Rivian V2X V2H Solution available now using PointGuard/Sigenergy BiDirectional?

This guy claims his 2025 R1S is outputting 11.4kw+.

We’ve been talking about this on the Rivian discord for a while now.

It’s very exciting and personally my only concern is Rivian sending an update to disable this until the time they choose to release their own hardware.

As someone with a large solar installation and batteries with a transfer switch, I want this to be available so badly. I’m tempted to add pointguard as a tertiary system just to get the V2H availability.

What we have here is a perfectly viable product - that proves that Rivian is just dragging their heels on making this happen.

Friend was using V2L adapter for Tesla that fried the charging port edit: Pyro fuse. Buyer beware. It was a different brand and they refunded the purchase price but not the repair costs.
Would love V2G/L, as well as better inverter capacity, 240v like the Lightning has.

No, what it proves is that the holdup isn't Rivian - the holdup is the availability of general-purpose, standards-compliant bi-directional chargers. Bi-directional chargers don't exist, outside some closed-system implementations (Ford's for instance, which works only with the Ford Lightning).

Big players like Enphase have been promising these for years, but they haven't materialized yet. Partly due to the lack of standards that would enable a bi-directional charger to work across all vehicle brands and models (subject to the vehicle supporting bi-directional charging). Ad hoc implementations have no future other than immediate convenience to a few.

When standards compliant bi-directional chargers (that integrate with solar, battery backup, and all models of vehicle that have the built-in hardware) become available, I will be among the first to get one installed. I'm already on the waiting list for several companies. But I'm not going to drop $10K+ to install some special-purpose solution that has no long-term viability.

Rivian's announcement of its own hardware was IMO an expression of frustration with the (lack of) progress these charger companies were making. Rivian has had hardware for bi-directional built into every vehicle it ever produced, with the ability to change the software control once the standards were established. Rivian has done its part, but the bi-directional charger market never materialized. Now Rivian is trying to spur the competition with its own hardware, but I don't think Rivian really wants to be in that business. Because frankly all the work and profit is in the integration - this can be done far more efficiently by some company like Enphase. I anticipate that when the Enphase etc. solutions start to become available, Rivian will drop its plans for its own bi-directional charger.

Until the OEM supports it I worry about the risk to not only the vehicle but the warranty.

This IS a compliant BiDi Charger, from PointGuard now Sigenergy.

IMO - the primary cause of the holdup has been the rushed NACS transition

This is great!

Any details on implementation with existing solar? I can't find anything on their site.

I agree with others that until a bidirectional charger is offered that works with a variety of cars and batteries, these will continue to be non-scaleable. This is an example where government agencies and regulations help consumers by forcing manufacturers to conform. Unfortunately, we will not have a standards based solution to this hodgepodge of options as the current climate is destruction of government agencies, not empowerment.

This IS the unit in the video OP linked

He has solar - and you can AC tie the system to any existing solar system as well.

As another upcoming option, EcoFlow has announced that their new Ocean Pro 400V system will support DC-coupled V2X bidi charging. https://www.reddit.com/r/EcoFlow_OCEAN/s/GHqv9yAmFP

We're in a shitty spot right now where we have to risk throwing money away or our warranty being voided.

Right now Rivian is the only truck maker to not offer V2H.

I’m TrueDad, posted the videos. I had existing solar, so the PG/Sigenergy was sort of seperate but I wanted to add more solar as well so I just did it all at once. So all of my panels now are on an Enphase system and it’s microinverters, but I wish it was all dc to take the most advantage of the PG system. So long story short, yes, it works with existing solar. No need to add or change what you have.

The Wallbox Quasar 2 can be ordered now within specific states and general availability towards the end of year most likely. Said to be supported by Kia EV9. Has anyone looked at their system? The EV9 is my backup plan if Tariffs continue next year.

Quasar 2

Thanks. Hoping to find schematics, tech pubs, etc. I've not installed one of these systems before, but I'm an EE, so I know it's both 1) well within my knowledge and 2) something I would totally f*ck up but want to research anyway.
