Doorbell 4 types?

I recently ordered a bundled pack from Amazon which included the ring doorbell 4 with the solar panel. I’m placing this camera at a location without nearby power. I have other cameras with the same setup. After opening this camera I see that there are the screws for hard wiring, but no plug-in for the solar panel. Yet it has a battery pack. I can’t find a difference on the website for the ring 4. Am I missing something? Is there part numbers? Cause it seems like they are all the same. And on Amazon it’s similar, ring 4 is a ring 4.
