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

No chance for this "It would be nice to know what changes are actually made" At least you can find what versions & for what types of chipset are designed.

release note is a pdf included in zip archive Firmwareupdate Pylontech US2000C_3000C V4_0.zip

Read above https://www.effekta.com/download/firmwareupdate-for-us2000c-3000c/

Yes, use the newest as master, having the most recent firmware, as Tinbum said. I believe that it's matters also if you have the battery connected to inverter or not. But this I think is not applicable to you, having Growatt and Pylontech combination. However, is recommended to have same firmware on all batteries for same brand, it's avoid having balancing differences. I experienced this with older firmware to a stack of four Pylontech 3000C, had the master on 1.7 and two batteries with 1.4 and one with 1.2, purchased at different moments of time. They charge full equally, but after few weeks they discharged differently. solved by flashing 1.7 to all; now on 1.8.

Now it shows SOC 100% more often, previously it stayed at 98-99%; better standby management, that's all for now

Firmwareupdate Pylontech US2000C_3000C V3_1.ziplatest update, it includes v 1.8 and 2.8 for new & older chipset; the archive is no longer on effekta's site

mine is MPP Solar 11KW max, or Axpert Max 1 11kw; 112.19 is taken from forum also from some Czech site; it is said that work for Axpert max 1 11 KW. i installed since 3 months and works very well. Previously I had 112.04, stock from factory. As previously, the new 112.19 installed it show 150 A, maximum, on display; i know that firmware of 8 Kw has a limitation to 100 A, but this one shown what the inverter have in tech description. 11kw inverter have 2 streams of 5.5 kw each; i have 7 Kw installed in PV panels, reached 6.4-6.6 Kw several times, 120 A sometimes for battery charge. I just try to see if exist a newer version. because i have Pylontech (data cable connection to inverter), and the charge is dynamic, based on optimization algorithms; the battery charging voltage rise sometimes to 52.4v-53V (once) ; i would like to see if exist a variant to limit the max charging voltage to 52.4 V in display panel (to preserve battery life), of course this will increase the amperes, but reserve exist;

Hi, did someone have a newer version than 112.19 remote panel firmware, for Axpert Max 1 11 KW - or MPP Solar 11KW? Thx in advance

Thank you, i think is not compatible, my current version is 112.19 Thanks anyway
