Cable lengths (+ve/-ve) from bank buss to inverter
Time to replace my battery bank. Since Trojan L16s (and any other L16 or T105) are not available in Nicaragua at this time (and possibly never will be), I'm having to replace using Ritar Lead Carbon batteries (12V, 200 Ah). This means instead of two strings of 4 batteries I now have 4 strings of 2 batteries.
I will have the 4 series strings cabled to a common bus so that the negative/positive cable lengths from each string to their respective negative/positive buss are equal (see attached sketch).
My question - do the cables from the busses to the negative and positive terminals of the inverter also have to be equal in length (accounting for fusing, meter shunts, disconnect switches)? No problem either way. Just that the positive bus is a much shorter distance to the inverter than the negative and I would have a biggish coil of (possibly unecessary) cable on the positive side.
