While waiting for R2 and V2H

[SHRED]

I am very interested in vehicle to home considering I'm under the outrageous (investor owned) SDG&E rates from 4pm to 9pm at 80 cents per kwH plus I had an Enphase 5kw solar system installed in 2022.

I realize we're looking at next year potentially for V2H so I'm looking for a bridge until the V2H capable Enphase chargers hits the market and the R2 gets a firmware update to unlock it.

Could the portable charger be used with a 240V outlet in the meantime?

Rivian doesn't currently support any form of V2H (though they claim the hardware is present in Gen2+). So even if the mobile connector could backfeed your home (which I'm not sure it would even support electrically), the car just wouldn't do it.

If you're looking to be self-sufficient in the meantime, you'll probably need to install home batteries. That's probably a reasonable project even with V2H as the car wont always be there and wont always be charged. You could down-size the battery system knowing that you'll eventually have another 80kWh of capacity eventually, but I would not bank on that happening within any certain timeframe. If Rivian ever publicly abandons the V2H initiative or takes too long for your needs, you should be able to expand the home batteries pretty easily down the road.

I have a 10kWh Anker Solix X1 system installed and would love V2H as my batteries are usually depleted by bedtime if the AC is running (which in ATX it usually is). My old PV array wouldn't be able to fill too much more than 10-15kWh in a typical day anyway, which is why I didn't go bigger off the bat. But having an extra 80kWh for emergency backup would be amazing.

I'm finally get difficult to plan for v2h not knowing the time frames.

I agree with emroch that, absent OEM-provided V2H, having home batteries could be a good intermediate step. Be careful though - a lot of home backup batteries will not take 120V input (from your car) and do 240V output (to power your home) at the same time. And they often don't list that "feature" on their web site (in fact their wording may make it sound like it will work), so you may not discover it until there is a power outage.

My older Ecoflow batteries are this way. I tested to make sure they could power the house, and I tested to make sure I could charge them from my R1S...but didn't discover that I couldn't do both at the same time until there was an outage. See HERE for more details.

There are systems that will work as expected.

I think it likely we'll see V2L first as they've shown a V2L 120V adapter with the R2 powering their bougey RTT, but that will not be a 240V solution.

Read through the excellent post @mudito did on using your Rivian as a power bank using the current capabilities here:

Next EV that I buy must have V2H capability or it's a hard no. Rivian has the might to bring this to fruition, maybe spend less engineering time on electric bikes and more on what people really need. There are an ever increasing number of people facing power outages. Why don't they see this as the priority it is? This is really my only criticism of an unbelievable company

Bc it’s really not a priority for a lot of people. That being said all the hardware for V2L and V2H is in R2.

R2 has an 11kw dc->ac inverter onboard. You don't put serious hardware like that in there if you don't have plans.

I'm interested in seeing what they announce for V2H as well. I have a JuiceBox 40 J1772 charger right now. I was going to replace it with a Tesla NACS charger, but I think I'll hold off and use an adapter for now. And then maybe someday I can replace that with whatever their V2H solution is. I'm sure that will require a specific wall charger.

For those waiting for V2H, I would suggest keeping expectations in check until more information is available.

It's not an accident that the Ford/GM options that exist can involve $10k+ of electrical work to a house.

These systems involve a lot of big wires, main panel work, and safety considerations. Expect improvements to come at the pace of the electrical code, not at the pace of AI companies.

Does it? When I tried to confirm that a while back, I couldn’t find any official evidence, so I concluded that people might be mistaking an unclear statement about the level 2 ac->dc charging inverter (which, of course, all EVs have). That said, it might be that the charging inverter was designed to also operate in reverse.
