The obvious answer is a cheap inverter ever few meters - this is typical practice with solar panels - and then a cheap transformer scattered around to get the voltage to whatever the line is. This is the common cheap practice for solar installs everywhere.
Microinverters where there is an inverter on every panel are also common - they are more expensive, but reduce some labor.
Either way the inverter is connected to a network and then get remote monitoring of each section and in turn can plan maintenance as needed.
