Is the 120v 1500w limit for the entire truck or per outlet plug?

[KBabione]

Wow that would be great!! I’d buy one then

Right? RJ has said that all R1's have the ability to do V2H which means that the charge port is bi-directional. An external box like this would give us higher-amperage access to the big truck battery without the need to change our existing charger AND would be useful if we needed to take our trucks to a friend or relative who needs temporary power (or to a cabin, etc.).

I keep hoping that Rivian will come out with the equivalent to the Jeep Wrangler 4xe Power Box that would give us two real 15A outlets. I'd much prefer that to my Bluetti external battery.

I'd probably buy one, even though I don't have an immediate use for it, just in case.

Ok I’m really grasping for anything to buy this truck. I have a Lightning with the pro power system and run multiple rooms during winter power outages. Extension cords with power strips. Eg one strip to run my study: computer, Starlink, lights. Another extension for the living room strip to run TV, direct tv receiver. And a last extension to run the freezer. These are all connected concurrently but obviously not everything is drawing current at the same time.

The R1T has multiple outlets also. Is the 1500w limit a total for all outlets running at the same time or is this a singular limit? I’m considering each dual 120v outlet plug as one draw.

You really should get a generator back feed setup. It’s fairly cheap and simple.

You add one 240V breaker to your panel and you back feed it with a 30A outlet /cord. They sell interlocks for many panels that forces you to turn off the main to allow you to turn on the backfeed breaker. Like $100 of parts. Some panels are not compatible but many are.

Then when on backup you turn off the breakers you don’t need.

way safer than power strips and extension cords. You can run your furnace AC etc. And you can adjust as needed. Need hot water. Turn everything off and heat water for a hour.

You can add generator subpanels. But those are more restrictive and probably cost about the same as swapping out your existing panel if not compatible.

However you CAN do this with your lightning but you CANNOT with a Rivian.

I too want an excuse to buy a Rivian and Eying a Lightning.

V2H is excessively expensive and proprietary. You are talking $10K-ish installed. $7300 for just the parts from GM. Change brands and it’s another $10K

Almost every EV says they will have V2H. A few do now.

I get it and don't have a use case for true V2H. I referenced V2H only in the sense that it means that the existing charge port is bidirectional and current can be pulled from the battery. That's why the Wrangler Power Box is so appealing, especially if it had an inverter capable of giving us two 30-amp outlets that wouldn't trip unless the draw on either one exceeded 3,600W. I'm picturing the box turned on by a timer-like option on the Camping screen that would enable power to flow from the battery to the box for whatever duration you set.

Most, if not all, V2H setups have NO inverter in the EV. It’s DC back out into an external inverter. Doesn’t add much cost to the EV because it just uses the DC charging path in reverse. That’s what makes it expensive to make your H (the H in V2H) home support it. As well as a gateway (transfer switch) and a Wall Charger that can deal with AC in and DC back out to the inverter.

A lot folks think they will get 30A outlet on the end of a cord plugged into the charge port that supports V2H. That’s not how it works unfortunately. In theory they could easily have a portable inverter that plugs into a charge port. If there is a market for it.

And a 30A DC to AC inverter would be quite large.

Truck or power backup? Put a 15kw generator in the bed.

Okay - A guy can wish, can't he? I'd settle for two solid 15A outlets (1800W each):

Why would you expect that? Do you expect the same of the outlets in your home that are protected by a single breaker? If so, you must trip a lot of breakers.

All breakers in a house can deliver at least 15amps, unless it's a kitchen/etc than code requires 20amp minumum circuit... The Rivian is limited to 12 amps. It's so stupid as many small appliances will draw over 12 amps, maybe just for less than a minute, but my 135Kwh Rivian can't handle that. Meanwhile my 1kwh couple hundred dollar battery bank can do that.

 

[MacO512]

I wonder if anyone has tried replacing the stock Rivian inverter with an 1800 watt one? Not sure how smart the interface is between the R1 and inverter.... If it's just an on off switch then seems like it should be possible.

It's probably a 400v DC> 120v AC inverter.

I guess in theory maybe someone could put a 7200 watt one in its place. Either way would need custom work on "high voltage" 400v components.

Now electrical lineman consider everything below 600v to be "low voltage"

Does anyone know if this box is getting AC or DC from the vehicle? Sounds like R1 can only export DC. Maybe jeep is running the charger backwards to get AC into that box which would make the box able to be much simpler, smaller, and cheaper.

It looks too small to have an 1800watt inverter in it I suspect.

 

[MacO512]

1800 watts at 400v is less than 5 amps so I can't imagine the Rivian wiring would have any issues with that load.

Even a huge 7200 watt inverter (30amps at 240volts) would only need 18 amps which is less than standard outlet 12 gauge wire (20 amp circuits)

But yeah I kind of doubt all the Rivian computers would be ok with that high voltage 7200watt discharge without throwing a bunch of error codes. Would be a fun hack to experiment with once my R1 is out of warranty.

1800 watt inverter is only 17% bigger so seems like it might be an easy swap though at least in theory.

That’s an interesting option. Digging around a bit I believe the inverter has to be in the EV. J1772 is strictly AC. But news to me, it does have a Neutral. So I think it could produce 15A 240V Split phase (maybe). But that’s why you get two circuits out.

Great for camping etc.. But keep in mind that’s not V2H that many EV’s are boasting and someone mentioned is coming to R2’s. The Jeep box is technically V2L.

Using that concept that Jeep did is a bit messier on NACS. Only 1 circuit (without large external expensive components). And if 1 circuit, it would be 120V. And it’s not much value going above 15A (maybe 20A).

What doesn’t make sense is. Why not just put the Outlets in the EV?

I don’t know the electronics involved but I’m assuming they might be somehow adding hooks to the AC to DC charger inverter to run in reverse. Getting outlets powered in the car might add expense and failure points (relays etc.)

I personally want V2L 30A Split Phase like OP’s Lightning. And that can back feed a home.

Right, 3600 Watt inverter.

J1772 is AC only.

Here is an example 3600 watt inverter

The fuse for the inverter is inside the battery pack (It's 400VDC). On Gen 1, replacing a blown fuse means dropping the pack out. It's very difficult to open the pack and would require re-sealing it afterwards. Gen 2 has an access door to the fuses but I've not seen anyone investigate replacing it themselves. Perhaps I'll crawl under my Gen2 R1S later today and see exactly what that looks like.
