Glenn: I asked Enphase if I could run IQ7+ inverters without a gateway and got conflicting answers. I tried it and the result I got was the inverters would run briefly without a gateway and then shut down. Apparently we needed the gateway to load in a grid profile to the inverters.
Once the client bought the gateway and we loaded the profile there was no reason to remove the gateway. Therefore I don’t know if you need the gateway to remain in place. Hope this helps.
