Weighing in ... 1)At a recent SMA Inverter Training, we were cautioned that the Deltas were not UL listed. Like many of us, I was already well aware of that. What was interesting, was the trainer specifically recommending we NOT use them, for reasons related to liability.
2)At a different training, by a well respected professional engineer who frequently posts here, they were judged to likely be as effective in preventing damage as a voodoo doll. 3) If one "ruptured" while someone happened to be standing in front of it........ 4) Why aren't they UL listed?
