    Jip, and I love the real-time status. At that moment the system was breaking even and the battery only received charging current when the fridges switched off. Wet towels over the fridges and parking in the shade helped quite a bit..

    That is seriously cool. I see those meters are sold by 4x4direct but wondered if it would not draw unnecessary power. I assume the switches you have there are to switch the meters on and off.

    Will the meter reduce the current supplied to and from the battery? I assume the meter has to be connected in line?

    Yes the switces are to switch off the meters when not required.
    The meters themselves have low consumption and I think the light in the switch itself draws more current.
    The meters all have shunts and are connected in line 'sort of'.
    It was quite a mission to safely wire up this system. The shunts are quite bulky. There may be other meters with less wiring required.

    You could also use watt meters
    really easy to setup , no shunts to fiddle with
    Pos and Neg in an out, also fairly accurate in my tests
