Hi Benn,<br>
<br>
We've run into these problems when simultaneously commissioning
systems in adjacent units of a housing development where we did PV
systems on all homes, and 2-3 homes are on one utility
transformer. I'm a little surprised that the Envoy picked up
inverters from an existing system, unless those microinverters
were never associated with another Envoy. My understanding from
Enphase is that once they are "bound" to one Envoy, they won't be
easily picked up in a device scan. But maybe I'm missing
something, or got bad info from tech support.<br>
<br>
We've definitely had to work with Enphase tech support on a couple
of systems to remove inverters from one Envoy, then do a device
scan on another Envoy, as August suggested. Another option is to
spend the money for the Array Gun scanner (SocketMobile CHS7xi
scanner), and use the iOS Enphase Installer Toolkit app to build
arrays and "provision" the Envoy, sending the inverter serial
numbers directly to the Envoy, without need for a device scan. Not
sure if this is worth it at the $450 retail price for the scanner,
but if you can find one used, it might be. I recently was able to
pick one up for about $250 used.<br>
<br>
Haven't yet had issues serious enough to require LCFs on
residential systems. Crossing my fingers on that one.<br>
<br>
Best,<br>

install and i plugged in the EMU to search for the inverters.
As it was picking up the first few inverters, it was showing
several hundred kWh already produced??? Not bad for a 14
module system being in operation for 10 min!!! (yes the
inverters were new, out of the box)</div>

<div class="gmail_default" style="font-family:trebuchet

inverters in total. There were 14 on the system we had just
installed, and 14 on a house across the street that we had
installed back in Nov'13. I'm pretty sure it had picked up
the 14 across the street before picking up the ones we just
installed.<br>
Funny that we can sometimes have communication issues btwn the
inverters and EMU in some houses, and here we have EMU's
picking up inverters across the street!?!</div>
