[Elecraft] Enphase mini-inverter

[Vic K2VCO]

I am looking at a solar power system that uses multiple "mini-inverters", Enphase Energy 
M215-60-2LL-S2x. They use a data-over-powerline type of system to transmit information 
to/from the inverters and a central device.

Does anyone have any experience with this kind of system re RFI? Does anyone know what 
frequencies are used by the powerline communications thingy?
