Try factory defaults reset using pin 9999, then try turn on low noise mode.

Hi Tertius, I'm getting the following error in the log after starting the addon. I've cut out the voltage info of my two AM-2 packs from the log to shorten it. After I get the error below, the addon halts, and I have to start it again. " Hello BMS Pace Starting up ... -all the voltage info of the two packs- ... Pack 2, SOH: 100.0 % Script running....

Not near the inverter now, but this option was available on this inverter on versions 3382 and 3384. (5kW model) Only tried it on 3384 though. The photo above is from an inverter on 3384.

Here you go

We were having this issue with an installation of a brand new January 2023 manufactured 5kW unit. 15kHz noise from various devices around the premises, primarily from the EMI filter board on the microwave. Also from the breakers in the main DB. This is all the time, no matter if there's grid power or not. I had Sunsynk support upgrade the firmware from 3382 to 3384, which did not fix the issue. A new setting is now available under the battery settings on the inverter, called "Low Noise Mode". By turning this on the inverter restarted and the noise was immediately gone. Previously we were able to clearly hear and measure the noise at 15kHz using a spectrum analyser app like others have done. Now there is absolutely nothing. I assume that it's now switching at 20kHz as some have suggested, but I can't hear this if it is though. I still consider my hearing pretty decent on high frequencies, but I'm sure it's not as good as a young child. Either way we're very happy with the result. Note, we did ask Sunsynk support on WhatsApp what the new "Low Noise Mode" setting did before turning it on, and they didn't know. They said it was new, and would ask their technical team. I had a hunch this was the fabled inverter EMI noise reduction setting, and just gave it a go.

Hi there, A few days ago I was trying to diagnose some nuisance tripping of an ELU/RCB and it got me considering the use of individual RCBO's, even given their usual premium price. I know that in the UK the use of RCBO's is commonplace now, on basically all circuits in a DB. It seems a smart move, considering how here in SA we usually only see one ELU in a DB, for a whole bank of breakers. Then yesterday I happened across these Swan "ADL9-32" RCBO's. I have seen Swan breakers before, but haven't used them, nor had I seen these particular units. I figure/figured the quality would be similar to the other, shall we say, off-brand breaker brands (like ACDC, etc.), but I also fully expected their price to be astronomical and/or they to simply be a rarity out of the catalogue. Well, I see they range in price from about R160 to R220 for the 10, 16, 20 and 32A versions it comes in, and Mantech has them in stock. It seems Swan and Mantech are from the same holding company, hence them stocking them. But that price seems almost too good to be true. They use 1 din space, so I'm thinking they probably only break one conductor, not both? Not sure how else they would fit the ELU portion and the Overload portion into such a tiny space, and even have them rated at 4.5kA. Anyone have any experience with these things? Or any other Swan brand breakers? I've attached the stock catalogue photo of the C20.
