<p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Hi wrenches:<br>
One thing to keep in mind is that a 15 inverter string
contains 78' of #14 just on the inverters output cables. Depending on the
homerun length, it can be further. Additionally, you will have the AC run
back to the distribution panel, and then the additional residential wiring (#12
or #14) to the jack nearest to the router. This can easily become 200' to
300' of wiring between the last inverter and the Envoy. However, steps
can be taken to minimize the issues, and I have always found a resolution to my
communication issues.<br>
Breaking the string into two 7-8 module parallel strings
(and then paralleling them at a j-box) can reduce the distance and voltage drop
from the Enphase inverter output cables. <br>
I have installed many systems that have had communication
issues between the Envoy and the inverters. In the past, I have installed
new receptacles or run CAT 5 from the Envoy to the router. That is time
consuming, and there is a much easier way to deal with it. I have resolved most
of my communication issues by installing the 'Ethernet Bridge' which is a 2nd
power line carrier modem and its receiver. This product enables the Envoy
to be located away from the router (and closer to the array.) The
'Ethernet Bridge' is a product offered by Enphase.<o:p></o:p></span></p>

I was told 300 feet by an Enphase Rep. We have a system that is at <br>
least that far from the Envoy.<br>
