My Victron setup is 2x Quattro in parallel to VE Bus, 2x smart solar mppt and the Skylla-1 in parallel connected to a Cerbo GX via VE-Can also a REC BMS is connected to VE BMS everything works well. As soon as I connect the VE-can to NMEA 2000 cable the Skylla-i goes into error mode. All the cables have been replaced with the exception of the ve-can to nmea2000 cable. When I remove the VE-Can to Nmea cable the Skylla-i comes back to life. When the Skylla-i is removed from the parallel string the VE-Can to nmea 2000 cable doesn't cause any problems. When the Skylla-i is running stand-alone (just with the control panel ) it works fine also, I also have swopped the ve can ports on the Skylla-i and the Cerbo GX but it makes no difference. I haven't got the fuse installed in the VE-Can to nmea2000 cable as my Maretron network is already powered. I also tested my new spare Cerbo GX same results. Any ideas???
