This is factory removable display firmware version 02.83 for the Axpert King 1 (not II) and Axpert VM III (older versions, NOT 4 kW or 6 kW or Twin). It has support for several BMS battery types, including LIB and LIC. The mcu.hex file is dated 2022-10-06, but as of April 2024, it is the latest such firmware I know of. This display firmware is "universal" in the sense that it can run unmodified on both STI (original) and GigaDevice (newer) ARM MCU chipsets. In other words, this can replace older display firmware such as 102.73, or any display firmware with the major version numbers 102 or 02.

Do not use with any other model. Works with either 24 V or 48 V inverters in the above models. Cannot be updated by USB stick; RS-232 and Windows PC (or emulator) required. Use at your own risk.

Firmware update instructions (covers DSP and MCU updating).
