Update:
I performed a full system shutdown and restart, grounded my PV array separately and removed some panels from two of my strings to drop my voltages. Each of these changes has seemed to help. I am no longer getting power outages that last 1-2 seconds and switching power to grid.
I am now getting outages that last less than 1 second, even in the middle of the night with a steady low load. Working with the techs to determine the issue as it is not apparent in the data logs. I do see some small irregularities with battery voltage...
Finally about being able to reach support, I was calling a different/incorrect phone number trying to reach support which was never getting me through, it had a slightly different phone tree. 903-441-2090 is the correct number for me.
