Try connecting via cable connection. Some solaredge firmware versions do not support Modbus over Wi-Fi.

This isn't a bug, your inverter is refusing the connection.

If you are trying to use other modbus integrations at the same time you have to remove them first: solaredge inverters only allow one connection.
