Hello Tesla Energy forum...
I have the system listed in the signature installed for a bit less than a year. Tonight I noticed the lights flickering a bit and checked the Tesla app to see power draw and if we had switched to backup.
At first the app showed standby, then flickered to charging, and then to discharging. Less than a second on each status. It proceeded to do the same changes for an hour or so that I was checking on it. The state change seems random in nature.
I switched the setting for the system to self-powered from backup-only and don't see any oddities to the system while on that setting.
I don't believe the flickering lights had anything to do with the charging/discharging/standby indication in the app. The flickering just brought my attention to the app. That belief is based on monitoring for an hour where the lights did not flicker while the app's rapid state stage was happening.
After switching back to backup only. There has been no repeats of the rapid state change for the last hour.
20.49.0 SW version on the Powerwalls. Powerwalls were sitting at 98% SoC when the flickering was happening. The system was on self-powered until the SoC reached 96% when I changed it back to backup.
Thoughts on if this was a battery management behavior that I caught or maybe a CT clamp issue?
I assume it to be a CT clamp issue. How best to check the correct operation or insure that the position of the CT clamp is correct?
Anyone have a good document/reference for the Powerwalls battery management system that includes behaviors?
