With regard to Tesla, I am only talking about (from my understanding, correct me if I'm wrong), is the requirement for internet connection in order for the system to function. They will shut down the system without internet connection if down for 2+ days.
I am not really interested in the Tesla, just the SMA/Sol-Ark and the pros/cons discussed in this thread as well as trying to determine the vulnerabilities of each. There was an assertion that the Sol-Ark monitoring servers are located in China. There was also discussion that Sol-Ark limits open source data collection for security (hacking) reasons. I am trying to wade through this info and discover what is true, what are the vulnerabilities and does SMA (the other inverter I'm considering) have any similar vulnerabilities and/or requirements with regard to internet connection, monitoring, warranty etc.
