so how much solar/pw did you have, and what did you change to? What was the driver for the upgrades?It wouldn't be surprising to see the behaviour that you saw. Tesla also just finished my install (an addition to existing solar and Powerwalls). The new Powerwall did not immediately start charging when it was added to the group even though I had solar. All the solar was being consumed by the house (and I suspect would have gone to the grid if I had surplus).
We did a grid off test and then after that the Powerwalls (old and new) started charging. Now the Powerwalls are consuming all the solar being produced (currently in off peak) presumably to bank for the upcoming part peak window.
