Charging Ecoflow Delta Pro Ultra with Rivian R1T outlet

[Forager]

@SeaGeo I completely agree on the EG4! Since the R1 can only output 1500W continuous, having an AC-DC converter designed for up to 5000W is overkill, and at $500 it seems unnecessary. I tried a quick search for a charger closer to 1500W and just didn’t find quite the right unit —what did you go with? It sounds like you run both AC-DC converters through the same R1 into the DC inputs on your jackets? I did found a couple e-bike chargers that had the right spec but the manufacturer was unknown to me.

I killed a 1200w one accident (TL;DR, the Jackery requests more power from a single DC pin that it should), so I sized up. But it also gave me some confidence that they won't randomly blow up on me. I've also run them for a decent amount of time without any issues so far.

I tried to find a MeanWell switchable charger, but just couldn't find the combination of DC voltage and power output that I wanted.

I have been planning on doing a write-up, but have just been too lazy. So here's a summary of what I plan on doing next time the power goes out, and why I went with a Costco package from Jackery on black Friday:

-Got the Jackery 2000 plus with the one auxiliary battery as it can output 3kw continuous and 6kw surge. I don't currently need 240v, so I wasn't too worried about it. The "head unit" is small enough that I can shove it in the truck and take camping if I want, unlike the Anker, and it was a hell of a lot less expensive and eligible for the tax credit with the bundle.

-Run the 120v outlets in the truck and run an extension cord to a power strip (fancy!). Plug two of the switching power supplies (get correct voltage) into the power strip. Connect the appropriately sized wires to the appropriate solar inputs.

-Use the R1T to keep the Jackery charged up.

- Prosper.

Sorry for reviving an old thread here. Ford is buying back our Lightning tomorrow and I will very much miss being able to power our home daily after charging for nearly free from midnight to 6 am. We had a Denali EV loaner for a weekend and it worked even better than the Lightning.

So if I was to buy the Costco EcoFlow Delta Pro 3 package from Costco (we need 240v) are you saying I can get 1,500 watts of charging input from the R1T bed plug using these DC power supplies?

You should be able to, but I haven't done it with an Ecoflow myself. It works with my Jackery though.

You will need to make sure that the power supplies match the input voltage range of the solar pins on the Ecoflow.

It is not a pretty solution, and is very DIY.

I own a Rivian R1T and Ecoflow Delta Pro Ultra. I am able to charge the Ecoflow with the Rivian outlet while at the same time using the Ecoflow to power things like the refrigerator, freezer, TV, router, etc. You do need to make sure you limit the Ecoflow input charge to less than 1500 W otherwise it may not work (at least that is what I had to do).

The Pro Ultra lets you because it has a separate inverter IIRC. Most share it with the A/C so you run into limitations like being unable to do 240v out or limiting output while charging on A/C.

Have you tried outputting 240v from the DPU while charging it with your R1T outlet? Just watched a YouTube video that said that the DPU has to have the switch in high voltage charging mode (to the left) to make this work. I think 1,800 watts would trip the R1T outlet.

To get 240V output you have to be in fast charge mode where you can’t limit the charge rate. I tried testing it and the power plug turned off. That’s why I went down the AC to DC power supply route as I need 240V to run everything in the house when the power is out.

edit: to fix accidental paste.

Floridian here with too much hurricane experience :

Delta Pro 3 - I manually connect to my panel to provide 240V
- It came with 400W solar panels which I drag out once the sun comes out while powering the house.
- When the sun goes down, using a 3 to 2 prong adapter and cutting down the charging watts on the DP3 ( <1500W), I can SIMULTANEOUSLY charge the DP3 with the R1T bed plug (120V) while sending 240V to my panel.

Warning! ***
With that said, please read RivianRocks25 scary experience here where this process damaged the Rivian's on board inverter while doing this. I will be rethinking my process now because of it.

Hope that helps!

That does help. Thanks. I wonder why it doesn't work for Ratchickens. Maybe he's on an older firmware?

Is the need to isolate the ground from the Rivian because the bonded neutral trips the truck's GFCI?

 

[tplociniak]

Latros is talking about using the delta pro 3, ratchickens is talking about the delta pro ultra, that’s why

I have the pro ultra as well and can confirm as well that his comments are correct for the function of that unit.

Be careful with the Delta Pro 3 and Rivian. I used a 2/3 prong adapter so had no ground loop. House connected at 240VAC to DP3 so powers well pump and other essential things. When house powers up, draws 2000+ watts and I erroneously didn't turn off nonessential for this test. When plugged 120 VAC input(set to 1200 watts in Ecoflo software) to Rivian outlet with this 2000+ watt load output from Ecoflo, the Rivian ac outlet turned on-off-on-off a couple times and then the RIVIAN INVERTER FAILED! Rivian had to drop the main battery and replace fuse and inverter! I'm SO scared to run the house while charging over AC at the same time now.

Looks like DP3 does 120v input -> 240v output pass though(that sucks) and can damage Rivian if power output is too great.

In an extended outage have main DP3 and 1 adder battery for 8kw storage that I keep charged to 70% for better battery life. I can run essentials for 24-36 hrs. After that, I would only charge the Ecoflo for 7 hours w/o any load at the same time, then unplug 120 from Rivian and run house. Sucks but best for Rivian. (also Ecoflo says have to cycle batteries every 3 months so we do that also.)

OR have to get a AC-DC powersupply to charge DP3 like this thread as DP3 shouldn't pass through then.

Be careful using the 120v input on the DP3 while powering house at 240vac off a Rivian R1S 2023 is all I can say.

Wow... thank you so much for sharing your experience. I will definitely change my recommendations and practices based on this.. editing my original post now.

Sorry to hear you had to go through that.

For those of you with Ultra's, can you charge the truck without being plugged into the house/ground?

I have had issue with my Delta Pro 3 not being able to power my 1500w RV AC while plugged into the Rivian outlet. I am wondering if I lower the input to say 400w or so , it would force the DP3 to power the RV with the battery and not attempt to passthrough the power directly from the Rivian
