Hello I have 3KVa axpert inverter, with 2 x 240ah AGM omnipower batteries connected in series
I want to confirm if my BMV is connected correctly also if the settings is correct, please see attached screenshots

BMV Monitor setup
I think your charge voltage should be 27,3V (your system is 24V)
Personally I set the tailcurrent to 2%
@Gman which bmv do you have 702?
on the top Picture it looks ok .
But on de bottom picture there are 2 extra minus wires and 1 Extra plus
are you drawing also 12v from the same batteries?
If so that is not good/correct way
in this case the information given by the bmv is partialy correct(only the data from the rct)
beside that it will cause an inbalance on the battery’s
can you provide a drawing how and what is connected?
Please have a look at the below pdf

@Ray_mont Thank you, yes its connected like the diagram you given the exstra cables is a battery blanacer that i have installed recently will upload picture of that
My system is a 24v so my setting must be wrong on the BMV. I have the 712 with midpoint monitoring cables
