I'd like to get my powerwalls to charge only from excess solar, but they seem to always take 100% of the solar until full each the morning.
The Tesla web page says in Self Power mode, it should be charging from excess solar, but that does not work for me.
I'd really like to reduce the amount of solar pushed back on the web during the day. Due to a screw up by my installer, my credits are capped at 3.9kW, so anything after that is just free to the grid I get nothing, So I'd rather charge during that time for use later during Peak rates.
Has anyone figure out a way to get it to only ever charge from excess solar? I don't mind change modes and reserve level during the day (will set up a script to do that eventually)
My idea set up would be: hold off all charging until around 10am, then charge only excess solar until 4pm, then switch to the house running 100% Powerwall from 4-9pm, then 100% grid until 10am the next day.
