My powerwall was installed around mid-Dec, 2017. So it's been two months now. It is working as expected with my Solar City solar panels. Our area was hit with power outages in late Dec and early Jan 2018, both times powerwall saved the day, our area lost power for almost 3 hours, and we did not even notice it. I've read in the manuals that "scheduled" or "Time of Use" functions will be coming soon in early 2018. Does anyone have more info? Thank you!
