what does the term split system refer to? just curious . . . .

it's a system where the condensing unit is remotely mounted from the fan unit.

Thx for all the good ideas guys... keep em coming, rm

More than likely the ac manufacturer here will supply us the units set up to run on ac so we will just tie in the dc for the inverter and figure Out how to auto switch them to ac as soon as they are connected to an ac110v power source.
We will have to figure out the water cooled condensing aspect as the manufacturer only makes fridges and ac units for homes no marine related stuff as very few colombians have the coin to own a pleasure boat. Rm
