February 2, 20233 yr Hi all, I have two Pylontech US2000 running software version 2.3 and went a little wet some weeks ago. Now it works fine (charge/discharge) but doesn'comunicate SOC to the inverter so I can use batteries but can't see state of charge through the app connected to the inverter. Led indicator upon the batteries works fine. If I connect with Battery View could see batteries parameters except So I get "null Anyone have had similar issues?
February 11, 20233 yr Use the console port of the master battery and connect using the united option checked and the number of units you have. Another window named "Power information window" will open above the "Cell information window" and you will see the SOC of both modules in the table. The null value that you are seeing is either a bug in the BatteryView software or a mis configuration in the regex in one of the xml config files. Edited February 11, 20233 yr by PurePower

Thanks for your suggestion, i've used another SW, MultisibControl, and i'm able to see SOC for both batteries, see the image in attachment. In batteryView instead I can't get SOC information even if I set the comunication like you suggested. So now the question is if the batteries are fine and the problem is on the inverter side, what do you think? Now batteries works well till i connect inverter to the internet, when i do so, the inverter put the batteries in off mode....very strange issue..
February 11, 20233 yr The inverter firmware might also have to be updated or it may expect the batteries to have a certain firmware version as well. You will have to check with the manufacturer of your inverter to determine this.
