Combining one source to multiple inverters
We have a large 80kW residential estate that has 5 separate electrical services which are to be fed with varying size PV systems. There will be a central array will be located in a field remote from all 5 buildings. Due to site constraints and util co. constraints we will be running very long DC lines to each building, where the inverters will be located, from the array field. We have to do directional drilling and run on poles, so we would like to combine at the array and send one set of source conductors from the array to each of the buildings then 'uncombine' or split source evenly and feed multiple identical 240VAC SMA inverters. Each building has a size different requirement, the largest being 30kW, then there's a 15kW, and a mix of other sizes. Basically, I'm trying to find a way not to have to run multiple conductors over great distances. Running AC to the array is out. Getting 3 phase is out. More details are I know, but you get the gist - my concern is that the mpp's will be at odds unless the inverters can be synched, but this is an area that we have not experienced before. Any advice is welcome.
