My electric company (LA DWP) may not be willing to give me a Time of Use meter. I have a solar meter that runs backwards when my Tesla solar panels create more power than my house is using. I'm thinking, why consume discharge/charge cycles on my Powerwalls when I can just send the excess power back to the grid and get full credit for it? If I had a TOU meter, I'd fill the PW before peak pricing starts at 1 pm, then during peak period, send any excess power to the grid for maximum value creation, and draw down on PW on cloudy days. Once off-peak starts, I can re-buy from grid at lower prices. But since I don't have a TOU meter, and may never be allowed to install one, doing that just chews up cycles on the PW. There must eventually be degradation of the PW with constant charging and discharging. Shouldn't I just set the PW to 100% for use during periodic blackouts, and use the grid as a virtual battery? Tesla told me that unlike their battery packs in their cars, it is not a problem to keep Powerwalls at 100% charge level.
