At the moment nobody can tell me exactly what kind of energy meter (ET340 or EM24) I should use for phase compensation.
I have a Multiplus 48/5000 in island mode. The ESS would like to use the phase compensation and the connection to the public grid.
As far as I know, the ET340 is newer and measures all 3 phases individually. But there should be problems with this. In many forums the suggestion is made that one should switch to the EM24.
What's the right way now?
I would appreciate an expert statement.
