I recently signed up to add 3 Powerwalls to my home and am trying to decide whether to put the EV charging circuit on the panel with loads backed up by the Powerwalls. I see on the Tesla site that the smart features for controlling vehicle charging during an outage are only supported for cars US MS manufactured in 2014 or later. So we should be fine for our 2015 MS, but the 2012 Signature MS seems to not support this feature.
Does anyone know what happens in practice when an older MS is set to charge during an outage? Does it just plow ahead and drain the battery? If so, are there work-arounds such as installing a wall charger? We currently have the mobile charging cable plugged into a 50A outlet.
I realize I could install a second outlet and only power the 2012 MS from the grid loads, but it was several $K to run the first outlet to the detached car port and I am not keen to have a second line run.
Thanks for any info/advice!
