  2. Firmware Update Request for Axpert VM III-4000 TWIN (U1 & U2)

    yassen posted a topic in Inverters
    Hello, I have an Axpert VM III-4000 TWIN inverter and I would like to update both U1 and U2 firmware versions. I am experiencing a problem where the screen suddenly glitches: all icons and the battery indicator disappear for a few moments, accompanied by a warning buzzer and a red alarm light. This issue happens several times daily. The current version is: U1: 60.10 U2: 57.17 Please help me solve this problem. Thank you.
