Looking for assistant

Looking for assistant than controls charge current depending on PV output from SMA Inverter on Modbus in Grid connected System. I have a Venus GX connected to a Multiplus and SMA inverter on AC input of Multiplus . SMA is integrated with the Venus and was hoping I could base the max charge current on a proportion of the Solar PV produced by the SMA . The ESS would be more elegant solution however connecting the SMA to the output means that the Anti Islanding of the grid connected system is not compliant with local regulations

Couldn't you just use an external current sensor on the multiplus?
