One reason I choose 24v system is :
12v charge Victron controller (for 1,200w) charge controller and Victron
inverter/charge (3,000w) is about $1,000(with taxes) more expensive than 24v 's counterpart, not to mention the extra cost on wires etc.
While 24v to 12v converter is only one bucks.

But in any case, what kind of batteries are you considering. If you are ok with FLAs then 12V golf cart batteries are the cheapest $/kWhr.
