The BMV needs set up for charging via solar,
You need to change the following , the default settings are OK for the rest.
Battery capacity, your actual capacity, 400
Charged voltage, the charge voltage your chargers are set to, minus 0.1 volt, example charge voltage 14.2, BMV setting 14.1
Puekert Exponent 1.05
Charge efficiency factor 99%
The shunt is connected as follows, nothing else is connected to the battery negative terminals (except in the case of other batteries negatives when connected in parallel). If the system has a negative buss bar, this connects to the shunt load output and every other system negative to the buss bar.
