I am in Germany, I am using a Fronius energy meter on a three phase system with one Multiplus2 running an ESS with Pylontech batteries.
I have two questions concerning the phases used.
- Who defines what L1, L2 and L3 is in my system?
In my eyes, this is the energy meter that I am using. Whatever physical cable I connect to its L1 terminal will get reported as L1 in the system.
- I have my Multiplus2 connected to L2.
Is there a way to tell the ESS system that the MP2 is on L2?
I have found options for single phase inverters to be configured to L1, L2 or L3. But I cannot find such an option for the MP2 itself.
