OK, I just read thru the entire Wikipedia article and I am not seeing ANY reference to this. Additionally if they did provide power DC power out why didn't they provide DC power in? You can only charge the original Roadster via up to 70a 240v AC w/o hacking your car. Calling BS
It didn't do DC out. It did AC out.

Not alot of people with sports cars need that as their backup power sources - they're the sorts that have on-demand generators and such.

How would systems like this impact battery longevity? I wonder if they'll find some way for use to deplete battery warranty.
Depends on how it's used. Battery cycles are counted independently in the logs anyhow, so it wouldn't be all that difficult to count. Generally backup systems are rated in years, not cycles. They're used infrequently, so it's not a big use... and an EV contains like three days worth of the average household's power.

As grid-tied storage, you'd use only 20% of the battery, so as to not impact the availability of the vehicle to the user. And so, wouldn't do much in the way of wear to the battery.

So it did V2L? Did it have an inverter in the cigarette lighter? Did it use the charger as an inverter? I am not finding any info about this online.

You need that for any backup system, vehicle or no. It comes on every UPS and backup power brick, it's not like a complex part.

And sure, you have reliable power. But most rural buyers don't. Texans don't. Californians don't. People in hurricane and bomb-cyclone areas don't. People in wildfire regions don't. You know, places where it's handy to have a truck.

This is why I want V2H from the Cybertruck, I live near Fort Lauderdale(Hurricane country) ?.

Correction Cybertruck does not need Vehicle to Home. It needs Vehicle to Load, and your home needs equipment that can seamlessly accept that V2L power. That same V2L in port can also use a fossil generator (ducks to avoid thrown rotten tomatoes), or a portable solar trailer, or your friend's EV, or or or or...

Tesla is NOT the only game in town for this, and Powerwalls are not the only, let alone the best power storage solution. Yes they have a slick app and integration and in some markets do the energy arbitrage for you.

Yes V2L based backup gets way better if your home has at least one overnight of fixed storage battery too, and solar on top of that. But the minimum viable feature to put into the CT is 240V V2L with decent amps out.

Mostly agree but It's way more than a slick App. It is the very same App that manages the vehicles and solar systems. It is a tool that has tremendous flexibility and gives accurate reports on home, vehicle, grid energy usage. That "slick app" is more important than any claimed advantage by other power storage solutions.

As usual, Tesla is venerable to marketing hype as opposed to any factual comparison because they don't spend anything on advertising/marketing. Legacy Auto, the Energy sector, media and advertising/marketing companies hate Tesla because they are doing just about everything better. Am I a fan boy? you bet I am and I support them with my wallet as well as with words. When they make an HVAC system for the home, I'm buying into that as well and I don't give a rats ass about Elons latest Tweet. :)

What Cybretruck really needs is V2V, so that we can rescue all those F-150's found dead on the side of the road

IIRC the Model 3 and Model Y, at least, do not have some physical component necessary to output power like in a VTG situation. It was bi-directional diodes or something... It didn't sound that expensive but there was an illustrated parts breakdown and electrical schematic that I remember geeking out over. Anyway, someone explained why you couldn't send power backwards through the system. That could be easily changed by Tesla to allow for V2G with the Cybertruck, but we haven't seen anything official about it at this point, have we?

I believe Telsa/Elon is making a strategic mistake by not making their vehicle's V2G/H (whichever is the correct acronym here) compatible. Do we actually know the hardware is there in the car to support with a software update? I know further hardware is needed on the house side, but the vehicles, all of them, should be capable.

Making your product worse in order to protect a market for your other products is the wrong choice IMO. Make the product better and sell more vehicles, if it's better for your customers than powerwalls, then do it. If you don't, you leave yourself open to be disrupted by a competitor who has no such limitations. If the powerwall is better, than it will win. Perhaps, the combination of both is best, but I would be surprised if powerwalls end up in as many homes as quickly as the vehicles will. I would imagine that for some time, more people cannot afford both.

Lastly, I like to think about this at a civilization level. After all, from the perspective of our civilization, Tesla's profitability for a few years is rather unimportant. So what sort of civilization do I want to live in? I rather like the idea of one in which hundreds of millions of EV batteries are used to provide a stable, resilient grid rather than sitting there doing nothing most of the time. I like the idea of that kind of efficiency, and it could do it far faster than powerwalls will, simply because people will prioritize a vehicle purchase over a backup battery. No more Texas heat waves killing people, no more long outages in NYC due to a Canadian power hiccup (anyone remember that one, I might be misremembering the exact cause).

This idea that V2H is bad because, what if you need the car? That's just obfuscation, if I have no backup power at all, then what does it matter? At least with a vehicle, I have a the choice. When I'm home, I have power for the fridge, A/C, wifi. When I leave the house, I don't need the A/C and wifi and the fridge will stay cool for some time. If I'm prepared I have have filled the freezer with water bottles and then distribute them throughout the fridge, maybe I've picked up some dry ice as well. Who is going out all the time during a power outage anyway? If it's a hurricane, the most I'm doing it going to get water/supplies from where FEMA is distributing them (or hopefully I have my own, where else am I going?). Or I'm getting the hell out of dodge in which case, who needs backup power? Personally I think Elon is full of BS on this one, he's thinking like an old/traditional company that has an established market to protect.

Disappointing.

folks also shouldn't incorrectly assume that V2H means you can power all of your home just because the V is plugged into the H

there will be load limits. many homes exceed those load limits when running 'normally' (if only in spikes, but spikes are the ceiling)

it's in effect a critical load panel, with that critical load dictated by the limits of the vehicles max output

And a fierce competitor it is. If only Ford could figure out a way to not lose $60K on every BEV they sell. Now I'm not an accountant, but that doesn't seem like a formula for success. They must really love their customers ...
i think it is funny as heck that EVERY electric vehicle out there is trying to compete with tesla and tesla doesn't compete with them at all.. they are only trying to beat the ice vehicles...
