Help with smart shunt connection

Hi I have a truma solar dual battery charger and the positive and negative both go into a 12v distribution box before then connecting to my two lesuire batteries in parallel. Am I correct in thinking that the shunt will connect to the negative coming out of the distribution box that goes to my first battery, then any other negatives from both batteries to the other side of the shunt and then finally all other positive connections connected to the second battery’s positive terminal to then go to the loads?

The rules are simple.

  1. The only connection to the battery bank negative terminal is the battery side of the shunt, absolutely nothing else.
  2. Everything else connects to the system / load side of the shunt.

Your shunt system side will connect to the distributon box. Both battery negatives wull be connected together. A single wire will connect from one battery to the battery side of the shunt. Both battery positive connected together, with the loads connected to the other battery.

Thanks for that it has now become clearer, the only other question I have is if it is safe to connect all the positive loads to one battery terminal as there are 4 separate positive leads. The connection to the battery is a terminal clamp that had a small flat bar with two screws in it that the leads connect to. Would it be OK to have two leads on each screw hole? Sorry if I’ve not explained it very well as not too sure on the terminology. Thanks.

If none are really heavy loads (1500W inverter) then you are OK, put the higher current underneath.

Ah one of them is a 1500w inverter, would that be a problem then?

Put the solar above that one as Solar never draws current.
