Hi All
We have a 12v house bank (4x6v in Series-Parallel).
It was setup by PO, and as far as I can trace the wires looks like in the picture below.
I understand why on occasion you might want to draw from the house banks separately, (OFF/1/2/BOTH switch) but I see some downsides:
1. The
charging bus bar and OFF/1/2/BOTH switch is a few meters away from the batt compartment and also away my BMV712 shunt - this is a pain because the +ve sense wire is only connected to one pair of
batteries.
2. I want to install a
inverter - that too needs to be connected to the house bank as a whole - again this has to be somewhere after the BOTH part of the switch?
I am thinking I will change to a ON/OFF switch for house and joining the positive terminals in the
battery compartment with one cable to the ON/OFF switch. Thoughts?
I am also thinking that the start batt and house are different chemistries - not sure why they share a
charging bus and I will isolate
motor inverter to start batt.
