Final Update. After the unsuccessful attempt to mitigate the RFI with the Sunsynk supplied ferrite ring, and the purchased In Line filters, I advised Ofcom of the situation. Their engineer advised that they were working with this manufacturer on another case, and that they had supplied and...

Hi John You are correct, the CE and UKCA marking should indicate that the manufacturer has complied with the required testing to the generic and/or harmonized EMC standards, but when neither of these standards require testing of the DC Battery Port, the manufacturer can still claim compliance...

Hi Since installing the Inline AC and DC filters we found that these only slightly reduced the RFI. The majority of the RFI on these inverters is actually coming from the Battery DC Cable. Sunsynk have been aware of this for a while as they introduced ferrites to be installed on the Battery DC...

It happens a lot when they brew their own antennas (especially wire ones in built up areas) and use more power than is required. On that note, Ofcom just raised the Full license limit to 1kW (up from 400w), so I would expect that there will be a lot more complaints about RFI flooding the help...

Hi John This I know all about, unfortunately this fundamental requirement is apparently ignored by everyone even the regulator when it comes to Solar. Ofcom don't feel it falls under their remit currently unless it causes harm to essential services like military, aviation, emergency services...

Tell me about it John.

Think your correct, I notice that when i rotate my antenna away from the source direction it drops the signal quite a lot, and is not visible on the scope , however the carrier tone is still detectable. I'm actually quite disappointed that the RFI has not been reduced more considering that every...

EMI Filters that were Installed are as follows..... 2 x Schaffner FN2200-25-33 1.2Kv DC 25 Amp High Performance Inline EMI Filter on each Solar Panel String 1 x Schaffner FN2410-32-33 250VAC 32 Amp High Performance Inline EMI Filter on AC LIne to consumer Unit 2 off FN2200-25-33 on Solar Panel...

Well, out of the blue this morning I got a call from the Installers who called to say they had just installed the supplied ferrite rings from Sunsynk and could I check the radio for interference. There was an immediate improvement in the RFI but still a reasonable amount was present. I handed...

Well I could debate all day if they actually did anything....I don't think their position has changed at all and they were just passing on the message. Was still nice to be remembered ....I did'nt expect to hear anything from them again. They also want me to let them how the mitigation works out...

Well a quick update. I have all the EMI filters and Ferrite Beads at hand now, but a few more things have transpired over the past few weeks. The regulator called and informed me that they now have a 3rd case with the same inverter model, but this time it has been installed by another amateur...

I guess it depend if the CT coil is using a DC current, hence the stated max of 10m on cable extension. I looked at installing a similar set up where I thought about putting a hybrid system in my garage as opposed to an AC coupled battery. It was some time ago, and I cant remember where I saw...

Just a quick update. The Installer has replied stating that there were no Ferrite Cores supplied in the kit of parts with the inverter. They even opened a new inverter from stock and found no cores. I have asked them to get in touch with Sunsynk and enquire why they are in the manual but not...

Thanks for your reply. The photo is not of the installation concerning my case. It is of another case whom I am currently working with in tandem to mine to find a resolution. If you look at the Orange DC Battery Cables you will see they are clearly within the circle. As the PV Input cables are...

So a quick update. Schaffner responded with ...."not enough info to make a conclusive determination on products to use" "pick some filters and try them" (my words) kind of reply. Really quite disappointing but it is what it is. I was contacted by another radio guy who has the same RFI problem...

Some very interesting reading here. This is a translated PDF from the Dutch Regulator RDI from May 2023 which was referenced in the article HERE concerning compliance of Solar Installations to EU standards. Enjoy

The Feb 2024 issue has also been sent to me, which further discusses this increasing EMC issue with Solar systems. Apologies again for the image quality, however most of it is readable. I have also attached a photo of my radios spectrum scope showing the RFI I am receiving.....my scope looks...

A quick update on progress, and some interesting reading (see attachments) regarding this issue from RSGB Oct 2023 EMC Matters by Dr David Lauder if anyone is interested. I am still waiting for a response from Schaffner's application Engineer regarding the correct filters to use, however this...

Hi John. I looked into this and its a dead end unfortunately, and I am not at that stage yet (Hopefully wont be either!) The only possibility of a legal route is to hire a specialist solicitor and purse Nuisance Legislation. There would be no guarantee of a successful outcome, as impact would be...
