Get a bi-directional DC charger with a high power inverter (and solar) designed to power a home. My R1T's battery runs our whole house great with the Sigenergy DC bi-di. It seems like between the R1T's battery and a good amount of solar during long summer days we could be off grid all summer and still have wifi and air conditioner and cold beer and anything else we want running in the house.
Oh interesting, , someone says Franklin might be coming out with a bidi charger in the future. First party would be worth waiting for.
Is your R1T CCS or NACS? How does it "work" i.e., how does it tell the vehicle to drain DC off the charger, is there anything Rivian does to support it or is it part of the spec for the chargers to be bidirectional at a hardware level?
Unfortunately for me I believe Enphase doesn't work with any other company's equipment.Oh interesting, , someone says Franklin might be coming out with a bidi charger in the future. First party would be worth waiting for.
Sigenergy is interesting. Compelling to have a 25kW charge rate, and they claim they've done it in the US with R1T CCS (I have NACS, wonder if the adapter would work) and M3 (NACS). How does it convince the car to give up its electrons without automater support, though?

Yes. Check out their web site. Good information there.
I would be willing to make a large bet that Enphase starts selling their bidirectional charger long before Rivian does, since they have been consistent for the last few quarters saying it would start shipping 2nd half of this year. Of course that is after 2+ years of delays, but a lot of that was waiting for NEC codes to be updated which they are now. It will also require a meter collar, and every utility has to approve that meter collar first. They have a state by state list of utilities that have already approved it on their website. Mine hasn't yet. Considering Rivian's definition of coming soon is typically 1-2 years out and I haven't heard anything about it since that RJ interview last year, I would say the chance of Rivian's being released this year is about 0%. For me the choice was probably always going to be between Enphase and Rivian. Already having a full Enphase system made me lean towards Enphase anyway. I'm not expecting a very competitive price from either of these companies that have a reputation for luxury pricing.
That's my plan
I thought I replied to this but apparently I didn't. Sorry!
Roughly how much is this setup?
As I noted in reply to one of your other posts, the very same user (Youtube True_Dad) posted a later video that clarifies the Sigenergy system works "80%" of the time with his Rivian as a part of the system.
I talked to my Enphase system installer about a bunch of stuff last week. She was really positive on what Franklin is doing with their equipment. And she verified their home batteries are absolutely compatible with Enphase based equipment and her company has personally installed them. Apparently Franklin was founded by former Enphase employees. While they haven't announced anything about a bidi charger yet, she is sure they are working on one.
It is interesting that I have 100% success discharging my gen1 R1T through the SigEnergy DCFC. True_Dad and I have compared notes a bit and only one thing really stood out iirc. He’s concerned about battery chemistry so he doesn’t set his target Rivian-side SOC as high as I do. I tend to set it to 100% out of convenience when I am wanting discharge because that is always higher than my current SOC. But also it’s clearly not a requirement to target 100% because I also have only successes discharging also with a target lower than 100%. My tests point to the target just needing to be higher than current SOC so that the R1 does not ignore the available charger (which then requests discharge). But also his limit was very clearly a time bound not SOC and I have never hit any time bounds so there’s some other variable possibly. I have never had discharge stop prematurely versus my calculated intent and I always have it running hours on end (albeit slow-ish…8-12KW…can’t run the full 20KW+ from a 150KWH battery for that many hours). I have done this so many times I am quite confident I can run key household stuff through the night (HVAC, internet, fridges, L2 charging the Chevy Bolt
, recharge/run on solar during the day, and repeat indefinitely in the sunny half of the year.
