Gotcha. I will inquire about the zigbee to gateway box since running ethernet to the inverters would be a nightmare. Did you ever look at the cost for it?I have the same screenless inverters and while they do create their own adhoc wifi network to configure the devices they actually do not allow you to join the inverter to a wifi network. Apparently in order to connect to a wifi network you need to get a solaredge zigbee to wifi gateway box. I don’t understand why the inverters don’t support wifi natively as they obviously have wifi hardware since that’s what they use for setup, but I spent quite some time trying to get my inverters to wifi and eventually realized that it’s not possible without additional hardware.
