PowerShare with Powerwall UPDATE from Wes!

[mongo]

Exactly. This "dirty power" narrative reminds me of the people who used to cover their electric outlets so the electrons didn't spill out.

Question to clarify on the Powerwall update. Does this new software/Powerwall update mean that we'll be able to do at least power to home (and perhaps power to grid where allowed) without the installation of the Tesla Gateway? Will the current Powerwall 3 be sufficient?

Powershare Gateway (3V) is only needed for Powershare only setups.
If you have a Backup Switch or other version of Gateway, that is all that is needed.

"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). "

Please elaborate?

I have 3 power walls (part of the power plus program through my utility- no cost to me except that the utility can draw backup power from them if needed so it becomes a mini-grid - which is a good thing in case of wildfire or other disasters) and I got a gateway as part of my Foundation purchase. Can the Cybertruck use the Powerwall gateway? (and if that's the case what else do I need to get the Cybertruck as an additional backup to the power walls?

I'm far from an expert in this but my understanding is exactly that. But that doesn't mean every configuration will be supported. I'm guessing there are ways your system could have been designed that would require re-configuring it for the update to provide the desired functionality. Maybe @mongo has more input on this. The update hasn't been released yet so we really don't know all the details yet either.

We will know when the update is released but it sounds like @mongo has a better handle on the various possible configurations than I do. One thing that makes this complicated is the country/N. America is a big place and different utilities and regulators have different rules for what's allowable.

If I had to guess I would say the initial update will not work in every location with every configuration.

ChatGPT and Claude basically conclude inefficiencies with inverters or the carbon emissions from manufacturing as to the confusion.

That doesn't make any sense to me. My understanding of the claim was that solar was bad for battery health because it was somehow "dirty" electricity.

I think we can just write it off as manufactured FUD, designed to confuse and dissuade people from going solar/battery. In any case, not worth spending another minute of time on.

Dang I get excited every time I see a thread around this, but it's the same.
Made the same promises back in 2p24, and in 2025. I sure hope this is the year of they give up.

I've got an ar migration demand letter in route as this is ridiculous at this point. Value was sold as expected in 2024 but never came.

I’m pissed too, don’t get me wrong, I have a lot invested in both truck and powerwalls but the same promises were made by Ford who charged some people 18k for the sunrun setup and also did a presidential infomercial about it basically. Right after the “summit” on the electrification of American roads that included everyone but the number one producer and seller of American EV’s.
I’m yet to hear of a real world example where Ford’s system works well for someone though. Please correct me if I’m wrong.
And yet, for some reason I’m not seeing people crawling up Farley’s ass with lawsuit threats even though they have gone as far as discontinuing the lightning.
I just think as always that there is a bit of a double standard there.
Everything necessary to make this work is in place and I still have faith Tesla will deliver more than I ever had faith that others will.
It’s been unacceptably slow no doubt but nobody has said anything to the effect of this going the way of the range extender.

One of the primary reasons I ordered the El Cheapo CT is that it represents 7-8 Powerwalls. I currently produce more solar than I consume daily in Hawaii. My 3 Powerwalls get me through a day without sun. But with the CT "extender" I can get thru a week when a Hurricane passes…or the zombie apocalypse. I will be effectivley "off grid." Powershare can't come soon enough with our electric rates that woud make your eyes water.

YEP. Close to the same here in Colorado. New fires starting up daily and June/July never gets any rain.

Wait a minute, you're telling me that I made a mistake by covering all my household outlets to preserve electrons, for the last 10 years, was unnecessary?

Correct. Now you have to get those adapters to plug in which will sync the currents in your house and make everything operate more efficiently. Only $59.99 at select online retailers.

ireallyboughtoneofthese said:
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



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.

I think dirty comes for the electrical noise caused by the switching. I use my powerwall to shift peak loads to The night. Do pretty much runs every day. I used to work in a profession that used backup systems like the Powerwall and computers would reboot on switchover. Does nit happen at all with powerwall. Love it!

What electrical noise? I mean is there enough noise to degrade the battery in the Powerwall to any significant degree? I would think not. It sounds like made up BS without even a kernel of truth (like much BS actually has). The naysayers typically start with something that has a real component, and then turn it into something it's not. In this case, I think it's just pure BS from the start.

Yeah,
True Basis: crappy x-step modified sine wave inverters can overheat transformers, mess up switching converters, and overheat AC induction motors
False extension: this makes it through to an EV battery
