V2H crickets

[Airnet]

It's been over a year since Rivian gave any updates on V2H ability. Seems like an easy feature to turn on and market. Do they need to redesign the wall mounted charger? What's the hold up?
Sure would be nice to have during the coming winter storms.

I know absolutely nothing offically from Rivian. With that said, they have their hands full trying get the R2 out the door. It's much more than redesigning the existing wall mounted charger. It will likely completely require replacing the wall mounted charger. V2H requires a device to convert ~400 VDC to 240 AC and requres an automatic transfer switch to disconnect from utlity. Depending on how Rivian designs it, you are likely looking at $5k to $10k installed. This is not a DIY install for the majority of the public.

It's not going to make a lot of money for Rivian, so don't expecit it to be a priority.

IIRC, the original V2H announcement said that an external DC->AC inverter was needed for Gen1, but Gen2 was just going to export via AC from the truck. I'm guessing they're waiting to see if an actual SAE spec comes out so that folks aren't locked into hardware for a specific vehicle. Even if you're looking at $5k-10k it's going to be a much wider set of people interested if that same hardware will be capable of being used with more than one vehicle.

The current wall charger is just a rebranded liteon one - I suspect they will likely do the same (contract out to an OEM) and just do the packaging.

The big hold up seems to be regulation, UL certification and standardization - virtually everyone has gone pretty quite; other than a few PR installs etc, is anyone shipping V2H?

I think that was R2 not gen2 - I remember thinking the same and then looking it up. Both generations of R1 look to have DC out capability (though I wonder if NACS changed that for the 2026 builds?).

V2H is only useful if you can disconnect export from the main panel when the power goes out. Can't do that without extra hardware.

I'd be more interested in allowing a third party inverter/charger to handle the V2H and ATS. Based on other posts showing the pointguard V2H and a Rivian, it looks like Rivian simply enabled bi-directional charging via software update. SO it appears that Rivian can enable this feature easily if the proper equipment and safeguards are in place.

Rebranding/OEM sourcing absolutely makes the most sense at this point .... but RJ has talked for years about vertical integration at Rivian, and my fuzzy memory seems to recall him mentioning this specifically about V2H, and I have seen past job openings for this type of engineer. Right now there is a posting at Rivian which includes some clues related to V2H that it might be in-house - see bolded items especially the underlined near the bottom - all clues, nothing more!

PG&E gave me a free transfer switch since I live in a high fire risk area (pretty much all of California) to use with my portable generator. Seems like it wouldn't be too hard to build an inverter that connects between the EVSE and the transfer switch. Heck, I wouldn't mind unplugging the car and plugging in the inverter to save cost. I'm sure some already exist but if they could leverage the common plug where I plug in my generator then it could be self installed and save a ton of money.

A 10KW inverter with up to 1000VDC input and 110/220VAC output can be found pretty reasonably. Just need to get the power out of the Rivian.

Reality check: R2 is volume seller. The company's future sustainability depends on it. While V2H is your personal pet peeve and want-list item, it is not essential to the companies survival. Once R2 launch and ramp is a success, and the company no longer burning the proverbial wick at both ends, then and only then can we hope to see more of our pet peeves addressed.

If you just can't wait, I believe the aftermarket is already starting to provide solutions. And it's even been discussed here in forums.

Agreed.

I am in no rush. I have an eco flow delta pro ultra inverter/battery backup and the eco flow smart home panel. It automatically switches to battery during an outage and I use a switching power supply to convert the 120v Rivian outlet to DC to re-charge my delta pro battery during long power outages. It works good enough for my needs until there is an affordable alternative solution.

If designing a V2H wall box while launching R2 would push Rivian into financial ruin, it's already over for the company. That wall box is low tech. People are already doing a DIY workaround.

An SAE standard sound like an educated opinion/reason. I found this article from SAE written 3 weeks ago.

Sell the car. Don't let the door hit you on the way out. People who have no experience running car companies shouldn't assume it's easy. Rivian is burning millions each quarter, trying to launch a new lower-cost car with broader appeal, expand service, AND add more RAN locations.

Childish to throw a tantrum just because daddy Rivian can't give you a V2H box now. Even parents have priorities to balance; doesn't mean they are bad or failing parents.

The lack of progress on V2L/H/G, at least in the US, was probably because everyone was waiting for a formal standard in order to provide a universal solution that would also facilitate smooth permitting and approvals; NEMA published such a standard, NEMA EVSE 40011-2024, on January 16, 2025. If people want to pay $129 then they can get it from NEMA's website
