Well things were working fine, but in wanted to switch around the order of the two inverters (MPP LV6548). SA was seeing the slave as numbers one. This happened once before and I just switch around the direct cables and plugged the master in first. I did the plug swap at the pie unit since I don’t like jabbing the little micro USB into the head unit. Well it swapped positions but now when I go to settings and look at the second inverter I see connection “via parallel cable”. I swapped cables, different brand cables, changed ports in the SA, rebooted the SA, unplug it totally, rebooted the inverters but nothing gets full data back. Using either single cable just to the second inverter it fails to connect and the SA is constantly searching. I’m thinking that the usb port/network in the second inverters head unit is toast. Ideas? Kinda weird since I didn’t move the cable at the inverter end at the beginning of it all.
