There have been countless articles about solar causing RFI. Mine was no exception. I have a SolarEdge system that uses optimizers. I got this before I got into amateur radio, and it definitely made using the radio during the day impossible. I've been working with TJ Simpson from SolarEdge (contact info: firstname.lastname@example.org / 510-498-3262). Tom has coordinated ordering LOTS of ferrite, in addition to new SolarEdge optimizers that use spread-spectrum technology to help with reducing the overall RFI. They are working on replacing the optimizers and adding the ferrite as I am writing this. The test will come once they are completed! I will post an update and let everyone know how it goes. For those in the central FL area, I can't say enough about SEMPower as well - they have been a fantastic company to deal with!!
