WIRING manual selector from MPPT to charge 2 battery banks and another selector to power inverter

i dont have a boat or rv and i ve tried a controller that charges 2 battery with no success. so, im thinking the victron PWM duo would be the same since its meant to be for boats/rvs.

my problem atm is the power runs short by a couple of hrs to my requirements. the easiest solution is to buy bigger batteries but i have these FREE BATTERIES. i also have no problem on the panel/charging side.

my question is possible/safe to install these manual selectors remembering to isolate panels before any switch?

thanks for any input...victron.png

Why not run all the batteries in parallel? Even if there are 2 different capacities, if the make and the chemistry are the same, then the voltage requirements are identical.
