Eero Pro 7 Router Query

I've just been provided with a replacement router by my ISP - Eero Pro 7 - which doesnt apparentlyhave the provision for me to create a 2.4ghz SSID where my Gen2 inverter can live happpily on its own. My inverter didn't like my Nokia router and had to have its own SSID. I've easily reconnected it to my new router but I wondered if anyone has experience of Gen2 inverters being stable on Eero routers?

If your home router can't create 2.4GHz network, your options are:

1. Connect GivEnergy inverter by Ethernet cable (my AIO battery and Gateway inverter supports that, and that's what I am using to avoid any WiFi pains)
2. Buy cheap repeater/access point to create 2.4 GHz network.

Notes: you can use powerline adapter to provide ethernet connection.
