A grid with substantial solar or other DC generation can concentrate its conversion equipment in one location. That arrangement can reduce cost by keeping the equipment together. It also sacrifices some of the resilience of a distributed system. A major storm affecting the common site could therefore cause a much wider loss.

Centralized inverter equipment trades lower cost for concentrated outage risk
Grouping DC-to-AC conversion equipment can reduce cost while leaving more of a power system exposed to one disruptive event.
