The system is designed when on-grid to send PV or powerwall power to offset those loads which are not backed up. I would say it causes issues with the algorithm for there to be large house loads that are NOT monitored.
Is that not ideal in my case per the comments (below quote) wrt the monthly cap on directional generation? EV’s suck a lot of kWh, and so if I added CT’s to my non-backup load, and the GW2 sees the consumption during say AM or midday onto my EV’s, it will dump power from PW to grid to compensate for this? But this would be at off peak times, and thus PGE will prioritize this toward my export credit limit for the month?
I really just want to see the non-backup loads in my Tesla app for visual purposes, and to have the data logged…but I think I actually don’t want it to consider those loads in its algorithm.
It seems this is the best reason for me moving both EVSE to the backed up loads side, as any draw those take off the Solar or PW will be NOT included in my monthly export cap, allowing me to utilize maximum amount of PW for time shifting TOU arbitrage.
PG&E takes the most advantageous (for them) interpretation: they remove the excess export credits from highest rate period first. I ran into this once when PG&E double-billed me by accident.
