Hi all new to the forum, i have a 300w solar panel on my camper roof with a smart solar mppt 100/30 and an orion dc to dc 12/12-30 non isolated connected with a smart alternator system (sprinter 2017). All was working fine for a few weeks and during the recent hot weather I decided to have a look on the app to see what the figures were like with all that sunshine. Solar setup was fine but no lights were working on the orion where normally i would have the power light and the bluetooth light. The icon on the app was black and not accessible. I tried to uninstall the orion and reinstall it but now the app cannot find it. I checked and double checked all connections and fuses but all ok. I read on here to disconnect the starter battery input for a while to reset it but still nothing. If anybody has had the same problem and managed to get it resolved please share.
