I was thinking the same when I looked at the picture. Maybe someone cares to lookup the breakers and see if these are rated for DC.

jmelson:
What's amazing is the half-melted unit appears to still be running!  The LCD display shows system readings.

I think this thread shows that due to the possibilities for damage due to bad design or installation….these kind of "fairly big power" products  would best  be  designed and built in the country/area  where they are installed. If the company with the design expertise for this product had been Australian... in Australia, then  it could have had knowledgeable installation techs to sort this kind of stuff out. Because the west is  generally  clueless about anything to do with a power supply….the knowledge needed to avoid this kind of thing is well too scarce.
We have massive numbers of multi-millionaire western middle-men, who are clueless about electronics, bringing this stuff in, whilst pressurising the Chinese designers to produce this kit at a very low cost…the results are here for all to see.

If you buy non-certified crap and have it installed (even worse if not installed properly on top of it), it's 100% your responsibility. Not the responsibility of the current state of the power supply industry.

It is not black & white like that. If equipment fails CE emissions testing the manufacturer may opt to rectify that by supplying external filtering components and/or specify mounting instructions. If the installer gets it wrong then the installation will cause more emissions then expected even though it passed CE emissions testing.

I fail to see how this related to what I said just above. ::)
Installation was potentially part of the issue as I mentioned.

I may just modulate the "100% your responsibility". It is if you knowingly chose to buy crap, do the installation yourself or hire a dodgy installer. But I admit it's not if you got scammed, meaning for instance you chose an installer that seemed legit, they chose the gear themselves, installed it for you, and all you did was trust a professional. In this case, it's the professional's responsibility of course.

And I'm still failing to see what it has to do with the state of the power supply industry itself, which was the main point.

Wow that could have been bad.  Would not necessarily blame the owner though for fact that it was junk.   He probably just went on Amazon and searched for solar charge controller and shopped.  Seems most of the stuff that's readily available is junk.  It's harder to get the good quality stuff it seems. You really need to know where to shop and it's not as obvious to find.

I personally look at prices, anything that abnormally low, I assume it's going to catch on fire, and not get it. Not the best metric to go by though. Also can't go by reviews since sometimes they switch the product around.
