The short answer
Yes, check PLC noise detection in the Installer App; move noisy devices, relocate the gateway or use filters or a dedicated circuit.
Plain explanation
From the Enphase manual for the IQ Gateway + micros: Installer App > Devices > IQ Gateway > Powerline Communication Noise Detection. Remove power strips/GFI/dimmers near gateway. The rest of the checklist is below; work through it in order. Installer only: DC and AC work on a live PV system is dangerous, so owners should note the code and call their installer.
