I'm quite certain this is a stupid question, but I'd rather look stupid than destroy a Battery bank.
I'm currently wiring up a 3 string, 48V battery bank. Each battery is 6V. Now, I understand that three strings is not overly desirable, but this is the situation that I find myself in nonetheless.
The bank is located on a 3 tier shelf, with one string per tier. I'm running two inverters, and therefore require a total of 4 leads from the bank. In order to keep inefficiencies as low as possible, I will be taking the positive off of the nearest battery from the top string (roughly 4' cables), and the negative off of the farthest battery on the bottom string. Currently, the batteries are oriented as below:
+/- +/- +/- +/- +/- +/- +/- +/-
+/- +/- +/- +/- +/- +/- +/- +/-
+/- +/- +/- +/- +/- +/- +/- +/-
I'm unable to find a busbar heavy enough for my bank. In the way the batteries are currently oriented, the negative inverter leads would have 3 cable to one post (two inverter leads plus the parallel lead).
If I reverse one string's orientation (to -/+ -/+ etc) allowing me to maintain a maximum of 2 leads per post (while still maintaining 3 parallel strings, of course), will the polarity be effectively reversed on that string, compared to the other two?
