Wireless connection Inverter - smartmeter (Fronius)?

[courage2000]

Hello!
I want to install a PV system, but I have a problem.

I need to connect the Fronius Grid Smartmeter to the Fronius Inverter and I cannot use a cable for Modbus Connection.

Is there a way to use a wireless solution?

I have a Protoss PW-21, Modbus - TCP Wifi converter, for the smart meter, but how to send the info to the Inverter via Modbus-TCP?

The info must be received also via Modbus interface (RS485)
