That is rack mount, the other is wall mount.
Many inverters come in a box with a screen and 4 buttons setup either wall mount or rack mount
Pictures mean next to nothing is what i was trying to point out
Saying this is what axpert kings looks like is problematic
At best you can say this is what company x implementation of axpert king looks like
Pretty sure you will find their axpert could look exactly the same, companies like reusing certain items to save costs
ie the case the screen etc
Take the synerji as an example
I know of at least 3 5000w models that look exactly like mine
ie you get an off grid one (self explanatory no grid tie)
Hybrid (grid tie)
And a model that has a pwm instead of mppt
That's just the 5kw models
Other models use the same case
3kw 4kw
With 24v 48v sub variants on some
I could not get a manual for my specific model ,suppose if i keep going i will
I stopped when i got a 3kw model with the same grid tie, ,mppt and menu setup
Cause that was all i needed guidance on what each menu item represents
