What firmware versions are working for it? I need to know that to select the right '2809 or '28066 firmware.

So '28066 then.

Alas, I forgot that Axpert Max II 11kW firmwares are extremely rare. I only have one, and it's for '2809 and a Twin model.

Sorry!

As a point of interest, if you recall, what was the original firmware version it came with?

Inverter arrived with error 32, I still have the original board with the label on the DSP. is 3927-03G

Also , i can use firmware for MAX 11Kw but need to change power buton with other ON/OFF. Original is PUSH button
