The version is the same as when I purchased it. There has not been any change. The update instruction leads into error as I wrote here "Home > Renewable Energy > Inverters > AXPERT MAX II 8kw firmware > AXPERT MAX II 8kw firmware" On the USB-stick I renamed MAXII8K 281.05 patched.inv -> mks2.hex . The only file on stick. After UPG - YES - the diyplay shows U03 in red letters and the blue ring changed to red What have I done wrong?

Hi Coulomb, after my post "Axpert Max II, 10kW" I just tried the "dsp 281.05 Axpert Max II 8kW patched firmware.zip 281.05" on my device "MAX II 8kW and 28066 processor, round display" with 281.02 firmware On the USB-stick I renamed MAXII8K 281.05 patched.inv -> mks2.hex After UPG - YES - the diyplay shows U03 in red letters and the ring changed to red

Hello, I am a silent reader and love your work! Actually I 'm on the way to use this patch as 90V solution: dsp 281.05 Axpert Max II 8kW patched firmware.zip 281.05 My inverter shows 281.02 firmware.
