Please confirm the function of the item you have listed as AP Systems ECU-C PLC interface. It looks like an ECU-3 with a wireless antenna on it, which would be just what I need,. I have 5 YC-500i microinverters installed, which I would like to connect to my LAN. I'd like to confirm that this device includes the ECU function, that it's compatible with YC-500i inverters (PLC communication), and that it includes wireless connectivity. Thanks!
