Cybertruck needs to have vehicle to home charging (V2H)

[CyberJagg]

Here’s an automatic transfer switch.

There are many options for transfer switches. Auto/manual, surge/no surge. Get what best match your need

I have in my possession two beta two way chargers from a popular brand in solar. I can say with 100% certainty that it works with the F150 in a laboratory and is a simpler install than the Ford unit which is made by Siemens.
I know about what they will cost and the final versions are due out Q1 2024.
Tesla wants to sell powerwalls.
they have far less motivation to offer this than competing brands and equipment manufacturers.

I agree 100%. It was obvious a while back at one of the meetings. Someone asked Elon about V2H and Elon was stumbling to come up with a good reason NOT to have it. They want to sell Powerwalls at a huge profit. They don't want to cannibalize that side of the business. I'm with Crissa also. Look at the size of a Cybertruck battery just sitting there doing nothing while it's parked at your house. It could be used exactly like powerwalls as a virtual power plant, AND it holds 10x the energy! That is a solution for grid storage. It's got many uses, not just back-up energy!

Unfortunately SolarWizard is correct. Tesla stands to lose massive amounts of money if our Cybertrucks can be used that way.

There are integrated systems that automatically switch to vehivle power in event of outage, etc. Like the Ford HIS, these aren’t cheap, even assuming your breaker panel/service can accommodate.

Then there’s the 240v plug in the truck, which can be used the same was as a gas generator to provide power to a house. That can be super cheap (eg cords and break-out boxes), or a bit more spendy (eg a genny-plug, transfer switch, and critical load panel).

In either event, if you want an integrated/automatic system wait and see.

If you instead can settle on a reliable power generator for your home, the CT will have that in the form of its 240v outlet.

Yeah, mine is a set of cords I just swap from plugged into the grid, into the generator, leading to a special panel in the house.

Cheap, effective, not very automated...

It is true Tesla sells quite a few Powerwalls and does make money on them but it is NOT massive amounts of money.

Tesla makes much more profit using most batteries it has to build cars then Powerwalls.

The current Powerwall-2/Powerwall+ uses NCA/NMC type batteries. It will not be until Powerwall-3 is shipped that LFP is used.

From a design/architecture perspective I think Tesla strategy is correct that at least one Powerwall should be involved when doing VtH or VtG. The home should have at least a small battery (7-13 KwH) for when the vehicle is away from home to power critical loads like refrigerator/freezer, Internet router, sensors, monitoring systems, alarm systems and some climate control to keep temperatures from getting extremely low or high in some parts of the home.

I wonder what Energy Arbitrage profits will look like on the balance sheet in years to come. NFI

Could be a good earner at scale.

Lose what money? They currently can't supply the demand for Powerwalls. There's still a waitlist.

If you want something like Ford has where the home has a way to pull directly from the battery it will be VERY expensive, make the truck unusable as a vehicle while powering the house, and mean the feature won't be with you on the road so you can't power your RV or Worksite from it. Perhaps it will have 120/240v outlets AND access to V2x, but it would be the first Tesla to offer that, so I don't know that I would say TESLA NEEDS TO have it

The first Tesla Roadster did have V2X. If the Cybertruck does have V2X, it would not be the first Tesla to have such feature.

 

[Greshnab]

IMHO a stable solar solution for the home needs BOTH a car with V2X AND a house backup <power wall> the car acts as a second set of batteries for the house.. but the power wall is ESENTIAL to avoid a blackout when you use the car to get things like water.. ice...less forward thinking relatives.. etc.

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

Sure you can call it BS. There were even some early 2014 Model S with V2X technology built in. Here’s an article from 2018 about it. I wish I saved the early presentation of Tesla talking about V2X

You need to show your work. All I am finding is this: https://www.tesla.com/blog/smarter-charging

Tesla’s V2G Strategy

Test setup with VP10
Tesla’s initial approach to exploring V2G is to focus on ancillary services that can be performed with the vehicle operating as a grid-controlled load, rather than as a system capable of feeding power back to the grid.

The Now You Know Channel guys helped convince me about Tesla with their "It's the Super Chargers Stupid" episode. That is my goto reason I give to people who are interested in a BEV. Home charging is even more important and I have 12.4 kw solar and 2 powerwalls so my home and 2 Tesla's are essentially solar powered. In the summer months, more than half the power my solar system generates goes to the grid but thanks to the new net metering Regs, I am very poorly compensated for that energy.

If I could use my Tesla car batteries in addition to the powerwalls (bi-directional charging) I could be close to 100% self powered. The Tesla app could give me all the programming capability to allot power storage/usage,

Tesla needs to make bi-directional charging standard in all of their vehicles and I was happy to see this Thread discussion. Since Ford did this with the Lightning I'm hoping that the Cybertruck will allow same. It is the right thing to do ...

How would systems like this impact battery longevity? I wonder if they'll find some way for use to deplete battery warranty.
