I found much more on how to run it with solar.
There is also already an existing big installation base in Bavaria (Germany) without any big issues.
Are you referencing the short band interference of inverted?
Do you have a source which would describe the issue and the real impact globally?
Big installations are actually well engineered. It’s the residential solar projects that cause the most issues with their microinverters. SolarEdge is a huge culprit.
The impact is being unable to use HF communications during daylight hours within 500m of a residential solar installation that does not follow good engineering practices.
In the US, there is literally a single person at the FCC who handles such complaints. It is the same in every country. Anyway, what would the local RF association do? Send a letter?
There is an IEEE working group to establish residential solar installation “good engineering practices”, but we are years off from seeing anything, and even then it’s just a recommendation.
> Bremen Airport reported a fault signal in the communication between tower and cockpit. After an elaborate investigation, our measurement technicians found a marten repeller in the attic of a family home near the airport.
That sounds like EMI to me, but a different example they gave was that the wireless keyfob of the complainant's car didn't work on one side of the house (but worked on the other side), with the culprit being a small weather station at a neighbor that ran on the wrong frequency "due to a defect".
I'm not sure to what extend the offending devices affect safety critical infrastructure, but if they are sufficiently broadband, I'd expect them to hit such a frequency allocation. In that case, the BNetzA can and afaik will order the offender to turn off and fix before turning back on.
Also note the german amateur radio club's information on the subject: https://www.darc.de/der-club/referate/emv/emv-abhilfemassnah... "EMC (the EMI-sense) mitigation measures".
