Wiring inverter into 4 x 6v bank (balanced)
I have 4x Trojan T125's wired up in a balanced setup (following previous instructions to that effect on this forum). I will be getting a 2000w pure sine inverter that I want to wire in, is there any p...

Have the inverter as close to the batteries as possible, but preferrably not IN with the batteries.
Use the thickest wires possible and fuse them (pos line(s)) close to the batteries.
I use two 1/0 wires per poles.
I used the POS pole of one battery group and the neg pole of the other.
I measured out the 4 wires to be equal length. (some say all four being equal is not as important) the multiple wires per pole MUST be equal length.
Keep the length as short as possible. 6' each pole will have a fair bit of voltage loss at higher amps. Use a voltage drop calculator and see if your happy with the results. **read the fine print on the calculator. The one i particularly like using does NOT want you to double the length of the wire runs. It takes that into account.**
It is perfectly safe to double up on wires per pole if you fuse them approprately. ie. If you are going to have 300a max to the inverter, and you are using 2 wires per pole, each should be fused no more than 150a or wire rating, whichever is LESS.
A fuse that has a higher rating than the wire, turns the wire into the fuse.
