R2 has bidirectional V2L / V2H (vehicle-to-home) specification article

[bigsky]

Doesn’t this only work if your average load is less than 1.5 kW? Topping up the battery while you are drawing will extend coverage but if the flow out is faster than the flow in eventually you run out.

Oh, no. Quite the contrary.
I purchased the Ecoflow Delta Pro Ultra Whole Home 18 kWh Power Solution; A/C inverter + 3 batteries. The maximum A/C inverter power output is 7.2 kW.

Circuit breaker panel powering my home critical loads has a NEMA L14-30P, your typical gas generator hookup. Maximum input power to breaker panel is also 7.2 kW, safety derated to 4.2 kW.
During an outage, my home power consumption is typically under 1 kWh the vast majority of the time; temporary 4 kWh spikes every now and then when some items in my home turn on.

The point being that most of the time, my home power consumption is much lower than the input charging power provided by my R1S, which makes my R1S the ideal solution for charging and keeping my battery solution fully charged forever with the R1S massive pack.

In the very unlikely event that I got close to depleting the R1S battery, I can always DCFC my R1S nearby; my home solution battery will have more than enough power storage to keep juicing up my home uninterrupted.

The only thing I had to do to allow my R1S to charge my home solution was to use an extension cord that floats ground, i.e., connection to my battery solution is H and N only through a dongle that removes ground pin/prong. Conversely, to charge either of my EVs, i just use another dongle plugged into the backup unit inverter outlet that fakes out ground. I then plug into it either the Rivian or Tesla mobile charger, voila!
It is awesome!

R2 has a capability for the onboard charger to output up to 11 kW AC

The other potential benefit for this 11 kW AC capability is that Rivian also have the option to provide much greater AC power for camping amongst other uses, if they make a high power outlet available in the R2. This is something the R1 and most other BEVs lack as they are often limited to 1.5 - 2.4kW max from an outlet.

So for those glamping with a microwave, dual induction hob, sous vide, electric kettle etc and wishing to keep warm with an electric heater, could potentially do so with all those appliances operating at the same time. Saves juggling what gets powered to avoid tripping a more limited outlet.

Could also use a high power outlet to charge another BEV in an emergency using a conventional portable charger.

Hi, care to share details of your dongles?!
I have a similar Jackery set up and was hoping to top-up charge as you describe from the Rivian, I was told by Jackery that this wouldn't work due to a floating ground, is it really just a case of using plugs that have the right amount of pins?
Thanks for help.

Another problem with NACS, there's no neutral, just like J1772. You have to choose to export 120V or 240V and can't do both. Really curious how Rivian intends on handling this for Load exports. You would need an external transformer to be able to do 120 and 240V.

R2 has a capability for the onboard charger to output up to 11 kW AC

R1 has the ability to output approximately 22 kW DC out from the battery directly to an external inverter that would then convert to AC.

None of this is new. None of this is news. This is just a rehashed story for investors and marketing. This is basically Rivian stating the R2 will have V2L capability.

V2H is good news for those of us who could not use this feature because Tesla wanted to sell us Powerwalls instead of allowing us to use the much larger battery under our vehicle. Now that I have solar and battery I don't know how valuable Rivian V2H will be for me, unless it is virtually free to connect. Ideally it could replace the gas / propane generator taking up space in my garage!

If it has the forest edge interior with the compass yellow and bright ATs
A rare

Am not knowledgeable about the options - Rivian describes it as:

Compass Yellow exterior color

Ocean Coast + Dark Ash Wood interior

20" All-Terrain Bright wheel and tire

It seems logical for Rivian to default to exporting 240V via NACS but like Ford's Pro Power on the F-150 Lightning (9.6kW output) they could support 120V and 240V from multiple 120V/20A outlets and one 240V/30A outlet inside the vehicle. The wall charger could derive the 120V for home loads.

Emporia Energy here in Denver has committed to making a bidirectional charger that by report will work seamlessly with Powerwalls. Rumors are that they are trying to keep it in the $2500 range. Since they show pictures on their website of their excellent L2 chargers working with a Rivian, I assume the Bidi charger will also (ie Gen 1). Added advantage that if you have Emporia Vue energy monitoring, you can use smart metering to keep maximal usage of charger + home under the limits of your service.

You know, another concept here no one has mentioned: If it is relatively easy / low cost to set up the R2 as a home back-up, and someone is a low mileage owner, maybe retired, work-from-home, etc then it would be trivial to switch your electricity plan to a time-of-day arrangement that many utilities offer. You charge the car at night at half cost or more, and then run your home off the car battery during the day. Even with some efficiency losses, you could probably save 1 or 2 thousand dollars a year depending on home usage. The impact on battery longevity wouldn't be worse than if the car was driven more often anyway. Feel free to poke holes in this idea, but it seems legit to me.

As a retiree this has been a long term plan for when I go solar/small home battery/heat pump/V2x. Posted about it here

We agree, this was my point. The home battery is buffering spikes above what the Riv can output. The Riv charges the home battery. It works if your average home use rate is less than the Riv output rate for long outages (in this case 1500 ish watts) and if you keep enough buffer in the battery.

I think our average use is higher than that but that also includes charging. Interesting set up.

Would have been 3 discontinued options rolled into one vehicle

Exactly. The safety-derated power rating of my home breaker panel powering the critical loads is 4.8 kW. The max. output of my storage battery is 7.2 kW. We know that our homes do not constantly run at max. load.

My home power usage is typically less than 1 kWh most of the time. Total daily usage is 18 kWh lately. This means that my battery storage would get depleted in one day worst case. But that is not typical. Instead, runtime shown on the unit display during last outage was several days.

1.5 kW output of my Rivian charging by battery solution is more than sufficient to keep it fully charged always. For weeks on end, if needed.

Absolutely, been following that thread. My plan is to "retire" my R1S to home back-up and occasional use after 250,000+ miles (70k currently). I am sure bi-directional for the R1S will be available then, and I could have the R3X for my daily. No rush, though.
