PowerShare/Powerwall update

[Jethro]

I’ve been trying to get a solar system from Tesla (over $50K) that is compatible with my Cybertrucks PowerShare “option”. I received this information this morning from Tesla:

Per your request, here is the latest information on Powershare:
- Powershare is currently not compatible with the Powerwall.
- Powershare currently works only with a PV + Wall Connector (WC) + Gateway 3v (GW3v) configuration.
- This setup must be installed by a certified installer. Tesla Direct does not provide installation services for Powershare-enabled systems.

If you would like to move forward with your current order that includes both Powershare and a Powerwall, we will need to cancel the order due to the incompatibility.

Last emails that went out were that Powershare for CT with Powerwall would be mid-2026. There was a post of someone getting asked to join Beta for testing, but not sure how valid that was. Thoughts were it would be available via OTA in May or June. From the Tesla website today "Powershare will be available for Powerwall configurations soon through an over-the-air update."

Also worth noting that powershare with powerwall and solar has been "coming soon" since the trucks release. Every 6 months they say it's delayed again with no reason given.

understood it’s complicated for them to program this orchestration by the Powerwall/GW and Tesla Energy backend:

Solar out to PW
PW to House
PW to Grid in/out
Non PowerShare, PW to Tesla Vehicle

now add the Cybertruck in/out

seems easy but the Powerwall/Gateway are the orchestrator
Must be harder to perfect in/out of another device, cybertruck

will be amazing to see

what I would like is, scenarios:

max hot summer, cloudy hot humid day, Powerwall drains down running house and CAC, at 10% PW capacity, the Cybertruck battery now runs rhe house and CAC
No grid pull

Dreary winter day, PW drains down running house and heat, maybe also need Cybertruck for some coverage

Blackout, CT is added behind the Powerwall, providing load coverage during backout
As the CT runs down to 10-20%, PW capacity is brought back up so that we can run to supercharger and refill

it’s the Cybertruck battery joining the Powerwall for coverage

amazing coverage
Driving to an Tesla supercharger to provide backout coverage continuously
Prepers would love this

One thing I'd like to see is CT being used for those times when PW3 won't quite make it to the end of peak pricing, leaving me with a larger buffer for power outages.

I think the testing with CT being able to export back to the grid is a great sign. They're working on it.

I have not seen that, thanks! That would be good news, where did you find it, please.

Thanks for clarifying the “complications”. I figured that going with Tesla solar might make things easier with setting up the system the way it’s supposed to work, but it appears that Tesla doesn’t use their own installers AND doesn’t provide much support for those they do use.

My note from Tesla says they would not provide or recommend an installer for their PowererShare/Powerwall system...perhaps because of the Cybertruck. Sounds like they are finding a scapegoat leaving the customer in the dark while still collecting their $50K.

I have household medical equipment I need to support in an outage. In December power went out for 5 days. Solar/Powerwall would have helped. It makes sense to interstate in the Cybertrink option I paid for too.

Hopefully, Tesla is sincerely “working on it”. How might I find an installer for this system if not Tesla?

I see you're in Boulder. There should 100% be Tesla installers there. I'm by Loveland and Tesla came out and did mine. I might ask for a new rep and make a complaint.

Everything, for me, was seamless and fast and they did a great job. If you're going the whole route of solar and batteries, is recommend getting at least one expansion pack, maybe two, considering what your needs are. Just in the event it takes even longer for them to get powershare going. With a 3,000 sq/ft home and a 5 ton heat pump, I get about 5 hours with a single PW3 going down to 20%.

All I want is powershare to help back up my house during a blackout. No peak shaving or exporting. I'm like a ton of people with a fixed rate for power at all times so all that extra stuff does literally nothing for me. That is all powershare was initially marketed as and it's still all I want but Tesla still hasn't released the basics.

 

[Coolhandz]

I'm that case, all you need is this:

Tesla Powershare Home Backup Bundle https://shop.tesla.com/product/powershare-home-backup?sku=1841000-99-B

Will work right away. Plenty of Tesla certified installers in and around Boulder.

Options:
Get Powerwall based system and wait for Powershare to work with it
Get PW and add a generator switch to run part load from 14-50 plug
Stack Powershare Gateway after Powerwall
Get 11.5kW of non Powerwall solar on backed up side of PS GW. Can have more on non-backed up side

I had to take a step back and re-read your original post. So the Tesla rep is correct in canceling the order. From Tesla:

So they will not install a Powerwall 3 along with Powershare. It seems like your original order was asking for both which they cannot do and hence why they are saying it will need to be canceled.

As other have pointed out, this leaves you with two primary options if you want Powershare now.

1. Solar (and inverter)+ powershare gateway + wall connector
2. Powershare gateway + wall connector

There are other options, but less integration and automation.

Keeping in mind that the process for planning/permitting, installation availability, and grid approval can take 3 months or more, it might be worth it to consider just going with a powerwall 3. There are plenty of other incentives with Xcel that might make it worthwhile and it's just even more peace of mind. That is just my 2 cents though.

PS with PW is not going to happen. Tesla would at least know a reasonably accurate timeline if they could do it. They don’t and can’t. They still haven’t figured out how wipers work. It will be canceled much like the CT battery, MX and MS. The CT is being repurposed as a delivery vehicle. Tesla has no ROI on further R&D for the current CT.

Probably a minority opinion, but I think it's an either/or situation: if you have a nice solar installation, and Powerwall(s), I don't think that PowerShare adds anything to your capabilities that would be worth anywhere near the expense and complexity. And in the inverse to the above situation, I don't think that Powerwalls would add much to a good solar plus PowerShare and Gateway setup. Belt or suspenders, but not both.

(Sort of the inverse situation of just having Powerwalls, we have solar with net metering, and PowerShare and Gateway for our CT (which all together accepts any solar available when in its operation). We have virtual Time-of-Day pricing (in that the utility has a program to kick back 10 cents per kW), plus summer bonuses for never ever charging during peak periods...)

I think I must not be following you here. I have solar, 2 Powerwall 2s, and Tesla gateway to manage it all. I have Universal Wall Connector on the backed-up side, and of course my CT. (Note that I have 2 Powerwalls to have capability of backing up the entire house, including AC - one Powerwall did not give me the ability to run the AC during grid outages.). Once I get an over-the-air update to the CT and/or the gateway, I already have the hardware I need for PowerShare, I think (based on info from this forum and direct info from Tesla, if I understand correctly). The CT has the capacity of roughly 9 Powerwall 2s, so on a per kWh basis, it is much cheaper than the Powerwall 2 (or 3 or any of them). So once I have the OTA update, I can power my house for days, rather than hours, using the CT. I can also go to a Supercharger if needed to bring power home. This is obviously most valuable during extended outages, which is the situation I'd like to be able to use the CT for.
