That is what mine looks like (installed in March) though I have seen what seems like a different version - no idea if it is just cosmetic or something else. (I was kind of annoyed that the Solar Gateway does not seem to come with mounting hardware or even a couple holes to hang it off of some screws/nails.)
I thought the exact same thing. I think I’ll use command strips or something like that to attach it to the wall near the inverter.
