[RE-wrenches] Enphase Max Distance

[Nick Soleil]

HI Rick,

The distance that our power line communications (PLC) signals travel will be impacted by the electrical noise on the site and the impedance of the wiring.  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).

Keep in mind that when the PLC signals are used for controlling the microinverters, such as sites that have power export limiting (PEL) profiles or when the microinverters are paired with IQ Storage systems, the communications must be more reliable than when used for monitoring alone.


Cordially,

Nick Soleil

Wrenches,

What is the furthest that anyone has placed their IQ-based system from the gateway? Enphase recommends up to 250’. We’ve done ~350’ without issue. Anyone gone further?

Thanks in advance.
