2 Weeks ago I installed a 75/15 with Solar panel in my campervan I set everything up using the victron connect app and went on a trip. All seemed ok. Since I came back the van has been parked up for 3 days. I decided to see what the status was using the app. I can connect to my controller but the app no longer shows any real time or historical data. All I get is the option to change the password upgrade or change the name. I upgraded when I first installed the unit. I also notice that none of the LEDs on the controller are lt. I have checked and there is voltage from both the battery and Solar panel on the terminals but dont know if its working because I cant see the real time status screen on the app. I have tried disconnecting\reconnecting all the cables and it made no difference. Any help\advice would be appreciated. The controller surely cant be faulty after 2 weeks.
