Powerwall 1.41

I’m in Arizona with a relatively new install (PTO 10/18) and got 1.41.2 on 10/31. So far my self-powered scores seem to be much higher and the system seems smarter about when to discharge the Powerwalls on Time-Based Control. Lots of variables though so not sure if it’s the software update or just having more history and cooler weather.

May as well add some observations from AU install, so it may not be the same for everyone and the tesla mobile app only shows in 0.5W amounts so you won't see any/all of this, just used 0.3W grid for the day readings

  • Version 1.41
    • Added support for utility grid connections in Switzerland
    • Improved energy performance
    • Additional support for 3-phase Western Australia grid compliance
so still on 1.41.2. with PV.
  • Charging from grid in backup mode now only pulls 3KW (used to be 5 when last tested)
  • Charging from grid in TOU set to 100% reserve pulls 5KW
  • Didn't auto charge from grid when was already in standby at 14% reserve from night before with 16 hours of peak ahead (seasonal setting? it charged itself in winter and start of spring to avoid peak)
  • In off peak time is where I'm guessing Improved energy performance actually is, so off peak drains slower if it's on battery?
ok off peak from midnight until 7am it's like the battery doesn't attempt supply the reactive power anymore (Q) and then sometime during the peak period sends back the overnight used grid amount.
Figures are every 5 mins from the powerwall counters which is why battery flow is 120, 240, 360 etc. peak starts at 7am, the 7am reading is from 655-7am
