Sorry UUUPS Pylontech US3000C, Thanks you Christoph

I can not get the battery communicate saw a instruction pdf online from .. solar supplies, they say connect the yellow cable on the can port on the battery and BMS/CAN on the inverter and only dip switch 1 in on position everything else OFF. I have done that but it does not work, even reset the inverter to factory settings I tried a different R45 cable same result, even measured RJ45cables with tester, both cables are standard RJ45. Can anyone tell me if the yellow cable suppled does work or where I am going wrong please. Thank You Christoph SUNSYNK-PYLONTECH-WRITE-UP-12 battery connection setup 16032023.docx

Thank You Wofandy, I will try

Hi Padwan, I am struggling with the dip switch settings for the Pylontech US3000 setup. I love your photos of the 2 US3000, but I can not 100% make out the dip switch settings I also have a Mecer Axpert MKS II 5KW high DC input up to 450DC and 80A charger and up to 4500W insolar panels. I have problems getting the full solar production and been told that my PV angle is wrong. My 3 strings of 5 X Canadian Solar 330w panels each only give me around 3-4 KW/h per day and they are installed flat on my carport I stay in Kempton Park Johannesburg and I was told to list the panel angle to 36 degrees. I am hesitant as a lot of people I know have had their panels stolen. So I invested in some SW but now it does not want to read from the inverter or the batteries and I was told that my dip switch settings on the US3000 are incorrect.According to the Pylontech manual, the way I understand it the first battery 0 should have dip switch 1 up or on and all others off or down and battery 1 or second battery dip 2 up or on and all others down or off. If I see your photo correctly you have battery 0 Ca dip 2 is up and all others down and battery 1 or second battery all 4 dips are off or down? Can anyone give me advise please
