hi, the problem was the original cable which was no longer communicating with the battery. i had to build another cable using new config.

@TT5, where you able to resolve your issue. I just moved from Growatt to Deye and I am experiencing the same issue as well. I changed the CT to point the other direction and nothing happened then I changed it back. My CT is pointing to the inverter direction. Will appreciate your feedback.

Sorry Jeff for the late response. Fortunately I have not had any problems with my 500.12 for the past 8 months. My inverter fan has been working quite well.

SUB is not available on SPF5000TL. Only on ES inverters

Try upgrading first to 500.09 and also update your comms and BMS firmware . if it still does not work, check your cable connections id they are all tide.

Hi Strauss, Out of interest, I saw that your battery reaches 99%. Does it ever reach 100%? Mine never reach 100%. Always around 99%. If I run everything on battery, it does go down and when I bring back power, it charges upto 99 percentage. Will like to hear your view...

Thank you JTK, also experiencing load shedding since 18:00. I will try as suggested.👍

@JTK, your GND is on which pin on the inverter side?

Thank you for your response. 1. Still not working. Is your baud rate dip switch setup to 9600 on the battery? 2. Cable connection is Inverter- BMS -------> Battery RS485? Cables us testing fine with only 3 pins on both sides. Maybe there is something wrong with my BMS board. Thank you anyway

I tried that and maybe I amissing something. Please see my pins for both battery and inverter. I tried the layout exactly, I think so🤔 Will appreciate your assistance.

Thank you. Trying that

Do you mind sharing pictures of you cable pins please

@JTK, whats the ground line?
