Growatt Server: entity with same ids

I had a problem with growatt_server integration like this: Growatt Inverter not work.
So I solved it, copy and paste growatt_server component(from core src) into custom_componet and:

Now i have more entities with id:

  • energia_1
  • energia_2
  • energia_3
  • energia_n
  • tensione_1
  • tensione_2
  • tensione_n
  • power_1
  • power_2
  • power_n
  • etc…

How i can fix to get normal ids??
