2kw Inverter + 4 GC2 6v batteries = wiring???

I now have 4- 6volt GC2 215 batteries, PD9270 converter charger, and and a ProSine 1800 watt inverter (2800 watt surge) and want to start wiring.

I have a quantity of 2 AWG wire on a spool, a supply of tin clad copper wire ends in various sizes, and a heavy terminal "hammer spike crimper thing"

I would like to add a battery turn off and shunt to measure amps and also be able to measure voltage/charge remaining.

So here's the setup.

1. Four batteries in a row, long sides against each other. Call them A, B, C, D. A&B pair #1, C&D pair #2

2. Two 2 AWG cables for each section to allow higher amps. Ex. two 2 AWG cables between battery A(-) and B(+), and two 2 AWG cables between battery C(-) and D(+), and two 2 AWG cables between B(-) and C(+) to make two sets of series then paralleled together to get 12v "super battery" LOL

3. Two 2 AWG cables from D(-) to one end of shunt and then two 2 AWG cables from other end of shunt to inverter (switch, then (-)) and PD9270 (-)

4. Two 2 AWG cables from A(+) to inverter (+) and PD9270(+)

5. 120v AC line to distribution box (30 amp transfer switch?) and PD9270

It's a little foggy, so I'll stop there and ask for input ;)

Wire size, wiring diagram, etc.

Caveat, the PS1800 has built in transfer switch, but I prefer not to use it. Want to keep a separate circuit and/or transfer switch at the 30 amp 120v incoming cable for pedestal/generator.

Help? ;)
