OT - Radio interference from Solar Panels

[Bob McGraw - K4TAX]

The Swedish Electrical Safety Agency and the Swedish Energy Agency are investigating radio interference from installations with solar panels

Sweden's national amateur radio society SSA reports:  Solar panels are becoming more and more common.   An increasing problem is that interference can be created to radio reception.   The newsletter (LÄNK) from the Swedish Electricity Safety Agency states that they are looking more closely at the inverters and optimizers found in solar panel installations.  The Swedish Electric Safety Authority is doing this together with the Swedish Energy Agency in a project that is ongoing until March 2020.

Bob,
     It isn't just a problem in Sweden. We have seriously here in the
U.S. Panels put in my Solar City annd a another company, I can't
remember the name, are also rather problematic. They make no effort to
suppress the noise caused by both the equalizers nor the power
converters. There are typically no use of ferrite's, conduits, or
twisted wire. There was an article on this in QST a while back, and
several local hams have complained to the installation companies and
have had them respond and make repairs. I do believe that ham radio as a
service under the FCC is protected from these sorts of things.

It all depends on make and model. I have had two inverters of different make with no problems. I may also depend on cabling.

With my first inverter I tried running a twisted pair RS-232 line to my computer. I never got any signals to the computer BUT a lot of noise into my radio. Just unplugged the line at the inverter and all noise disappeared.
