Because I'm lazy and hope someone else has done the analysis I'll ask first;
What are the economics of utilizing a DC combiner box at the array, and running a 2 wire DC circuit (2//#4/0AWG) to the inverter from the combiner box using a larger Inverter say 166KW, versus utilizing smaller inverters (3 x 50KW) with built in string connection capability (SMA) and running ckt as #1AWG, 3ph AC circuit from each inverter to power panel?
There as equipment cost considerations but also installation and labor cost that need to be factored.
Thanks
