Hi Geoff RFI Is constant 24/7. Yes has a Sunsynk 5Kw battery. Even when there was a power cut there was RFI so the inverter is clearly very poorly suppressed or perhaps has no suppression at all ! The RFI is being generated by the high speed switching process in the inverter and being conducted...

Hi. Your comments are so true. I often feel that everything is a David and Goliath challenge these days? In these past four years I have been confronted with so many issues you would'nt believe. Boundary disputes, seeking court interdicts, property rights disrespected, solicitors ignored...

Hi Bill I wish I could just build a homebrew filter for this, would work out much cheaper, but as its a new build and was commissioned by the owner to a property developer who then sub contracted the Solar and electrical works, the install has to comply with RoSH, MSC and all the other standards...

Hi Fella, thanks for your comments. I completely agree with everything you have said. The situation with non compliant devices flooding the Western World from China is out of hand now. On You tube there are videos of people opening laptop PSUs and finding blocks of cement or epoxy resin to give...

Thanks Stevie for the information. I was thinking about cables and screening today, although the runs from the inverter to the EMC filters would be very short. I was considering the implications of having unscreened cables and if this would produce detectable amounts of RFI. I also noticed that...

Hi there...Thanks for making a post. I dont have access to that article in ARRL unfortunately, but I will have a look for it and see if I can find it outwith ARRL. I was looking for David Lauders article in Oct 2023 Radcom also, but RSGB have website issues and Im having difficulty getting that...

Hello John. Should be Ofcom, but they dont seem to be very efficient in doing their job. I really dont think they have the resources to pursue costly investigations, and continuously seem to be draggged in front of the Ombudsman.

Hi thanks for commenting. Yes I have been in regular contact with RSGB EMC Helpdesk and also Dr D Lauder the Author of Radcom EMC Matters (RSGB magazine). As helpful as they have been there is little they can do, as the society does not have any enforcement powers unfortunately. Cheers

Hi Dave thanks for commenting. I think it is being generally noted that the majority of EU manufactured Inverters comply with the EU legislation and produce very little RFI as all products should to meet the requirements of the Essential Requirements. The problems seems to be the cheap stuff...

Nail on head....this is my conclusion also. I have however heard of a radio guy who got an inverter installed and found it to be noisy as hell. He sent the device to a testing lab, found it failed and went back to the manufacturer who changed the design. It cost him loads to do but now the...

Hi Thanks for the reply. I emailed Sunsynk in early December and got a reply from their Technical Support last week stating to "Enable Low Noise Mode" in the battery settings page.....Needless to say this made no difference at all to the RFI. I wish I could actually speak to someone who had...

Hi Thanks for the reply. You make a good point. I tried to call Shaffner yesterday but got hung up on twice. I will try again though. Its increasing difficult to find any help for this issue, as it seems to be outwith most peoples experience and/or scope of knowledge unless within radio...

Hi Many thanks for your comments. It is something I had not thought about, however I dont know how practical making these modifications would be now as the house has just been completed and signed over to the new owners. I am not surprised that there is little awareness of this issue, as very...

Hi I am hoping this is the right place to seek some knowledgeable advice. I am an amateur radio operator and have recently had a new build property developed next door to mine in a very rural setting. Unfortunately the developers have installed a very noisy Sunsynk ECCO Hybrid 3.6Kw inverter...
