Also had this when I initially commissioned mine. With the cover plate on it was less annoying. At some point I had switched off the inverter completely and disconnected the batteries. When I turned on everything again, the pitch was really bad. After a few days I decided to just switch it off with the power button underneath the inverter - did not switch off anything. When I switched it back on, the pitch was virtually gone (it is there but really really faint only audible when I get your ears in really close). Not a technical solution but just what I experienced.

Does the graph only represent the use of your geyser and no other circuits? At what point are you measuring the use? What did you use to measure this and get this information? Agree that the rand values do not look right

Can you mix for example JA Solar with a Canadian Solar? probably not Also can't mix a poly with a mono? Found a 405watt canadian solar

Thanks Tariq and Vassen for the feedback It makes sense that BMS would limit the current draw and inform the inverter of this Saw in another thread something about the Pylon warranty that will be void if charge currents are overstepped and it got me wondering how you could manage this within the Sunsynk settings. To summarise then: 1) even if you only have two batteries, and 2) you are powering essential and non-essential loads at night, 3) the BMS will tell the inverter of the max capability/draw, 4) the inverter balance the rest of the requirement against

Hi Guys Looking through these pics again and the manual, I just need to clarify the approach on: 1) Number of batteries; 2) Max consistent current draw 3) Setting on Sunsynk system screen I know the max sell power should be set to your PV array size power however I see in most pics that the POWER COLUMN remains at either 5000 or 8000 depending on whether the person has 5.5kw or 8.8kw model. Has anyone limited the power in the power column to say 3500 watt? For example if you have two Pylon 3000C batteries with max consistent current draw of 74A

Strange that you could not find a 405 watt. Have you checked with the major distributors?

There is a training manual that could maybe shed some further light. Not sure what you are struggling with specifically

Just a wild guess here from what i have read it sounds like a floating neutral. Have you tested the voltage between earth and neutral?

Look at the training manual

Which meter is? (type) Can't you set it to minimise the export power?

Nice Now you just need a battery cabinet for those pylon's. Is that small DB for your solar protection breakers/surge arrestors/fuses?

1. Mine is wired to get power from Mains before RCD and from a "clean neutral". 2. Most guys just use a single NO/NC relay (240v coil). The coil will be connected to the live and neutral outputs of ATS240 pins on the inverter. Once you open the inverter you will clearly see these markings. The neutral (from the inverter output) or earth can be linked to the COM pole (common) and the remaining wire (neutral or earth - depends on which was connected to COM) can be connected on the NO pole. Nothing should be connected on the NC pole.

Hi Guys Many different topics discussed on this thread and very interesting. The manual however does not state the rating of the relay required but just that the ATS pins should be connected to the relay. So why would you need a 40Amp relay if there is going to be no (or minimal) current flowing through the relay - i.e. you don't expect to have 40 amps flowing between N and E? If I understand the function of the neutral - earth bond correctly, this bond is required in order to give the RCD/EL breaker the ability to detect if there is a fault and accordingly, any such variance de

The nice about the CT clamp just after the meter (so to speak) is that you start getting stats on your entire household use from the inverter. You see the peaks and the base level of use. From my perspective it was good to see this

Some interesting discussion here It seems the writing is on the wall i will have to change my installation Did not know about the metal trunking - if you look at the gallery of the power forum store it all looks like plastic trunking and in some instances ac and dc in the same conduit? Question, does SANS 10142-1:2017 Edition 2 prescribe the minimum or is it a "good practice" guide. Who regulates the wiring code? Is it not an NRS function? I.e. NRS 097-2-1:2010 Edition 1 (Not my pictures - just copied from the website)
