I presume you mean can I patch 72.66 to have the same 250 V check that 64.62 has? That seems like an easy pair of patches, so I had a look to see how easy it would be. Alas, I found that this check is already present in factory firmware version 72.66, and therefore also in all patched firmwares it is based on, such as patched firmware version 272.66. I presume that you have tested patched firmware version 272.66, and it leaves something to be desired? Or perhaps it works OK, but you'd prefer a "Voltronic approved" algorithm?
August 22, 20232 yr 5 hours ago, Coulomb said: such as patched firmware version 272.66. Sigh. I went looking for a link to this patched firmware, and was surprised that I didn't find it. So I thought I'd attach it here, and was surprised to find that I could not even find the .zip file on my hard drive. When I looked closely at the .txt file, I see that I had just started on this (back in March 2023), and somehow never progressed with it! Sigh. My apologies. I'll convert it to an assembler patch which is the way I do patches these days (it should save some time). So the bad news is that Voltronic still haven't fixed the stuck at 90 V bug, assuming that you have tested factory firmware version 72.66 and it doesn't fix the problem. But the good news is I can patch it the way that others have been done, and hopefully will have that done later today (my time). Edited August 22, 20232 yr by Coulomb

Pare o pereche ușoară de plasturi, așa că m-am uitat să văd cât de ușor ar fi. Din păcate, am constatat că această verificare este deja prezentă în versiunea de firmware din fabrică 72.66 și, prin urmare, și în toate firmware-urile corecţionate pe care se bazează, cum ar fi versiunea de firmware corecţionată 272.66. Presupun că ați testat versiunea 272.66 de firmware corecționat și lasă de dorit? Sau poate funcționează OK, dar ai prefera un algoritm „aprobat Voltronic” I installed it and it works ok...but i think that part with 0.5A is not present, can verify? It seems morr stable, find the mppt very fast, and remains there all day, but the.mppt start a.little slow, can verifiy to be like 92.05 that u modify?
August 22, 20232 yr 2 hours ago, Coulomb said: Suspin. Am căutat un link către acest firmware corectat și am fost surprins că nu l-am găsit. Așa că m-am gândit să-l atașez aici și am fost surprins să constat că nici măcar nu am putut găsi fișierul .zip. Când m-am uitat atent la fișierul .txt, văd că tocmai începusem cu asta (în martie 2023) și cumva nu am progresat niciodată cu el! Suspin. Scuzele mele. Îl voi converti într-un patch de asamblare, care este modul în care fac patch-uri în zilele noastre (ar trebui să economisească ceva timp). Deci, vestea proastă este că Voltronic încă nu a remediat bug-ul blocat la 90 V, presupunând că ați testat versiunea de firmware din fabrică 72.66 și nu rezolvă problema. Dar vestea bună este că o pot remedia așa cum au fost făcute alții și sper că o voi face mai târziu astăzi (ora mea). 72.66 is more stable but not solved the 90v problem. If u can modify is super. With 250v for twice mppts. Thanks.

Yes, I can confirm that it still has the test for 0.5 A. That's the part that I patched to 0.05 A in patched firmware version 272.66 (in the 8 kW topic; this is an 11 kW twin topic). Edit: That's all I patched (for both MPPTs); I did not change the 90 V minimum MPPT voltage threshold, and it still has the test that bypasses the "race to the bottom" code when the PV voltage is under 250 V.

August 22, 20232 yr 1 hour ago, Coulomb said: Da, pot confirma că încă are testul pentru 0,5 A. Aceasta este partea pe care am corelat-o la 0,05 A în versiunea de firmware corecţionată 272.66 (în subiectul de 8 kW; acesta este un subiect dublu de 11 kW). Edit: asta este tot ce am corectat (pentru ambele MPPT); Nu am schimbat pragul minim de tensiune MPPT de 90 V și încă are testul care ocolește codul „cursă până la fund” atunci când tensiunea PV este sub 250 V.

August 22, 20232 yr Do u think that if u not modify the 90v to 250v minimum, will work ok ? It's hard for me to know for sure, I only get so much feedback from patched firmware users. But it's the strong impression I get so far that just the 0.05 A change on its own is best, because some owners have just 4 panels in series, while others have 9 or 10. So "burning" a fixed voltage like 200 V or 250 V as the MPPT minimum is unlikely to be ideal for every user. With the 0.05 A threshold change, that seems to keep the MPPT away from 90 V when there is plenty of power available, and the MPPT is then free to find the first maximum power point. And so far that seems to be the best than can be done without a complete re-write. A complete re-write is out of the question for me, since I just don't have the knowledge and experience required, and I don't have a high voltage string or inverter to test it on. I'm only confident enough to patch these firmwares as it is because a real owner (@Georg594) was able to think of a suitable algorithm, and actually try it out on his inverter. His original patch was more extensive; I've somehow arrived at the bare minimum patch by trial and error, with feedback from owners. If you find that 72.66 works worse for you, there is also patched firmware version 92.06 to try. It's a fixed 200 V patch, as well as the 0.05 A threshold. BTW, the 250 V test that Voltronic have is different to the 200 V (and other voltages) patches. Voltronic use the solar voltage to decide whether or not to "race to the bottom"; the 200 V patch actually changes where the bottom is. Maybe it amounts to much the same thing, but I don't think so. With the 200 V patch, you can never get to the maximum power point if it happens to be below 200 V because of poor sunlight or shading. As far as I know, the latest Voltronic firmwares can do that, so 272.66 should also be able to do it. Edited October 2, 20232 yr by Coulomb added "for sure"
August 22, 20232 yr 18 minutes ago, Coulomb said: Îmi este greu să știu sigur, primesc doar atât de mult feedback de la utilizatorii de firmware corecționați. Dar este impresia puternică pe care o am până acum că doar schimbarea de 0,05 A în sine este cea mai bună, pentru că unii proprietari au doar 4 panouri în serie, în timp ce alții au 9 sau 10. Așa că „ard” o tensiune fixă precum 200 V sau 250. V ca minim MPPT este puțin probabil să fie ideal pentru fiecare utilizator. Odată cu modificarea pragului de 0,05 A, aceasta pare să țină MPPT-ul departe de 90 V atunci când există multă putere disponibilă, iar MPPT-ul este apoi liber să găsească primul punct de putere maximă. Și până acum pare a fi cel mai bun decât se poate face fără o rescrire completă. O rescrie completă este exclusă pentru mine, deoarece pur și simplu nu trebuie să cunoști și experiență și nu am un șir de înaltă tensiune sau un invertor pe care să-l testez. Sunt suficient de încrezător pentru a corecta aceste firmware-uri, deoarece un adevărat proprietar (@Georg594) a putut să se gândească la un algoritm potrivit și să-l încerce efectiv pe invertorul său. Patch-ul său original era mai extins; Am ajuns cumva la patch-ul minim prin încercare și eroare, cu feedback de la proprietari. Dacă descoperiți că 72.66 funcționează mai rău pentru dvs., există și versiunea de firmware 92.06 corectată de încercat. Este un patch fix de 200 V, precum și pragul de 0,05 A. BTW, testul de 250 V pe care îl are Voltronic este diferit de patch-urile de 200 V (și alte tensiuni). Voltronic folosește tensiunea solară pentru a decide dacă să „cură până jos” sau nu; patch-ul de 200 V se schimbă de fapt unde este partea de jos. Poate că înseamnă cam același lucru, dar nu cred. Cu patch-ul de 200 V, nu puteți ajunge niciodată la punctul de putere maximă dacă se întâmplă să fie sub 200 V din cauza luminii slabe a soarelui sau a umbririi. Din câte știu, cele mai recente firmware-uri Voltronic pot face asta, așa că și 272.66 ar trebui să poată face acest lucru. Ok. I.will try and come back with feedback

I have 64.07 down as an Axpert Max II 11 kW Twin [ edit: no, it was down as a 1 not an E ]; maybe it's an E not a II. I'll be happier when I find a way to distinguish E and II firmware from the code.

September 29, 20232 yr @Coulomb can you pls patch it ? It's on the list. Sadly, the list is rather long at present.
September 29, 20232 yr It's on the list. Sadly, the list is rather long at present. It's ok We wait till you have time. Ty very much.
September 30, 20232 yr Hi Coulomb, I have an Voltronic axpert max twin 11kw, the current version is 64.07. Which version of yours should I install to solve the 90v problem? Do you have the original version (64.07) so I can go back? Thank you very much for your work
September 30, 20232 yr You have here the 64.61 and 64.62 but its not very good. You need to wait till coloumb will patch one off them to 0.5A or 0.05A because the originals starts at 2A from the strings.
September 30, 20232 yr Ah, sì, hanno incasinato il file RAR. Il dsp.hex era per la versione sbagliata, probabilmente 64.08. Fortunatamente, sono riuscito a eseguire manualmente il passaggio finale e a ottenere il file dsp.hex 64.62 corretto. Per favore fatemi sapere se l'allegato funziona e, se funziona, se risolve effettivamente il bug bloccato a 90 V. Sarebbe fantastico avere una soluzione definitiva e ufficiale. Sembra che sarebbe facile applicarlo anche ad altre versioni del firmware, come una patch relativamente semplice. 64.62_ISOLAR SMW 11KW TWIN recuperato.zip 1,49 MB · Is this firmware that Coulomb published no good? doesn't fix the bug? Edited September 30, 20232 yr by jos89
September 30, 20232 yr This are the firmware made by voltronic and coloumb fixed it because was not good the .rar file. I will try also the 64.62 to test it but i think it will start the mppt at 2A like 64.61 firmware.
