Thank you, it worked!

Did you also use the U.S. measurement system

Hi @AlexTZA that was a great surgestion, but unfortunately I still get the same error.

Hello I have a pylontech US5000 battery The battery alarm licht is on, so i put it on my PC with the latest batteryview 3.0.33 But i get an error: EOF in header Just to make sure it is not a PC issue i have tried 3.0.28, 3.0.29 Then i updated the firmware trough the upgrade tool (PYLONTECH TOOLS 2.0.0) That went smooth like a breeze and the battery has now firmware version 1.7 But the alarm licht is still on and i can't get the logs or see the error messages EDIT: When it take the cover of and use a multimeter on it the battery is at 49,5V. but when i use it on the outside terminals there is no voltage. I hope someone can help me
