I think u asked by wrong reply. quote; ask claubeb

Thank you!

@sharkut Hi You have 11KW version Axpert Max, removable display? I have this inverter; i intent to flash 12.21 ( mine 112.19) ; i saw problems of aamilev, but he have 7.5 kw version; Thx in advance

@aamilev Hi, can you pls submit a link to Tommatech site for this one? Tommatech site info is referring to what inverter type, MPlus 11KW? Many Thx!

You should read carefully what i written few posts ago; flashing a firmware is not a joke; pay attention that such inverter have 2 firmwares: one for communication& parameters ( remote display) and one for own management.

Not marketing; I is with old chipset, II is with new chipset; and twin is different of this 2.

MAX E 11K - i don't know about it; check the posts of Coulomb; it exists more versions: MAX 1 11KW, MAX II 11 KW with color round display; also MAx 11kw Twin; the 57.61 is for MAX 1 with removable display, squared one.; pay attentions to chipset versions, otherwise you risk to brick inverter; check more times the chipset version, appropriate firmware, flashing tool, procedure, cable, etc; before flash and validate with more data sources

see above plus below; the one in box should be ok, normally; check colors if they fit with schema and insert a resistor on white wire; regarding flashing tool; pay attention where to click, update DSP or MCU ;

indeed, is required a flashing tool, windows exe; but you can open a VM on Mac:)

Is not noisy; after 57.61 is more efficient in cloudy day; I can't say 90 V is solved entirely, but is diminished.

you should flash using RJ45 cable and Usb to serial adapter with 1 Kohm resistor mounted on it; instructions on forum; USB stick flashing not work;

I had factory version 57.04, inverter purchased one year ago; so i believe 57.05 is proximal to it, quite old; Updated from January, this year to 57.61
