Trying to let go of the reins of power control and from my addiction to the Tesla app (looking at 20+ times a day) for energy cost savings...but not so happy with current advance control mode. Asking for advice...
Have 20.4 Kw solar roof, PWv2 x 3, on PGE EV2A rate (nonpeak rates 12mn-3pm), but overall solar production est to be only 2/3 of annual demand (we are energy hogs). Priority was solar glass with new roof and aesthetics, to get rid of peak/part peak demand rates (by history was roughly 20% total energy use on same rate plan) and minimize total energy cost, and less of concern of power backup for outages in NoCal - SF Bay area (which now maybe a little more predictable) but want that when needed.
I have been switching between backup only mode to charge powerwalls to 90% during non-peak then have reserve to 20% to discharge during peak rates on Self powered mode. This eliminates all peak rates during the worst of winter months and used all of solar generated to home use and minimize grid use. But this is a daily switch process and active monitoring of when to switch back to self powered to not overcharge PW and depends on weather of day and est solar production.
NOW, trying to let go of control (kids complaining that I am looking at my phone too often)...
used Advanced TOU cost savings mode, BUT it seems to want to charge PWs to 100% then favors using solar excess to NEM during later non-peak time and peak 3p-5p (current sunset). I assume this will only continue to increase my NEM credits as we go into spring - summer production.
I get that I am loosing some power (10%) in conversion solar to PW to home use. But my concerns are:
1. I will accumulate NEM peak rate credits that I will never use in end annual true up and get terrible credit reimbursement (? $.03 / Kwh) when I could have just used them for at least other nonpeak use ($0.17/ Kwh - $0.017 /Kwh conversion loss).
2. MY conditioned mentality from Tesla EVs of not charging to 100% imparts the same worry of longevity to PWs auto charging to 100%
Seems like it would be nice to have more control parameters on Advanced mode, but wanted to know how people would currently do differently?
Thx (sorry for long post)
