Hi Phut, please tell me what software version you have and what COM port you have on the inverter, because you have a voltage of - 12 V on the RS232 port for the wifi module, so I also burned an rs232 - usb converter.

I have two models with the same parameters, but the blue one does exactly the same as my colleague's, it disconnects mppt, I took the control board from the white one and put one on the blue one and it works normally, I think the software is to blame, I mention that the softwares are different

But they have a single mppt of 27A, I don't know if it will have the necessary power to produce at least 8 Kw.

Yes, exactly as I experienced with them, they say that the inverter is 10.2kw, but it is 7.2 - 8.2kw, only colleagues who have the same motherboard, the model is 156-050113-00G(B) can tell which inverters is still used

Aceasta este placa de control și folosește TMS320F28062PZT

Hello, you can't see anything from the video, but I can tell you that the inverters don't have 10.2 kw, I think they are 7.2-8.2 kw,
