Haha, yes. Although I've love to have 500+kW per phase... it would take me half a minute to fill up from empty to full... take that EV haters!I think you mean 500+W

I’ve just turned off Charge On Solar to see what would happen. Those three dots were there while I had it activated but now that I’ve used the toggle to turn it off, the three dots have disappeared. See attached screenshot. There is once again no way to turn it back on.Yes, you can turn it back on. The 3 dots are still there to toggle it back on - but the car has to be plugged in to see them. I have v4.30.5-2528 of the iOS App.

iOS app version 4.30.6-2531. Car on 2024.2.7. Tried restarting the app. Rebooting the phone. Starting to charge the car rather than having it on standby while plugged in as per the screenshot.
Yes, still paired. In fact, there's my phone twice. A previous pairing before I deleted the app & reinstalled it which I had to do last time to get the COS option back again. I'll give the unpairing/repairing thing a go.Does the App under Energy settings still show your phone as having been paired with the Powerwall? Try un-pairing and pairing again.
Welcome to Australia!My apologies for not properly considering the Australian context. The net metering which is common in many parts of the world pays the same rate in and out, and as such there is no financial reason to attempt to direct your loads to when you are generating. In the case you describe above, with a high price from the grid and a low price out, there is a strong financial incentive.
Whether there is a green incentive is more complex. If they will shut off other solar farms because you are putting more power onto the grid from your home, then there is a green benefit to you balancing your loads and generation. That will become a bigger problem, as I pointed out, when the mid-day solar surplus increases. It is actually forecast by some that prices for power at noon will go negative, though that's a problem that should fix itself as both storage facilities, and cars, all work to try to charge themselves on negative-price power. This is why most charging stalls should be at offices eventually, you want them in places cars are plugged in mid-day. Today, most stalls are at homes, because night is the most convenient (and currently cheapest) time to charge. Of course if your car stays home in the day, the home charging station is a great place to get that negative price power, if they offer it to residential customers.
The solar power of course is not negative priced, but if there's a glut of solar sold on a low price contract, the power sources that can't easily turn off (nuke, combined cycle, wind) will go to negative prices. Solar, hydro and peaker natural gas are so easy to turn off they can go cheap but don't need to go negative.
There's already a mechanism to pay for that kind of thing in the NEM, it's called the Wholesale Demand Response Mechanism. Registered Demand Response units bid, are dispatched and are paid like a generator.If a few thousand Teslas charging at 7½kW could slow down simultaneously during a brownout & thus prevent a blackout, why not monetise that? It's a grid service, it should be worth real money, so give us some incentives.
Anyone else have issues with car not going to sleep since charge on solar came through? I seem to be down 5-6% everyday.
Thanks. Have been in NZ for last 2 weeks and car was not sleeping. Ironically I logged a ticket last night and lo and behold the car is sleeping today....I initially thought that my car wasn’t going to sleep either after I set up CoS. Because whenever I swiped across in the App to switch from PW2 to my vehicle to check something, it always responded immediately, as if it was already awake. Previously you’d get the spinning wheel and it could take anywhere from 10 seconds to a minute for the car to respond. And sometimes never, and I’d have to wake the car by going to the garage and opening a door.
I’m pretty sure it is sleeping now that I have turned CoS off - and I will only turn it on again manually if my car needs a charge and my PW2 is full. I would notice if it was losing 5% a day and it isn’t.
However what I have noticed is that the car seems to wake far more quickly via the App than it ever did previously. This could be a result of Tesla migrating from Owner API to Fleet API which works better, or the latest software update, or both.
AndroidAre you on iOS or Android? . I’m on iOS and as soon as I paired my phone with PW2, the CoS controls appeared. I didn’t have to logout, or restart the App, or anything.
Yes, it's plugged in.And this might seem a dumb question… but is your car plugged in?
I have the charging controls but no three dots to open the CoS parameters.Even if it’s not plugged in, tapping the lightning bolt icon on the App will open up the charge port and the charging controls should appear, including the 3 dots in the upper right corner of the charging panel, from which you can set the CoS parameters.

Mine is set to Self-powered, but has been charging the battery initially. I can't work out the pattern, but it adds roughly 10% to the battery before it stops and switches to charging the car (and then eventually charges both when the solar production reaches a high enough level.Tesla defines what gets priority (battery or car) based on the Powerwall configuration (https://www.tesla.com/support/tesla-app/charge-on-solar):
- Storm Watch (if detects an event coming) - Powerwall gets priority, then Car
- Backup reserve - Powerwall gets priority (up to the set Backup reserve percentage), then Car
- Self-Powered - Car get priority (until limit), then Powerwall
- Time-Based Control - Powerwall gets priority (during Peak), then Car
- Go Off-Grid - it depends
I have mine on Self-Powered but I'd like to prioritise the Powerwall, they should have it as an option.
Is your battery backup reserve set to 10%? When it's set to self-powered, it gives priority to the battery up to the battery backup reserve, then the car.Mine is set to Self-powered, but has been charging the battery initially.

I meant that it adds about 10% above my reserve (so I end up with 20% or so in the battery) before it prioritises charging the car.Is your battery backup reserve set to 10%? When it's set to self-powered, it gives priority to the battery up to the battery backup reserve, then the car.
