Powerwall charging

Will the Powerwall charge if it's put into "Backup only" mode and it's not fully charged?

Yes

yes, it will charge up to what you set the backup limit to. I use our PW2’s in self powered mode, sliding the backup setting up each day to direct solar to battery, and slide it back to 5% in afternoon to access batteries after sun goes down.

@Tesla-David - do you have to do this manually every day?

@Patrick, I have only been doing it during the Winter, as our solar is so limited up here in Edmonds WA (we only averaged 8.4 kWh/day in December, but are averaging 12.2 kWh/day in January). The solar is ticking back up now, and I have not been sliding the backup every day now, especially when we get >20 kWh/day. Even with the limited solar and PW2 charging the PW2 batteries have been absolutely amazing in reducing our grid draws, and can hardly wait until we are back into 100 percent self powered mode. We should be doing much better in February getting to that goal.

Can anyone help. We are in uk 1PW2 4kw solar. I have found a deal with very cheap nite but expensive day.
Set up the Tesla to charge max off peak, cost saving, worked well at first waking up with 100% battery, now i believe Tesla have changed the software to use forecasting. Some mornings we wake with 20% now and end up using high rate energy.
We are at the point where we may need to change tariff again. Is there any option where i can control it fully, as it is my battery and not Tesla’s!!!!
Thanks in advance.
