If Elon's dream of an electric world comes to fruition I have to believe this issue will become more common. By the next year I will have a MS, MX and Volt in my garage. My current idea is to use the charge scheduling to "rotate" charge times at night with HPWC's for the Tesla's... but is there a better way? I suck at math but it seems at some point we could max out the service to the house. Your thoughts? Anyone else have similar issues?
