Finally figured out grid dependence...then, today.
So, spent some time trying to figure out why I was pulling so much off of the grid. Turns out that my system was transferring from my battery back to the grid at peak times. Since PG&E only pays me $0.03 per Kwh, I was basically losing money for every KwH being moved back to the grid.
After changing the settings, the export stopped and I started using only 0.4KwH from the grid on sunny days.
Until today.
Today, it apparently decided pull from the grid this morning to recharge my batteries, even thought the panels were producing. my battery hit 35% and then it started importing to recharge. as of 2:35pm, I'd pulled 21Kwh from the grid. it pulled $8.50 worth of electricity ($0.40 @kwh) from the grid to recharge. I'm now pushing excess solar back to the grid at 0.03 per kwh.
I called support and they claim that my microinverters are talking top another controller, three houses away from mine. WTH. is this even possible? Can anyone explain what might be going on. That house is at least 100' away from mine...and why would the microinverters pair to that system? it makes no sense to me at all.
Unimpressed, out real money, and a little more than aggravated that the system is so colossally unreliable.
