From the machine where is installed HA I can get access to 192.168.30.8

Same here. I'm using port 502 but the error log shows 1502.

Are you connecting to your SolarEdge inverter over the Wi-Fi interface?

ModbusTCP over wifi appears to be no longer supported with new firmware versions.

Have a look at #67

kazek127 commented 2 years ago

yes, that is correct. I call to SE support and they after update inverter block that option via wifi :/

pepsonEL commented 2 years ago

Yes in new FW modbus over WIFI was blocked.

I asked solaredge to downgrade the firmware if SE4000 inverter to 4.12.35 and modbus over wifi now works !
