  1. Firmware update for Axpert Max Twin 8K – Pylontech Fidus BMS connection

    SP4E posted a topic in Inverters
    Hi! I’m looking for the latest firmware update for my Axpert Max Twin 8K inverter. I tried connecting a Pylontech Fidus battery through the BMS communication port, but the inverter cannot establish communication with it. The battery currently works only in User-Defined mode, without BMS communication. Does anyone have a compatible firmware version or know whether this battery is supported? I would also appreciate instructions on how to safely update the firmware. Main CPU Firmware: 77.10 Secondary CPU Firmware: 38.18 Thanks in advance!
