Hello.
I am comissioning my first bigger system and i ran into a strange issue.
System is located in Czech republic so i need to use individual phase regulation to archieve zero feed-in. But here i run into a problem. Grid offset seems to be tied still to total power so when there is unbalanced load and AC-Tied inverter is pushing same amount into all 3 phases it happens that one phase is running near zero and others have 1 and 2kw comming from the grid. (Grid offset set to 3kW) Issue is with power fluctuations it happens that it pushes some energy back to grid which can be a problem. (Distribution company is measuring it per phase and fees are 60 euros per kWh so pretty harsh). Is there some possibility to change this offset to per phase ?
I can be pulling 5kW from the grid no problem but i dont want to push anything to grid.
System : 12x Multiplus II 5000/48v and Solar Edge SE66.6k at AC-IN.
