4/5G router Starlink replacement

We have a dish onboard our boat but I noticed we often have mobile service in Greece so would like to swap to a 5G router for web services and access to boat equipment via the victron energy Cerbo network when I'm away. I also have a Unify network connected to 2 cameras. What would be a compatible product? POE+ is a nice to have.

Must be robust since I cannot visit during winter to reset.

My preference is to supply power from our 12v battery bank (12-14.6v) charged by solar panels.

GL does not offer PoE supported products for the time being.

For 5G cellular routers, you can consider X3000 / XE3000, and it is 12V input.
