Yes 48v is nicer but sure ups the costs of batteries - double of 24v  system .

I disagree.   If you require 8Kwh of storage, it needs about the same amount of lead, for both 24V or 48V systems.  The 48V bank can be half the Ah of the 24V bank,  which makes the cost of either bank, about the same per wh of storage.

Agreed

I only use 24Vdc for one system because it charges my MAN LIFT  Genie

As far as cost for 24v compared to 48v it all depends on the size cells you are going to use and  if you can find ones half the amp hour capacity for half the price so you can string together the same size battery pack.

Wow! Being a Total Noob it never occurred to me that 48v would require half the amp hours. Makes sense. And if I would have realized this I would have gone 48v, and for just about 30% more than my 4 435ah batteries at 24v, I could have gone 8  48 v and 265ah but more capacity ? Am see this correctly?

Yep
24V x 435AH = 10,440 W-H
48V x 265AH = 12,720 W-H
