There is not much out there on this topic, and Even though some of you have responded to individual questions
This document that was recommend opened my eyes as to wiring up battery's.
"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."
https://www.victronenergy.com/upload...ited-EN.pdf page19
So I thought to myself "Keith this should be simple - just get a buss bar" See what you all have done to me - I talking to myself
OK so lets make an assumption I will have 4 100AH battle born battery's at some point in time, Each is capable of 100 amp output - more for short periods. So in a parallel they would be capable of 400amp output plus up to 800 amp surge (30seconds). The battery's have built in protection so I don't need to fuse each one. Al this would be tied into a Multiplus 3000.
Some of you recommended this bus bar https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 however its only 250 amp rated and 20 amps per stud @ 12V (does not make sense as that only 80amps) . Maybe I am reading this wrong. While it probably has a safety factor of 2, the engineer in me wonders if the China engineers did that. Last thing I want is a fire below where we sleep. Spending a little more for a safety margin is worth the piece of mind.
There are 400 amp and 600 amp and higher bus bars out there $$$ but I want something with a cover. I have not found a covered 600 amp buss bar.I could probably fabricate covers.
But then I ran across this https://invertersrus.com/product/victron-lynx-power-in/ it is different that the distribution model in this thread https://gdrvowners.com/forum/solar/3...nx-distributor as it does not have the fuse connections or circuit board. Its 1000amp rated. Is this power in unit worth it?
Now there are other ways to wire the battery's (back to page 19) "Diagonally" but I Believe I would need to up size to 4/0 cables The Victron power in unit would only need 2/0 in (4/0 out) which are easier to work with. To keep current path equal, I would make sure all the battery leads were the same length. Correct?
So bottom line I have been looking at how folks have set up their systems, both here and elsewhere some with buss bars, others with just cables through a master fuse and switch.
So what bus bars are folks using and has anyone used the Victron power in block.
Thoughts / Abuse? all is good
Thanks again - still trying to learn as much as I can.
