Is there typically a fuse between the battery charger and the battery?

I made a brief stop at my boat today to discover the house bank was fully drained. My time was limited I was definitely on shore power and the Victron charger/inverter I installed last spring seemed to be working. Now, I'm trying to figure out what the issue might be before I have a chance to return to the boat and dive into it.

Any suggestions will be appreciated.

May you always have fair winds, following seas, and water under your keel,

do you have a parasitic draw?

If the main fuse was blown it wouldn't charge or draw down

suspect the issue is between charger and battery - OR, someone turned off the shore power

Don't forget about the battery isolator as a potential issue.
