Mac,

I was referring to the PLC between micros and gateway, not gateway and local router.

I don't think we have published a max distance in any of our recent tech briefs or planning guides.  That said, in some of our commercial design guides we had previously recommended up to 250 ft in a non-filtered environment and up to 600 ft when the IQ Gateway and microinverters are located on the load side of a power line filter or an isolation transformer (for example, on a dedicated 480V primary to 120/208V secondary transformer).
