Anybody Know What This Is?

[Sun Tzu]

I emailed Maxoak when I first saw this on the Bluetti AC100 and they never replied to my question. Anybody know what this "external interface" is supposed to do or what it's used for? Thanks in advance!

The manual says about this nothing?

It seems to be a port to make a firmware update, a diagnostic or something else like this.

It could be for connecting two AC100s together but, that's just a big guess.

From what I've seen and used of Poweroak products, wishful thinking about firmware updates by end users....most of power oaks products are tweaked reference designs from the power control chip sets used.
