Victron smart solar connected to bat and solar

[simonfraser]

Showing 13.80 battery voltage on the app
actually 12.80 on the Victron and battery terminals
eh ?
not connected to shore
drops a little to 13.78 and then shows - 0.10 A

is that normal for a Victron SS ?
the gel bats are basically full ….

Unless you have a smart battery sense the solar charger cannot adjust for the voltage loss between it and the battery hence your scenario.
