Solar cable plug / wall pass-thru

I have a small outhouse with a solar panel charging a battery that powers a Separett composting toilet and a few other things. Currently, the cable from the panel just goes in under the door, but I'd like to install something more permanent that I can easily disconnect. I'm having a hard time finding any kind of wall outlet for DC power—I'm imagining the equivalent of a weatherproof AC outlet box like I have outside my on-grid house. Any tips on what to use, or another way to do this I'm not thinking of?

Thanks,

Most DC connections use different size barrel plugs, so I use these guys for all my 12v stuff: MUYI 5 Kits 2 Pin Connector 18AWG Waterproof Wire Connector
And then you could use a box like this to house it: Sealproof 1-Gang Weatherproof In Use Outlet Cover

That makes sense. I was imagining MC4 connectors, but it doesn't matter what they are for this. Would you mount that cover on an electric box, or just use it as a weather cover over the hole the wire goes through? Anybody seen any kind of DC panel-mount connectors that would fit in something like that?  I get that I don't actually need it to be panel-mounted, but it could be nice.

Thanks again,

I used this cable entry for getting the solar cables into my van.

Interesting. Do you have to run the bare wire through and then terminate it with a connector after you run it through?

I didn't use a connector. I connected it directly the breaker/shutoff.
