Though this is not a site for these type of questions and I am not familiar with the equipment.
However check to see if the mini-splits are single phase or three phase. Single phase is typical for most residences and will work with both single and three phase service of the voltages within those ranges. Three phase will only work with three phase systems or some extra electronics and or hardware to create three phase from the single phase. Also often the three phase device cots more (because of advantages not mentioned in here that are negated whenever installed through additional equipment to a single phase system).
Anyway, I recommend that you hire a HVAC contractor for the installation of a mini split system.
