Connecting 4 - 12v 100ah batteries for a 24v Inverter

[houts]

I've purchased four 12v 100ah AGM batteries.
Are the diagrams below correct to set up four in 2S2P for my 24v inverter? It should be 24v with 200ah.

Also, I have 2WG battery cables. When I connect from one 12v battery to another, do I use a red or black wire? Does it matter?


Solar panels x 4 (used): SST-240-60P Brand : Trina Solar Wattage : 240 Watts Voltage : 37.2V ( open current )
Batteries x 4: Weize 12V 100AH Deep Cycle AGM SLA VRLA Battery
