Leisure battery drain

What's going on here then?

My set up is a 100ah SLA battery, charged by a VSR when on the move. Connected to it is a PMS3H which handles all of the mains etc. everything goes through a Victron Smart shunt with a temp sensor for the battery.

Also have a Victron 75/15MPPT connected which connects to a portable solar panel when I need to.

This ~0.1A drain seemed to appear out of nowhere as when I first did the upgrade to use the MPPT there didn't seem to be a problem - now I seem to be getting the constant-ish 0.1A drain which does seem to drain the battery when the van is parked for a while.

Any thoughts appreciated - would like to solve this before I start replacing the VSR with a DC-DC charger.
 
The shunt and mppt etc consum power... So there will always be a slight power draw.


Looks like the battery is staying above 12.0v after 7days.


You can see if it levels out or keeps dropping after 14days.
