Posted February 9, 20241 yr Hello Guys I hope you are well. I am trying to upgrade my Pylontech US3000A and US3000C batteries. I have the latest firmware as supplied by Segen. I have tried BatteryView v3.0.24, 28 and 33. When I try to connect to the batteries I get this error. Any hints to what is causing this? Regards, Simon
February 9, 20241 yr Hi, you need a cable for US3000A/B and a different cable for US3000C. Are you using the correct cable? Can you see all the cells when you connect, voltages etc? Make sure you have the correct firmware for A/B and C. There are various versions for type C depending on motherboard version.
February 9, 20241 yr You will require this cable RS232 to USB Converter Cable Kit for Pylontech | SegenSolar. It has both connectors for the different console ports i.e. RJ11 for US3000A and RJ45 for US3000C. I have found that Battery View will also require you to set your computers REGION setting to United States.

February 24, 20241 yr Author Ok, I will double check the settings. Yes I have two different sets of cables for the US3000A and the US3000C. I used to run the US3000A as the primary batteries (before getting the US3000C) and had the small terminator (whatever its name is). I use the different cable now to connect to the console of the US3000C. So I have both sets of cables. I will try set the regional settings to US and see what happens. Going to try it now. Thank you!
February 28, 20241 yr Author Set the region settings to the US and it still exceptioned. Hurry up and time to wait for Segen again...... tioned.
February 28, 20241 yr I suspect you might have an issue with the console cable. I had a similar situation and found that the cable was no longer working correctly. Check the windows device manager prior to plugging the cable in and then check it again after plugging it in to ensure you see both a COM port and a Universal Serial Bus controller.
March 1, 20241 yr Just for interest sake, why do you need to upgrade Pylontech batteries? Mine are a mix of 9 between 2-4 years old, are they supposed to be upgraded?

It looks like it is an error with the date formatting the software is struggling with, it might be the order of the date, try changing it to day/month/year instead. You might also need to change your number formatting to a . for decimals and a , for thousands seperator.

Yeah it is showing up as COMX and device manager registering it too.
