I have recently replaced a go power charge controller with a Victron MPPT 150/ 100 smart controller, a smart shunt, a cerbo GX and a GX touch 50. The cerbo GX and smart shunt came up on the app as soon as I started up the system, but the smart controller will not. I have restarted my I phone, unplugged and shut down batteries and solar panel input, but still nothing. The controller shows on the touch 50 display screen and shows power coming in and charging the batteries but nothing on the app. Any ideas???
