Does Powerwall 3 support powershare now with no need for gateway?

[Tanquen]

Yeah. The peaks are the heat pump. I have it set 64 at night and then 67 when we wake up. Jumps to 69 when we get home at night and then back to 64 before bed. It's a 5 ton unit which I dialed back to 85% of it's capacity. I started an HVAC LLC and got the unit, a Carrier, myself. Here you can buy scratch and dent Carrier without a dealers license. Paid $5k for a $28k set-up with only minor dents. Knocked most of them out and they look brand new.

I think mine WAS $24K after rebates. I know the labor is more expensive here in California but I'm pretty sure I got ripped off and the units too big for the 800 square foot house.

I wish I hadn’t listened to the dickheads who sold me our new central air system and put mini splits everywhere.
amazing how “experts” tend to recommend what’s in their financial best interest and not yours.

I was trying to do as much research as I could at the time between the 18K and the 24K At least I didn't go with one of the no less than three installers that recommended a 30K BTU unit.

Just got this email from Tesla about Powershare today:

Powershare with Powerwall​

Hi, We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy. The Tesla Team​

Same. Just got it too. You beat me to it!

got the same email...
feels like they will push it again and then cancel the program just like the range extender

Yep, we’re toast. Fuckety fuckery fuckety. Elon first talked about putting the kids in the car and sending them to school without a driver in October 2014. It is now 11 years later, and my sense is that my grandkids, who weren’t born then, will graduate high school before it happens. I do actually believe that unsupervised FSD may eventually happen, but think that because bidirectional charging is limited to the unpopular and low-volume CT, it makes no sense to prioritize further development of this function, even with incoming class action lawsuits and an eventual settlement. This email is Tesla keeping the dream alive to avoid the actual day of reckoning that they know is coming.

Living in AZ, I think minisplits would become problematic trying to account for closets, halls, bathrooms, etc. Unless you want to close the door of the toilet closet and use it as a sauna, then walk out to the living room and enjoy a cold plunge.

I never even got the email. And I just got my solar and PW3 installed a week ago ready to enable the power share with the gateway 3 update. Now to wait some more. The single Powerwall 3 is not enough to really run my house nicely as I expected to be able to. I'll have to treat the PW3 like a 120v generator and run minimal things to make sure I don't run it down before the sun comes back out. Basically just the refrigerators. I planed on being able to run my central HVAC but that would easily run the PW3 down well before the sun comes back out to charge it.

I am supposed to have another 8 PW worth of batteries that I could tap into through a firmware update but now it feels like for a real power outage, where I'm out of power for over a week usually after a hurricane, I'm not much better off then when I would back feed my 120v generator to run the fridges. I just won't have to buy gas. I sure hope they eventually follow though with this because I would have just went with the regular power share setup and saved $30k if I didn't believe they were going to do this. My original plan was buy cybertruck, charge up and install power share just to run the house just as if it was a power wall 3 with 120kWh of batteries. But I got sucked into the dream of a gateway 3 with a firmware update.

I don't want to go this route, but if they don't release the update, I do have an idea now that I see how the Powerwall works. Theoretically speaking, could you back feed from the 14-50 in the bed to run my house directly from the truck and some how fool it into thinking it was grid power? Maybe kill the grid breaker in the gateway, let the house run on the battery shortly and then feed into a 14-50 outlet connected to the gateway just after the grid breaker to fool PW3 into thinking the grid came back on? That would be capable of sending 9.6kw continuous. Then i could set the app to charge PW3 from grid, which would really be the cybertruck, and also set the backup amount high so it would just pull from the truck instead of the Powerwall? There has to be some kind of workaround and it seems like that might work. If not, does anyone know how it would work I think it's a little sketchy messing with the gateway to do this but is seems possible.

If that is a no go I know it could back feed the house if I just kill my main breaker in my old breaker box and feed the power into a NEMA 14-50 outlet. That would give me a 40amp continuous for the whole house to run on just like people back feed 240v generators. I'm just not sure it would handle starting my HVAC when it has it's large amp spike on startup.

Add a soft start to your AC so it doesn't surge so much, then it will likely run, depending on your overall power requirements, and how big your AC is.

Yeah, those online estimates they show you in the marketing material is way overly optimistic. I've got a small 800 square foot home and with a brand new heat pump HVAC unit. I'm lucky if I make it from sundown to 5 or 6 in the morning before the battery runs out and that's without giving me any reserve for an actual power outage.
