[RE-wrenches] Enphase and Line Noise

[SunHarvest]

I really like using 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...

  Guys,

  I am thinking of getting back into using Enphase, but I am worried about
  sites with high line noise block communication with the microinverters.

  I have run into homes with light control systems and VFD pumps.

  I am wonder what folks have experienced:

  1 - How often do you encounter this problem?
  2 - What are other causes of noise that impacted the site?
  3 - How did you address, with a line filter?
  4 - How did you handle the added cost, passed it on or eat it?

  Thanks,
