Ecoflow Delta 2 charging hack problem

How does the Ecoflow Delta 2 differentiate the source power when using the solar charge port (XT60i)?
If I attach a DIY 400W solar array to the Delta 2, it correctly shows charging from solar (see first two images).

I created a DIY solar power bank (third image) to provide supplemental charging to my Ecoflow Delta 2 via the solar charge port, using a 12v to 48v converter. In theory the converter will supply 480W of power at 48V and 10A, which is within the spec for the Delta 2 port which is 60V and 15A (and 500W max).
When connected and switched on, the Delta 2 initially shows a solar connection ramping up over 400W of solar (fourth image), before switching the input designator to DC charge, and knocking the input down to the max DC car charing limit of 8A, which in this case translates to around 378W at 48V (fifth image).

I have tried this with both an orange XT60i and a plain yellow XT60 connector with the same limit result. How does the Ecoflow Delta 2 know the kind of input source?

For your "fake solar" cord, are you positive (pardon the pun) that you have an XT60i cable?

From what I understand, the extra middle pin on the XT60i plug is what tells the Delta 2 if your input is car or solar.
 
You need a cable with the middle pin grounded to the negative, for the d2 to switch to solar input and remove the 8A/24V limits. The official ecoflow solar input cable would be guaranteed to work. I have several after market ones and several do not work as expected.

I do have what should be an XT60i. Thank you for the reply.

Hmm. But the standard XT60 (yellow) connector on my solar array works fine with it connected to the Delta 2. It correctly registers as solar input 333W in from the array. See first two pics from original post. I switch to the XT60i (orange), for the "fake solar" and it switches to the DC car charger limit. I have a genuine Ecoflow cable on the way. Will see if that makes any difference.

You can't go by visual appearance.

Here's all the ones I've got. the o rings ones def don't work will shutoff when connected to 48V. The elf club works but SAE so more connections. Also ecoflow has the polarities reversed from the common standard.

What I ended up with is these connected to my lynx distributor then a ecoflow and one other xt60i to mc4 cable. That way I can connect black to the positive bus and vice versa.

Interesting. Thanks. I will check the polarity on the Ecoflow input connector, though it still works with my setup, but just limits the input.
There is a video from Jasonoid where he connects a 48V EG4 rack battery to a Delta 2 Max in similar fashion and achieves the expected results, and says it works on the Delta 2 as well, but he does use the Ecoflow connector. That may be the difference here.

Thank you. The ElfCulb cable you listed worked!! The XT60i connector is visually no different from what I had, but the Elfculb cable works with the Ecoflow to take the power from my DIY converter (and then some). It draws more than the 480W, it draws the full max 500W the solar input is capable of handling, and shows the source as solar, instead of DC car charger. I think it is okay with the extra 20W and will not overwork the source system.
