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

[KBabione]

Right, 3600 Watt inverter.

J1772 is AC only.

Here is an example 3600 watt inverter

That inverter is smaller (and much lighter) than my Bluetti AC180 that I use now to get me 1800W output. And thanks for the clarification...V2L is definitely what I'm looking for.

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.

Yeah agreed on all accounts, V2H is super overrated. All a bunch of $10k+ solutions and their proprietary for individual vehicles so might just need another 10k in 3 years. Requires major custom work to house electrical panels.

V2L with a $100 interlock is all that is needed and allows battery bank or generator or such to be swapped out with vehicle to power the house panel. Also can use camping or away from house!

Now since Rivian is exporting DC the box will need to be pretty big and expensive but if it was hopefully just $1k-2k and allowed full nema 14-50 (12kw) and could be taken on road or camping or such that would be awesome!!

I heard the R1 can only export DC so then it must use the larger CCS port instead of j1772?

That inverter is 24v and most the solar ones or vehicles ones are all 12v 24v 48v so it might be much more rare to find a 400v one.

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.

Why would the fuse blow?

Id think to work on high voltage could just pull fireman loop.

The R1 can charge over 500amps and likely more under full throttle so I wouldn't think the main fuse would blow but yes that would be a mess if it did.

Or you mean there's a small ~5-10 amp inverter fuse sealed in the pack? Yeah that would be a mess to replace.

There's an HV fuse just for the 120V inverter circuit, it's designed to protect the wiring to the inverter (as all fuses are). (It's only 10A I believe). It is in the battery case, since that's where Rivian does their HV distribution.

You can probably pull a little more energy through than what the inverter is rated for without blowing it, but automotive tends to size wiring exactly as required because of the cost and weight of everything.

A big, Portable? 12kw DC to AC inverter for $1-2K. In your dreams.

The internal options on EV’s like Ford Lightning is $3K.

And because it would be big, the market for it being portable Shrinks. So you either end up with V2H solutions (big inverter mounted on the wall of your home and a bunch of other components to make that safely work). Or you build it into the EV like Lightning did.

Portable that size just won’t be popular. Possible 3rd party solutions will pop up.

Yeah that makes sense your probably right.

Super wished we had a 240v 30a solution but it just sounds like that will be super unlikely.

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.

I was commenting on the expectation that each individual outlet should support 1500W vs that being the total combined output for all outlets. That's a different matter from the inverter only supporting 1500W instead of 1800W (or more as some had wished).

Sorry missed that it was a 24V one. Just try to get an idea on size.

I suspect a 400V 3600 watt-ish inverter will be big and unlikely portable. But it could certainly be done.

Main issue is what will make marketing sense.

In many ways I suspect it’s cheaper to put it in the EV (no connectors, no long cables, less safety issues etc.). Making it portable will be the most expensive option and probably the least demand.

I think an inverter in EV option is the best option. But it does not allow for V2H or V2G.

There are trade offs in every scenario.

 

[mswlogo]

If you have a 15A receptacle, it should be able to deliver 15A to whatever you plug into it with a 15A plug. Anything less is just setting you up for ill-timed disappointment and frustration.

Not really. A true 15A circuit is 1800 watts.

There are tons of applications that have “15A” plugs that cannot deliver close 1800 watts. The plug does not define the supported wattage behind it.

I carry an OUPES Mega 5 in the bed of my truck if I need significant remote power. At the time, I rationalized this as a possible “gas can” since it has a 5kWh battery if I need it. It’s big and bulky and like one of the other posters here, I can plug it into the truck to top back up if I need to.

6 months ago the utility company was digging down my street and cut the underground cable feeding our neighborhood leaving us with no power for about 24 hours.

Being able to leave the Mega 5 running in my garage with extension cords to two refrigerators, a chest freezer and the TV and router was nice. We could go out to dinner, public charge and then recharge the power station off the truck when we got back from dinner without ever interrupting the power to the appliances we were powering.

Ok you cost me a ton of $! After your recommendation and reresearching the hell out of the Mega 5 I realized I can let the Lightning go. I did love that truck but boy the wife loved the R1T Calif Dune and Rivian was offering $8k off to close them out. We bought one of the last ones. Then I ordered a Mega 5. No solar panels. Hoping the R1T will be able to recharge it.

I’m all in on replacing anything gas with electric. Wow the Mega 5 is way better than my old Honda I2000 generator! But boy is it heavy. Can’t pick it up to put in the bed. I could use my tractor but I’ll probably just hand truck it out to the green house when necessary. Definitely replaces the Lightning ProPower feature.

Next I wondered if the Mega 5 would run my Ego riding mower charger. Mower has four 10 amp hr and two 7.7 amp hr batteries. When the mower batteries level fell to 40% I used the Mega 5 to run the Ego charger. Did this twide and it worked great. I even concurrently ran a Porter Cable pancake compressor to top off all the vehicle tires in the garage while I was charging the mower.

Last but not least was testing the R1T power outlet to recharge the Mega 5. On paper it should work fine but it’s a pretty big battery. Again worked great! So much easier to set the timer and it just works. Started at 70% charge and ended at 67% battery charge. Took 2.5 hrs to recharge 40 to 100%

I’m very happy with my new truck. Wife named her Viv the Riv.

Thanks again for helping me make that final jump. I told the Rivian folks that they should have a couple of portable generators in the store to help seal the deal for folks like me. I would have bought one months ago.

Glad I could help! Welcome to the Rivian club!

It makes me think…

Imagine if the OEM’s like Rivian, Ford, Tesla, GM, etc went with a concept like this instead of building a beefy inverter directly into the truck.

Build a camp speaker style removable battery/inverter that fits somewhere on the truck. Make it so while it’s docked, it can either charge from the truck or do the reverse and charge the truck. When it’s off the truck, make it chargeable from a regular outlet or from a DC source like solar. Option different size AC inverters in it and add power outlets that can be used whether it’s docked or not.

Size would be a limiting factor. The bigger the battery, the bulkier/heavier the unit.

The cool part is functionally, most power stations on the market today can do everything listed above with varying degrees of success (except the purpose built car dock part ) for less than $2k.

 

[Cal]

I really like the ability to detach. So much more functional. No need to have it tied to a truck. You can drag it anywhere. Second floor, tight access, multiple rooms in a house, tons of options. Not sure I really want it riding around in my truck. Guess it’d be ok if it was light and it’s charge still contributed to my overall truck charge.

 

[technerd]

I will say, in a power out situation I was able to run 2 fridges & a freezer (plugged them in separately so the compressors didn't start at the same time), gas water heater, internet and lights/tv and occasional coffee maker, etc. It was enough for basic functions in an extended outage, but it's much nicer to have my Anker Solix automatic backup, I barely notice when the power goes out now.

VehicleToHome is coming “soon” (tm), right?

ASIDE: Rivian V2H support but this is in the works per an interview with their CEO (YT link) . Looks like it may be 20+ kW (240v 80a) too.
