This is why:I have Tesla solar panels + Tesla Powerwall+ and Model Y car. I still do not have this functionality in the Tesla App. Any idea on ETA?
Hardware | Software |
---|---|
Model S, Model 3, Model X or Model Y | 2023.26 or Higher |
Powerwall with solar on site | 23.12.10 or Higher |
Tesla app | 4.22.5 or Higher |
Agreed, was excited to use this feature too.Such BS that this is not made available to pre-refresh S and X.

I have a feeling this is a way to drive people into new cars (no pun intended), Tesla is a business like any other.My only thought is, it must be a technical limitation due to "something" that is or isnt present in those vehicles (like how phone as key doesnt work for those vehicles).
I dont know that, im just guessing.
I feel for you all though, I really do.
I doubt it's anything more than just not allocating the programming time/budget to what is now a legacy OS build. I'm literally able to do what this feature does manually within the app, it's just far less elegant and convenient than something that would throttle the car's charge speed automatically.I definitely get why you (and anyone else in your situation) feels that way, especially since a "LOT" of "pre-Refresh" S and X customers were some of the customers assuming the most risk as it relates to purchasing Tesla vehicles at high price points and before it was pretty clear the company would survive.

Kind of makes me regret getting a Tesla solar system instead of Enphase stuff because Enphase has been able to do this for a while now. Third party is supporting Tesla's own products better than Tesla does.Agreed, was excited to use this feature too.
I mean, you'd think they'd perhaps even want to offer a feature to their customers who might have say, bought Tesla solar (without Powerwall) and a Tesla car, both in 2023; because this feature is arguably more valuable for solar customers without Powerwalls than those with, since your only choice is to export excess solar. But no....
They need to add a note:Tesla is about to sell out of these…
From the website explaining the feature, which I linked above:
====================================
Typical Operation
The scenario below shows typical Charge on Solar behavior when a Tesla vehicle is plugged in at a home with Powerwall. Notice that the vehicle will adjust charge power approximately every 10 seconds to match the excess solar power and power consumption elsewhere in your home.
===================================
If its only adjusting "every 10 seconds" then they need something with a buffer, since power on a home changes almost instantly.
Do solar only installs have the ability to measure grid exports or only solar production?That's what they say HOW it works, but it seems to me there's no point WHY it works that way if you have a Powerwall .... the Powerwall is such a massive buffer, there's no reason to adjust car charge power every 10 seconds, except to show off. Because all they're really doing in practicality is saying, don't export to the grid, which the Powerwall already does without a car charging - I understand adjusting the Powerwall charge rate every 10 seconds to zero out the grid exports.
But the Powerwall can get full, so you want to dump off to the car during the day. So even if you have a large solar array, and zero home consumption, let's say a 10kw array at full output. In five minutes, that's only 0.8 kwh, or about 5% of a Powerwall used as a temporary buffer. So then you can adjust the car charge rate in the next five minutes interval to keep your buffer at zero. Microwaving some leftovers for 30 seconds, or 3 10-second cycles? The Powerwall absorbs that in the buffer for 3 cycles, there's no real point to the car making two extra adjustments within three 10-second cycles. Wait, got a Model 3 that can only charge at 6 or 8 kw, so can't suck down the buffer? Well, the Powerwall is going to fill up regardless, the transient home usage spikes are minor. And I'm just using 5-minutes as a worst case buffer, basically 10 seconds, 1 minute, 5 minutes - there's no much practical difference if you have a Powerwall.
So it's really solar customers WITHOUT a Powerwall buffer who need to limit exports, but even then, you only need to do it to the rough granularity of the net metering interval, maybe say 1/4 to 1/2 an interval, since Tesla doesn't know when exactly an interval starts or stops? So I though the interval most POCO's net out import/export was like 5 minutes or 15 minutes - so even adjusting the car charge rate every 1 minute (so using the grid as a 1minute buffer) would lead to effective zero exports?
The only folks who really need a 10 second adjustment would be those who have solar-only with NO net metering, like those unlucky ones in states already where they are under NO EXPORT rules, i.e. not merely getting zero compensation for exports, but you're supposed to curtail rather than export (like Hawaii in certain neighborhoods).
So it's really solar customers WITHOUT a Powerwall buffer who need to limit exports,
It should work with any charger as the car regulate the rate of charging not the charger, once you have the right software in the car it should work/communicate with the powerwalls software, we will know soon.Im not arguing with anyone, as I said I feel bad for those who want this but wont be able to use the Tesla designed solution. I dont even know (for example) if its going to work with my gen 2 wall connectors, or require gen 3 ones, etc.
I have an Enphase solar sytem, and no power wall.
But I am wondering: with net metering, why would I even want something like this new feature? Are there still electric companies out there that don't offer net metering of any kind? Or am I missing something?
