72 cell panels are about Vmp=39V and Voc=46V. CCs need to handle this including variations for temperature. Most important for me was the size - 39"x79" and as a result I used 60 cell panels. Plus 3 series panels and my 150V CC maximum makes the Voc marginal, and perhaps out of spec considering temperature.
