The reason is that this will reduce the current flowing through the busbars. To simply put it, the current entering the busbar from a solar charger can travel via a short path straight into the inverter or into a battery. This current does not need to travel through the entire busbar. It keeps the local "traffic" low.
If you have two sets of batteries connected in series, you can wire both sets into a parallel connection to make a series-parallel battery bank. In the images below we will walk you through the steps to …
Connecting battery through bus bar? | DIY Solar Power Forum
Is it okay to connect my solar charge controller, my inverter, and my battery to a bus bar? Most of the diagrams I see connect the charge controller and …
$begingroup$ @Kartman - Two +ve bus bars mainly because if they were on the one, the current rating would be around 640A and I wouldn''t know where to source a bus bar that can handle such ratings (in Australia). Will fuse between the +ve bus bar/s and the battery (however many there ends up being). Noted re: -ve bus bar. Will …
And a followup question. If I''m running to a real cupper busbar, then the cable that connects each battery to the busbar does not need to be sized for the max current (250-300Amps), but the busbar and the cables connecting them to the inverter do. The short cables that came with the battery are 6AWG. I think they can carry about 65 …

Let''s say you have a 8kW inverter and a 48V battery: 8000W/48V = 166A. Your busbar needs to be able to handle 166 Amps of current. We should multiply this by the safety factor of 125%. ... 166A * …
The humble busbar is one of the least glamorous components in an electric vehicle. But, metallic strips and bars in different sizes and complexities are essential for transmitting power from high-powered battery packs to motors and other devices. The most commonly used materials used for metal-stamped busbars are conductive alloys …
Current will always choose the path of least resistance. Most of the current will therefore travel through the bottom battery. And only a small amount of current will travel through the top battery. The correct way of connecting multiple batteries in parallel is to ensure that the total path of the current in and out of each battery is equal.
The cables and connectors transfer the current between the battery and the electrical components. The fuse acts as a protective device to prevent damage to the boat''s electrical system in case of a short circuit. The switch, as we will discuss in the next section, manages the power flow between the battery and electrical components ...

Busbar stacking wires question? | DIY Solar Power Forum
In my case, there is only one positive lead from the battery to the bus bar because there is a switch between the battery and the bus bar. The optimization of the wiring arrangement is probably only good for .001% better throughput. So don''t overthink it too much. Otherwise, your plan looks OK to me. Maybe put SCC#2 on the open stud.

Why You Should Use Buss Bars in your Multi Battery Installation
A bus bar is similar and calculated as to a solid piece of 4/0 wire, however, you can have multiple connection points along the bus bar and still have the circuit see it as a single point connection. What Battleborn is saying is with a sufficiently large wire gauge, connecting it to the middle of the battery bank, is electrically similar to a ...
