Carl, We experienced a rash of Comm Card issues with several SE installs over several years, but none exactly as you describe. Our issues were almost all resolved with a board replacement, but a few were particularly vexing with many return service calls to get a resolution. We seemed to have the most problems with the single phase 10k inverters. In general, SE tech support was helpful, although a bit paint-by-numbers at times, as well as very slow to answer for much of 2015. As best I can tell, the issues have begun to settle down most recently. Howie
