Hello, I did a test version and you can see in the video that the communication is OK AX KING II.mp4

I even have 19.16 from Voltronik. If it still doesn't work, I'll try it on Monday at work with the Battery. IF there was a problem with me too. I'll deal with Voltronic Remote Panel_Reflash_MCU(19.16).rar

Do you have a Reflesh file? Version 19.14 ? With AX KING II, the problem was mainly with measuring the voltage + current from the solar input. And also the charging current to the battery. Version 50.12 will fix all this. There is also a fix for display version 19.14. What do you enter in program 5? In the inverter menu? In order for RS485 communication to work for the pylon, it must be set to PYLON. If Pytes is on DLG, it must be on LIB. Then the inverter will communicate

RS 485 is provided by the STM32F107 processor If you have version 19.14, try playing the display. I have not tried sending commands to the inverter. I tried it on a pylon battery

Have you already sold the batteries?

Latest FW is 50.12 and Display 19.14 Pylontech wiring is Inverter 3 - 5 and battery 7 - 8

Hi. I have already solved this problem. The whole problem is that STM 32 is KO. This is the main processor on the board, which has version 35.73 loaded into it. The stabilizer marked in the picture is shorted to GND. Hence the warm place.
