Charge By Solar Not Showing
- Thread starter Vapor
- Start date
Yes, same scenario for me. I was able to update the Model Y to 23.26.7 yesterday and the charge on solar options didn't appear until today. Seems to be working now, just wish I could set the priority to charge powerwall first before charging the car on solar. I set the powerwall to 100% to force the system to charge powerwall first. With that said, I just set powerwall to 20% and now it is partially charging model y on solar and majority of solar power going to powerwall which is ok too as long as powerwall fully charges by peak. I'm on time of use settings.

That's interesting. Mine does charge the powerwall first and then uses Charge by Solar after the powerwall is full. It has some message about prioritizing the powerwall in the app when it does that.
I did notice in your setup you seem to have two powerwalls where I only have one. I wonder if that affects how it all works?
Strange, mine still wants to use excess solar to charge the car first as priority over charging powerwall. I noticed earlier it was partially charging the car because I accidently set the model y charge limit to 9amps instead of max charge limit.
I have received two types of messages indicating powerwall priority…
I’m also using ChargeHQ now too, so unsure if that’s what is prioritizing the PW. But clearly that wouldn’t create either of the messages below.
For those people just getting the FW on their cars, it seems you need to wait ~24hrs after the install for it to appear in the app. It seems to do something with a “key” and then you confirm your home address and there appears to be a handshake with the powerwall.
Lastly, it appears the settings for CoS moved into the … menu. Only when I click that can I now set the CoS limits.
Hoping they add support for multiple cars soon!

I have the first two screens in my app for both cars but only the traditional single limit shows on charge screen. The option appeared for each car about an hour after the FW upgrade and in both cases it did the pairing thing to the powerwall and something with the car keys. My powerwall energy graph now includes a car section but it shows zero for the charging it did.
It almost seems like that was an interim step when activating my second Y. Today the sub menus are gone and the double slider on main screen is the only way to adjust. Weird.
Attached is what i'm seeing right now in the app. I haven't messed with any settings, other than setting the charge with solar to 80% and the charge from any source to 70%.
I believe this is what you're wanting it to do. If i'm confused though, let me know.
One other thing to call out, i did notice that the individuals who seem to be having the issue have multiple powerwalls, where i only have one. Also, my Powerwall is on version 23.12.11. None of this worked until it updated from 23.12.10 to 23.12.11.

Not for me...and if they made such a change, it would not be useful to me except during winter.
Just on the phone with tesla PW support and she told me she has never heard let alone seen an option for the powerwall setting before car charge.
Does anyone else have the option, and how did you get to show?
Once the PWs were at 100% the vehicle charging started. Just like it should be!
