It could, but given you've got white rings, odds are they don't get all that warm. I can't really tell where your epoxy is (a good install). It's not impossible that the ring was only solidly fixed at two points and managed to vibrate/pivot about that axis. One good whack against the backing and it could crack.I as thinkin it could have been the heating/cooling, expanding/shrinking of the glass over time?
Six months for me so far. Doesn't mean they'll last forever, but so far I'm pretty happy. I'm strongly guessing the XE inverters are a lot more reliable than the older v1 and v2 inverters.I love AAC's look, but man do they seem to be having quality control issues.
