IQ8-BAT curiosity

WebPower

Hi. 

So I bought a "open box" IQ8-BAT microinverter off ebay. I've confirmed its new and never been provisioned.

Problem is, I tried to provision and get it to operate but haven't yet been able to get it to talk to the cloud and get running. When doing a chat with Enphase, they said it doesn't talk on the power line communication like the other Enphase micros.

Does anyone have any experience with these? Anyone have any IQ8 battery systems? Opened one up and looked how it's built? Is it modular? Is it that I have an IQ7 system and the IQ8-BAT needs a System controller 2 or 3 to talk to? Even though the IQ8s are supposed to play nice on an IQ7 based system with the new Envoy/Gateway firmware.

As you can guess, I wanted to test this out with a wind turbine.

Thanks.

Pat
