I have been looking at the exodus series prior to this. Do you know if you can do the same thing with those?

So the Oupes won't charge the external 48v as well? I just have an extra 48v 200ah that I was hoping to extend the capacity with.
It can charge/discharge via expansion battery port hack.

6 year warranty pushed me over the edge. Here's hoping they're still in business in 2032!

I think that doesn't work with the Exodus series which doesn't seem to have the chonky expansion port and lists 30v max solar input.

Hmm, I have been thinking of buying a Delta 2 to give my kid to have in her apartment, but this seems to be a better deal (the refurb delta 2 is the same price as this new unit).
I have only dealt with Ecoflow, so need to look into this a bit more.
OK, several reviews of it on youtube, biggest complaints I see is the oddball input cord (not the standard computer type plug, but not a huge deal), the app is a very basic app, and and it gets kind of loud at load, but then again, my Delta 2 gets loud as well (and will ramp up just sitting there sometimes).
Think I will grab one of these for her since she is not already invested in any particular brand.

I would definitely pay $299 for the Oupes as long as they will honor the warranty.
I have a Bluetti AC50S that is broken. I bought it in 2020. Bluetti told me they can't fix it even if I pay for it. They've moved on. They don't have the parts. That's the biggest issue that you will run into. Unlike with car parts, the manufacturer will have to keep parts around for 6 years. I find that highly unlikely. I would not be surprised if the "warranty" is them offering you X% off on a new unit. That is assuming they are still in business in 6 years.

I personally would rather buy an extra MPPT solar charge controller than try to hack the proprietary battery expanson cable.
Charge the 24/48V LiFePO4 battery via solar. Discharge it by connecting to the power station's solar input.
For a solar input that is 30V, use a 24V battery. It should work.

I've already got the 48v battery and was just hoping to find a way to leverage the battery as a ups/backup inside (so no solar).

Yeah, this is true, but a lot of these type items tend to fail within the first few month or last the warranty.
For $299, I will take the risk.
I will actually give my daughter my current Delta 2 that I know works, and then run this one through some use cases and if it is good, swap it back. My son will be moving out in a few months, so will give him the Delta 2 when he goes.
I don't really use the Delta2 much anymore since I got a whole house battery, so it just kind of sits around.

Trust is earned. I will believe in a 6 yr warranty when someone asks about it in 5.5 yrs ! That said, 30ish cents per Wh is the new "low" so.....

I am using a 24v 100ah (well, two 12.8v 100ah wired in series) with an XT60i cable on my River 3 Plus to charge at 220w (13a limit). For some reason, my Delta 2 will only go up to 200w (should be ~380 (15a x 25.6v), but only does 8a, not 15a, and yes, it is the XT60i cable, since it works just fine on the River 3 Plus).
Doing the "hack" allows bi-directional charge/discharge (well, on the Delta units it does, not sure about Oupes) and higher power transfer, using the Anderson port does not allow bi-directional power and is limited to 800w.

As above, you can use it, but through the Anderson plug is easier, but you will need a 48v charger to keep the external battery charged. The nice thing about the Oupes is it is 800w max through the solar port, so can recharge pretty quickly vs other units this size that usually are 500 watts max solar.

Sorry if I'm being dense, but Exodus IS an Opues as well, just a different line. It only has the solar plug, not the 4 pin expansion port.

I think the answer is that the solar port can only be input and requires the battery to be charged separately and would require the Exodus 2400 to use an external 48v battery. The Mega's expansion port supports input and output to recharge the external battery.

If you still have your time machine, this was a better deal. Someone had even supplied a code to knock off another 5%. Code may still work for this model.

Isn't that model still at $449? The coupon, "THESOLARLAB" still stacks to make it $426.55

You would need to buy a 48V LiFePO4 battery charger. Eco-Worthy makes one that is 48V @ 60A for $330.

If you want something less expensive, look at the Vatrer https://www.amazon.com/dp/B0FCXWH84H

You may be able to find others on Amazon.
