[RE-wrenches] Comms for mixed IQ-series and legacy Enphase circuit

[Nathan J. Stumpff]

Jason and Nick,

Thanks much, this is great. I am managing the project remotely but now I
know the right questions to ask. FWIW, we did not get the same, simple
answer from Enphase tech support.

Thanks,
-Nathan
