There are 4 batteries per bank hooked up with bussbars one positive and one negative, the shunt is in the negative side of the banks where do I connect the wire for midpoint voltage? The batteries are hooke up in series parallel in 2 banks of 4 each, they are joined by a positive and a negative bussbars and a cable from each bussbar pos and neg go to the all in one inverter. The shunt is in the negative side right before the negative bussbar, I understand that is supposed to go on the positive terminal closer to the negative bussbar? Or in other words from left to right left being the positive bussbar and right being the negative bussbar, the wire should go to battery number 4 on the positive terminal of that battery? What about the other battery bank? Will that work with the wire connected to just one battery on just one of the banks?
