I sure hope so really looking forward to this super enhancement with hurricane season coming.

The Cybertruck battery added to the Powerwall in a virtual block, could help span across low solar production cloudy days providing power to the house during off peak and peaks hours 6am to 10pm

Resulting in a savings

Day 1 good solar day, covers day and fills the Powerwall, after 10pm, grid tops off the Powerwall and cybertruck
Day 2 bad solar day, running on the powerwall
Effectively off grid
Day 3 bad solar day, Powerwall sits at 10%, lets the Cybertruck carry house 95% down to 75%
Effectively off grid
Day 4, bad solar day, CT carries the house, down to 50%
Day 5, bad solar day, CT carries the house, CT down to 25%, 10Pm super off peak, grid charges back PW and cybertruck
Day 6 good solar day, cycle can repeat

Sad to say, "soon" in Tesla-speak means anywhere from a few weeks or months to several years.

With a grid connected 2021 system consisting of 12.25 kw of Tesla solar panels, 2 Powerwall+ units with separate inverters, a Gen3 wall connector and 2026 Cybertruck, I should be ready to go without additional hardware.
However, the devil is always in the details and so I'm at best, cautiously optimistic.

I've never doubted the things Tesla releases as fact, only the projected timelines. Things don't always execute according to their ideal timelines. I do think they probably gave themselves enough time to meet their current Powerwall/Powersharing goal of, what was it? End of summer or fall? I don't recall because I don't put a lot of stock in timelines that are fluid with whatever obstacles they encounter. I just think think this will happen before we get to the bitter end of the year.

I'll go public and say I installed a one Powerwall system this spring, I'm planning on making my Cybertruck the energy reserve (with no Gateway other than the Powerwall). If this software update happens, and I have little doubt it will, it's the cheapest way (by far) to get substantial battery storage that is seamlessly integrated with solar and that works during extended outages, even if you need to drive the Cybertruck to the nearest working Supercharger to top it off every few days (during unusually long outages). My goal is to have energy resiliency of heat, light, refrigeration and communications even though extended outages. As it is, the system provides that for a couple of days if care is used. Another potential benefit is to be able to share energy with the utility during peak demand periods (which I can already do if I sign up for current plans, but only with the 13.5 kWh that is in the Powerwall 3).

Right now I'm going to guess they release the update by September. It's a big job, and more complicated than most realize, because it has to work with all the major utilities and their various programs that utilities offer. It's not an insignificant amount of programming and testing. It also has to interface with other equipment like third party solar systems, etc. It also needs an unkown amount of certifications, etc. This is not child's play but if anyone can do it, I think Tesla can. They also have a lot of incentive because it will increase demand for Cybertruck which is a virtuous cycle. Meaning that as more Cybertrucks are on the road, there is a snowball effect. That's because the biggest thing holding back rapid adoption of the Cybertruck is that it's too unique. Normalizing them by putting more on the road will cause demand to snowball. I think that is the true nature of the Cybertruck. More of them in the wild will normalize them. Once it's not so uncommon and "weird" more people will buy the toughest and most capable electric truck ever made.

Isn’t the solar energy much more “dirty” and causes damage to the battery over time? Genuinely asking. Not FUD. From what I’ve read I’m not psyched about adding solar yet

Should post a link as to what you’re reading

From a logic and common sense perspective this makes no sense to me. How can your power walls discriminate power coming in from the grid or the power company? Power is power coming in at same voltage and frequency I don’t see how it can be “dirty” and wear down power wall any faster. If something was out of phase maybe, but all things being equal should be equally dirty.

Tesla already has proven solar and battery based inverter software and hardware. The bulk of the work should have been already done by Powerwall certification while on-grid and by Powershare approval while off-grid.

PW would still be the asset controller. Simplest implementation is PW telling CT what fixed power level (with protection limits) to export for the next X seconds with PW handling the rest.
Fancier is CT using that power level as its virtual power plant capacity so it automatically adjusts output based on local grid load.

Hopefully, the delay means they are doing a single release with all the features versus incremental releases. Though, the on-grid VPP trials are a stepping stone.
