Support for Fronius 3 phase inverter and Fronius 3 phase Smart Meter
Proposed changes are tested on Fronius Symo *.0-3 M inverter (highest possible firmware) with Smart Meter 63A-3, but there is also possibility to use only one of them (for example only inverter without Smart Meter).

Fronius API does not gives all information divided to 3 phases, so such data is attached to first phase (anyway, sum counts correctly).

you can move it above "if" and remove it from second if section

strcpy(buf, "GET /solar_api/v1/GetInverterRealtimeData.cgi?Scope=Device&DeviceID=");
strcat(buf, idBuf);
strcat(buf, "&DataCollection=3PInverterData HTTP/1.1");
pvClient.println(buf);
