how did you connect the solar inverter to limit the current to the grid?

I have an SMA-Sunny boy but I think it can only listen via modbus to the power generated by the sun (1-way communication)

He can't tell the SMA-Sunny boy to hold back.

I think you have a Fronius inverter, then I understand.
it is controlled via MODBUS,
Do you happen to know if I can limit another brand?
possibly connect the inverter to the AC1 output?

and which ABB inverter do you mean?
