Multiple node 200units integration

Hello?

Solar inverter locates several sites about 10 field.
each site has 20 inverters.
so totally 10 emonpi , 200 emontx .
and want to manage one emoncms user account.
anybody can advise me node number allocation ?

I ve found the way by setting nodeoffset = 3200
one more thing is node name would be easier by setting to remote emonHUB.
