You might try calling Enphase again. I was discussing a similar issue with<br>
them recently and they said that they have a noise filter option for<br>
handling noisy lines. As with all tech support, some representatives are<br>
better than others.<br>

Subject: [RE-wrenches] Power line communications interference<br>
<br>
Friends:<br>
<br>
In the old days of the Sunny Boy Control Light we battled problems with<br>
power line communications due to interference from external sources.  I am<br>
now troubleshooting a problem with and Enphase Envoy.  I have spoken to<br>
Tech Support several ties about this.  I was told I need to move the Envoy<br>
out to the array, not an elegant solution.<br>
<br>
Never once was it suggested that interference could be the problem but it<br>
turns out when we turn off a pond pump the system communicates flawlessly.<br>
Have any of you dealt with this?  If so, what have you done to remedy the<br>
problem?<br>
