As a result the battery was getting lower every day, with plenty of sun. OK so I would expect the re-bulk to start about 30 minutes earlier each day if the state of charge was dropping each day.
Didn't notice, not saying yes or no. With my very low draw any sun, even minutes before sunset, results in keeping the battery above 13.2. It has to drop below Float for at least a minute for Victron to start re-Bulk.
What I did notice was progressively lower pre-dawn voltage day after day, as witnessed both by checking voltage on the app before dawn, and Victron records of "minimum voltage" for each day.
