As I said before, the zeus worked perfectly well, outside of one minor issue, that was solved fairly easily by reprogramming it.
The addition of manually changeable fuses is (to me) one of the best breakthrough in the design compared to a HUB/SSC solution. In 2012, I had a few fuses blowing on some HUBS, and there was no way I could have changed them during the season. This year I was looking forward to having some blow on the Zeus

It would be great to be able to maximize the outputs. Currently the maximum load is 16 strings of 85 pixels, as anything above that ends up on more than one pixelnet universe. It is not uncommon to have megatrees with 32 strings of 50 nodes (16 folded strings of 100 nodes) or matrices of more than 1360 pixels. Of course, that means bigger PS but anyone going for those kind of numbers will not be stopped by the price difference between a 600W PS and a 800+W PS.
