Is it better to connect inverter directly to shunt or to bus bar? If so (or not) what cable size? Here is a diagram. I am figuring 1/0 which is 3X the 6 AWG connections at the bus if inverter is connected to shunt? Is this in the ballpark for how to set up? Going from no bus bars with 3 connections on battery #1 neg, battery #2 pos. Inverter is on battery #1 pos and battery #2 neg. (dealer install) Thanks in advance!
