I'm commisioning a system using 2 x 150/45 charge controllers. Also has a 48volt 1600Va multiplus inverter. These are connected to a venus GX for remote monitoring. The venus has a ethernet cable connected for internet connection. It also VE cables between charge contollers and the Venus unit. The multiplus is connected to to the Venus via a ethernet type cable. On site I can see the charge controllers on Victron Connect but nothing else. What am I doing wrong
