Hi All - I have reviewed a lot of post - but still have a Question regarding how to connect BMV-712 when you have 3 batteries (House, Port & Starboard Engines)
I have borrowed some images (thank you Rob Howdle https://community.victronenergy.com/users/1046/pjbfsc.html) to illustrate current system layout as per illustration #1 below
I believe this is the correct circuit as per Victron recommendation (and as per illustration A from another chat on this forum). However, I have the following questions - and would really appreciated some feedback - cheers;
Q1: Is illustration #1 the correct way to install BMV-712; or if I wanted to measure HOUSE then could i just go with illustration #2 ( and not use the Main DC Ground Buss)
Q2; I think I understand that the BMV-712 will only measure Load A and calculate State of Charge for HOUSE battery (thanks Paul B) https://community.victronenergy.com/users/1046/pjbfsc.html
But what about Load B/Engine Start PORT and Load C/Engine Start STBD; will this NOT be considered (or interfere with BMV-712 calcs) - what happens when I start PORT Engine; or run the fridge that is current Load B.
Q3: If I choose to connect Load B and C (other than Starting) to HOUSE, I assume I will need to definitely use the Main DC Ground Buss ?
