<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I completely agree about PV dedicated power centers
& connections. I talked with the homeowner about having the Envoy located in
the detached garage several hundred feet away from the house where the
solar is mounted and tied into a dedicated sub but he insisted the
Envoy be located in the house. I'll give the Digi-Key filter a try.
Thank you!</FONT></DIV>

difficult Enphase interference problems. I was told this and did not
believe at first, but always, always, bring your Enphase feeds into a separate
sub-panel. In that sub-panel install the breaker feeding the receptacle
for the Envoy. This way you can filter the feeder to that sub-panel and
it is isolated from the entirety of the remaining electrical system.

Enphase but my most recent customer just informed me that his pool lighting
is now turning on and off intermittently after the PV install completion.
The lights are controlled via a timer on the neutral line. I'm pretty green
when it comes to controls so I don't have a solution yet. Just thought I'd add
my experience in response to your query. Look forward to what others have to
say about this...</SPAN><o:p></o:p></P></DIV>

<P class=MsoNormal>Guys,<BR><BR>I am thinking of getting back into using
Enphase, but I am worried about<BR>sites with high line noise block
communication with the microinverters.<BR><BR>I have run into homes with
light control systems and VFD pumps.<BR><BR>I am wonder what folks have
experienced:<BR><BR>1 - How often do you encounter this problem?<BR>2 - What
are other causes of noise that impacted the site?<BR>3 - How did you
address, with a line filter?<BR>4 - How did you handle the added cost,
passed it on or eat it?<BR><BR>Thanks,<BR><BR>Mark Frye<BR>Berkeley Solar
