Many thanks, the Cable I received in my 5KV Kodak King 3 weeks ago is the same as this, what made it all work was using this cable and on the Pylontech Battery Dip1 up (1) and inserting the RJ45 into RS485 socket on the battery... Now the battery icon flashes and its all happy using PyL on inverter setting 05. Still currently discharging to check battery shutdown..
