Recently moved to AZ and am setting up a PV system. Can purchase 2 volt 1110 AH batteries for nearly same price as 6 volt 370 AH ones. Why wouldn’t I go with the higher AH batteries for my system?

That depends if you have enough PV to keep them charged properly..

RayK;

If you buy three 2 volt batteries and wire them in series you will have 6 volts at 1110 AH. Or you could buy three 6 volt batteries and wire them in parralel and you will have 6 volts at 1110 AH. So it is pretty much whatever you want to do….

Good Luck!

I have never seen a 6VDC inverter! How many thick cable connections do you want to make?($$$) How much room do you have?
