Using the above, 1280w x 12.8v =100AH, so he does plan on two "100AH" batts.
If his batts are really 120AH, then they are 1.536Kwh not 1.280
In any case, he has either 200AH usable or 160AH usable to compare with his 6s at 260AH usable (although you can go lower with 6s)
It is a contest between having a big enough bank to get through one day on solar vs having a bigger bank for a reserve in case of X days with no solar.
Adding more solar won't help if you already have enough for the one day and the smaller bank. Adding panels won't add to your reserve, and you don't need them to get through a day because you already have enough solar.

It is cringeworthy to say , "Two times less"! Gads. I think that is supposed to mean, "Half", but who knows? :(
