My distributor keeps pressuring me into giving them remote access to my system. I don't really trust them as they haven't demonstrated much professionalism in their after-sales support. What could a distributor diagnose remotely that a qualified engineer with the proper tools couldn't diagnose with direct physical access to the entire system?
My system consists of a CerboGX/Touch50, Smart Solar 250/100, Multiplus 48/5000, and Pylontech US3000 batteries. The problem I'm having is likely due to the Pylontechs.
