In a system with 2x3 MP2-5000 charging 90kW/h LiFePo by MPPT RS450 I like to add further capacity using AC coupled micro grid. Public grid is available but export to grid is not primary intention. In some Victron descriptions we find the recommendation for use of Fronius inverters because of its improved Victron compability.
Unfortunately, I ordered a SMA Sunny Tripower Core1 but SMA is not able to ship for almost one year and there is nothing in sight until summer next year. Further I am pissed on as simple accesoires like the integrated surge arrestors or sunny home manager now have double or triple price beside there is also nothing on stock.
I understand the reasons for the 1:1 rule and the required power regulation loop is done by frequency shifting of the Multiplus. Why is there any required GX communication by ethernet (Modbus-TCP) ? Only for visualisation ?
I hesitate to cancel my SMA assuming the Fronius stocks are also empty. But what are the benefits of Fronius against SMA or any other inverter brands in a Multiplus AC Microgrid ?
