Part of the argument for having multiple strings is for redundancy. If 
smaller interconnect cables are used, they will likely not have the 
required ampacity and OCPD to support the full load. In the event of 
part of the bank needing to be pulled offline there will be downtime and 
expense associated with upgrading the smaller interconnect cables to 
support the full load or the proportionally increased load.

Food for thought,
