We don't install Tesla products often, where do you source the comm cable from the PW3 to the backup switch? It references that it's TCER 18/4 with the comm pair twisted, I can't find any specific supplier? Enphase has their own comm cable which looks very similar, is there a specifi cable for PW3?
