My 1x Powerwall was installed 2mo ago and has been online for a few weeks now.
As a new and excited owner, I find myself checking power flow and whatnot on an almost daily basis. My PW is set to Self-powered with a 40% reservation because my panels output capability minus my home energy demand result in capability to charge about 60% of the PW by the time the panels production are eclipsed by demand. We routinely have power outages where we live hence the reservation.
A few days ago, I noticed the PW was not charging/discharging properly. I noticed that at 40% capacity, self-generated power was being sent to the grid. As a troubleshooting measure, I adjusted the PW reservation to a higher arbitrary number (72%) and ran it a day to see what happens. The PW charged as expected, and I then changed the reservation back to 40%. That night, the PW discharged to 72%, and began drawing from grid.
I called Tesla Energy and was informed that the two issues I were reporting were known with my current FW:
1) intermittent charging/discharging behavior accuracy
2) intermittent setting adjustment acceptance patterns (sometimes settings will take, sometimes not, etc)
The person I spoke with mentioned they would be calling a higher-tier of support and would call me back in 1H and did not get back to me. They mentioned communication to PW was not a problem.
I was wondering if anybody else on this FW had any issues. Thanks much.
