[Elecraft] Noise from Solar System

[Dave New, N8SBE]

John,

I have a 5.4kW array of 15 panels on the south-facing roofs of my house. 
  They use Enphase microinverters, so they put out 240VAC which is synced 
to the 60Hz signal from my electrical provider (we are on net metering), 
so there is no 'house' inverter.

You can see the output from my array here:

I have had ZERO RFI from this installation.  We have a local radio club 
member that has done extensive work with solar on his house, and had 
experimented with a couple of panels and Enphase microinverters before 
committing to a roof-full of them.  He also has another array which is 
DC, and connected to a DIY Solar inverter.  DIY Solar is owned by a ham, 
and his inverters are very quiet, also.

Hope that helps.

73,
