Has Anyone Installed the Enphase Gateway

Like title implies, has anyone installed the gateway for $700? My PVS5 is not functioning anymore so I have no way to monitor my system. Plus I have at least 2 non-functioning microinverters, which I am not sure if they are Enphase inverters or not as my system was installed early 2017.

Enphase stated they could determine the manufacturer after gateway installation. Not sure if I should ride it out and see what happens with Sunpower or get system fixed and operating 100%, as this is a cheaper option then the $6-10k quotes I have been getting to replace all inverters and monitoring system
