<div class="moz-cite-prefix">Funny the timing of the Wrenches list,
just Saturday I added some Enphase inverters to an existing GTB
Outback system. The Enphase are not AC coupled to the Outbacks,
as I didn't want to get into the battery charging issues, and the
customer has plenty of PV relative to the battery size. However,
we're having a communication issue as well. I'm guessing that the
Envoy can't be on the Outback side of the system with the Enphase
inverters being on the grid side. So, is there an elegant
solution besides putting the Envoy on the grid side of the system
(which is out in the garage) The whole house is on back up, so no
grid direct circuits are available there, and the wiring is such
that it would not be easy to change that either.<br>
I was actually going to add a transfer switch to the Enphase
circuit, so that in an extended outage, the customer could have
the option of bringing in the Enphase inverters. I have the
Enphase breaker in the Outback Flex 500 box already, so at least
that would be simple.<br>

You can remove the microinverters from an Envoy, but it requires
a laptop and a network cable. Call me and we can talk. We have
a lot of big projects with home builders, and I am more than
happy to share our best practices with you. My cell number is

I'm being told that "we" (as opposed to "Enhpase")
cannot delete or remove rogue inverters from the Array
Builder. Enphase has to do this step. And if you just
don't include the rogue inverters in the Array Builder
you are building for a particular system, you will still
receive the production data from the rogues. (2nd hand

Since some of these are home builder's 'show homes' and

has not always been set up yet, so in some of these

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>
