Has anyone here had an issue with Powerwall 2 not charging? I had my PW installed two weeks ago for backup-only purposes and after some initial wiring mixup with the Neurio, everything seemed fine. The Powerwall charge level after installation showed 87% and stayed at that level for about a day when i decided to trip the main breaker to test the backup function. Backup mode worked fine and after a couple of hours, the battery charge went down to about 76% so I reset the breakers... The next day, the charge had dropped to 74%, then to 73%... I called Tesla support twice and they twice told me that someone from their escalation team will call me back. But nothing happened. I restarted PW and the gateway but that did not help. Its now at 65% and falling... Anyone here who had a similar issue?
