Greetings, just got my Powerwall online after waiting since lat June. My first full charge was wiped out in < 2 hours when Tesla 1 started charging at midnight PW discharged at 5kW. Tesla 2 is set to charge at 3:00. It was fully charged off the grid. My 1 PW has its own sub panel with nothing exceeding 30A. The two chargers (and pool) are connected to the main panel with each having their own 50A. How do I separate the two? Can't I keep the PW for the house and exclusively use the grid for the teslas? What ate the rest of you Tesla+PW users doing? Oh - it is charged with a 7 kW PV system. Thanks!
