business for over 16yrs and this one failure could easily have ended that run.</div>
<div> </div>
<div>I cannot imagine we're alone here. I was told by AP that their failure rate was 0.2%. Now, I come from a reliability engineering background in petro chemical/ big pharma where a 0.2% failure rate would be catastrophic. Can you imagine that 2 out of every 1000 pills made could cause death? We engineered secondary systems and multiple quality checks to contain catastrophic consequences for components that had know failure rates higher than acceptable values. A simple solution to this fire initiation issue would be a metal enclosure instead of plastic casing. That still doesn't really solve the problem of extra connections though.<br />
