hello, I'm sorry to bother you, to this inverter and I connected to it a 3.5kw wind turbine from the windspot, so I don't use it with photovoltaic panels, I use it with the wind turbine, in order to have efficiency at the wind turbine, I have to enter the load  mppt at 230v to 270v maximum it from the factory is from 120v to 439v, you can change this value that I have circled in red, thank you in advance

I don't think it's practical to attempt this. Solar MPPTs are quite different to wind MPPTs.

I don't know much about wind turbine controllers, but I think you'll need a special charge controller designed for wind input.

I've been using it for a year and it's working, the only problem is that when you turn it down to 120v mppt and the wind turbine goes under the speed, if you could change the firmware from 220v to 270 that would be ideal

Ah. I've just noticed that it's an InfiniSolar, not any kind of Axpert. I am usually not confident at all with the Infini firmware, but the Infini V series seem very "Axpert like". I've just had a look and I do have an Axpert Infini V firmware. If your current U1 firmware is 56.xx, then it's actually easy to change the minimum and maximum MPPT voltages.

So please tell me your present U1 firmware version.

Dang. I don't have a 52.xx to work from. My guess is that it's the "other DSP" version of the 56.xx firmware. 56.xx is for the '28066 processor.

Edit: If you can find a firmware update file for your model (52.xx), I'd have a go at patching it. I would be intrigued to know the result.

ok I'm looking for the latest firmware from my model it would be perfect if you manage to modify it I'll be on the lookout for a donation 😁 with the greatest pleasure

I've had surprisingly big problems having people donate to me. I've just set up Buy Me A Coffee, that should be easier for everyone:

Thanks in advance to anyone else that wants to support my work.

Descrierea pare să fie greșită, am cumpărat un Easun și în descrierea ebay a fost ca captura de ecran, dar în imaginile de acolo s-a explicat că cei 120A sunt combinați.

 

Sau poate ai avut într-adevăr hardware mai bun în invertorul tău?

 

Ai primit încărcare solară de 120 A cu firmware-ul original?

I knew that in the past, i could charge from solar with 120A

Dang. Non ho un 52. xx da cui lavorare. La mia ipotesi è che sia l'altra versione DSP del firmware 56. xx. 56. xx è per il processore '28066.

Modifica: Se riesci a trovare un file di aggiornamento del firmware per il tuo modello (52. xx), avrei un'idea di patcharlo. sarei incuriosito nel conoscere il risultato.

I searched and I can't find a firmware for my inverters, neither original nor upgrade, basically this type of inverter is the same as those from MPPSOLAR, EASUNPOWER, ETC, how do I find a compatible firmware so you can modify it

Usually you wait and wait and check and check.

Amazingly, one was released a few weeks ago, and I've just patched it. You asked for 230-260 V in one post and 220-270 V in another, I went with the wider range (220 - 270 V).

This is patched firmware version 252.31 for Infini V II 5kW '2809. It only fixes the premature float bug, and changes the MPPT minimum and maximum voltages to 220 V and 270 V respectively, as requested by @bubu_bubu. Few other readers would be able to make use of this patched firmware.

This firmware should show as version 52.31 on the display, but as 252.31 on monitoring software, or in the first response of the secure P_VFW command (roughly equivalent to the Axpert QVFW command).

I don't know the Infinis well, but it seems that the Infini Vs are very similar to Axperts, at least in firmware layout.

The "stuck at 90V" changes are not applied; it seems to me that they should not be needed in this application, considering the narrow "PV" voltage range.

As usual, the original firmware is included in the archive, so with a little renaming of files, you can upload factory firmware version 52.31. As always, it's not possible to revert to exactly whatever was loaded at the factory (52.20 in this case). 52.35's dsp.hex is dated 7/Jan/2023.

Use at your own risk.

Great, tomorrow I'll try it and I'll tell you exactly how it goes, I hope the wind blows outside so I'll do the test too, you can send me an email if there's anything I can ask you, If I don't leave you mine, bubu.liviu @yahoo.it, or whatsapp +40763785869

Hi Coulomb, i have your firmware 92.05 with 200v, with arenaflash, on easun 8k, its working ok buy, in much times in a day, i can see the inverter that goes in 200v, for 5/10 seconds, after that its going again in the max v. The sun is there when makes this. In that times im.loosing power, i have 450v input now on each mppt, its not too less that 200 voltage for me? Which is the best voltage ? Thanks

Sorry, you guys will have to tell me, not the other way around. I don't own a Max, I just happen to have a knack for patching firmware.

I wouldn't be doing this at all if it wasn't for @Georg594 showing the way. He owns a Max, so he can figure out what works and what doesn't. I can copy his patches into other firmware versions, or occasionally suggest something like my "reset the MPPT every 5 minutes" idea.

Hopefully, with many owners contributing data and observations, we'll eventually converge on the best way to fix these MPPT problems, then it will be a matter of cranking out patches for all the various models out there, and many of their variants with respect to chipsets, dual outputs, dual inputs, etc.

Îmi pare rău, băieți, va trebui să-mi spuneți, nu invers. Nu dețin un Max, pur și simplu am un talent pentru corecțiile firmware-ului.

Nu aș face asta deloc dacă n-ar fi fost@Georg594 arătând calea. El deține un Max, așa că își poate da seama ce funcționează și ce nu. Îi pot copia patch-urile în alte versiuni de firmware sau pot sugera ocazional ceva de genul ideii mele „resetează MPPT la fiecare 5 minute”.

Sperăm că, cu mulți proprietari care contribuie cu date și observații, vom ajunge în cele din urmă la cel mai bun mod de a remedia aceste probleme MPPT, apoi va fi o chestiune de a crea patch-uri pentru toate modelele diferite și pentru multe dintre variantele lor cu respect. la chipset-uri, ieșiri duale, intrări duale etc.

@Georg594can u help us? Which is the best voltage ? @Coulomb my mppt voltage didnt decrease under 350v in full load never. It woult be better to increase it to 300v for example in the firmware? The other inverters what vojtage have there in the firmwares ?

With help supply connected it seems to be the better the higher ....175V was the best compromise for me when help supply was connected .

 

In normal operating you Gain nothing with a higher mppt min voltage, this is just a easier step for the help supply to Start.

 

Without help supply we could go below the original 90v without any power loss.

Cu sursa de ajutor conectată, se pare că este cu atât mai bună, cu atât mai mare... 175V a fost cel mai bun compromis pentru mine când sursa de ajutor a fost conectată.

 

În funcționare normală, nu obțineți nimic cu o tensiune min. mppt mai mare, acesta este doar un pas mai ușor pentru ca alimentarea de ajutor să pornească.

 

Fără ajutor de alimentare, am putea coborî sub valoarea originală de 90 V fără nicio pierdere de putere.

I have the help source connected now, and 200v firmware, voc on mppt have 450v, never step down under.300v, but i saw that goes in 200v much times.on.a.day.even the sun is up, do u think i would try 300v ? @Coulombcan help me with the firmware 92.05 arena flash modified with 300v and one with 350v? I want to test. Thanks

Ok. When u will have time, pls modify for me the 92.05 arena firmware with 300v and 1 with 350v, i want to test. Thanks

 

 

 

Bit of a weird thing I've realised. When one of my strings becomes shaded they both drop off before one recovers but jumps up and down on volts and Amps 

The first photo is what is what I would expect and the the other two are the issue I'm referring toScreenshot_20230219_160040_Chrome.thumb.jpg.41b50d1ea31b2dc44e58381afe81d5e9.jpgScreenshot_20230219_155732_Chrome.thumb.jpg.5d41858872051c127c1f012158041484.jpgScreenshot_20230219_155538_Chrome.thumb.jpg.08b8841373d89297faec1d470d513046.jpg

Hi all,

 

Need to have your advices before to brick something.

I got an axpert max 1 8K (from solarpower24) bought in 2021. I am still with the original formware

U1 : 46.04

U2: 12.05

U3: 88?88

Got two strings attached to it :

PV1 : 6 x 335Wc (Voc 40.50V)  (south/south east)

and PV2 : 10 x 335Wc (south west)

What would be the best firmware I could use for it ? (to maximize of course low light performances)

Thanks in advance
