I am still with the original firmware : U1 : 46.04 What would be the best firmware I could use for it ? (to maximize of course low light performances) I believe you should be able to use any of the 90.06 patched firmwares. Unfortunately, I don't have any 46.xx firmwares to be totally certain. If 90.06 isn't the right firmware, it should just not update, it should not brick your inverter.

Can help me with modify with 300v and 350v pls ? If its not getting u a lot of time.
February 21, 20233 yr 8 hours ago, add1c7ed55 said: Can help me with modify with 300v and 350v pls This is patched firmware version 292.04, based on factory firmware version 92.04 for the Axpert Max 1 8kW with '29066 processor. It is the same as patched firmware version 92.05 (sometimes badly named as 92.04 patched), except that instead of using a minimum MPPT voltage of 200 V, it used a minimum of 300 V in MPPT1 and 350 V in MPPT2. Hopefully it's not too hard to swap PV inputs between MPPT1 and MPPT2. Now that I'm set up, it's not too hard to patch different minimum MPPT voltages. It also fixes the premature float bug. As always, use only with the intended model, not even an Axpert Max II 8kW with the round colour display. Your existing firmware should be 72.xx, 92.04, or 91.04. Since the minimum MPPT voltage is now 300 V, you should have enough panels to well exceed 300 V in good lighting, and well exceed 350 V for MPPT2. Use at your own risk.

Este la fel ca versiunea de firmware corecţionată 92.05 (uneori denumită prost ca 92.04 patched), cu excepţia faptului că, în loc să folosească o tensiune MPPT minimă de 200 V, a folosit minim 300 V în MPPT1 şi 350 V în MPPT2. Sperăm că nu este prea greu să schimbați intrările PV între MPPT1 și MPPT2. Acum că sunt configurat, nu este prea greu să corectez diferite tensiuni MPPT minime. De asemenea, remediază eroarea prematură a plutirii. Ca întotdeauna, utilizați doar cu modelul dorit, nici măcar un Axpert Max II 8kW cu afișaj color rotund. Firmware-ul dvs. existent ar trebui să fie 72.xx, 92.04 sau 91.04. Deoarece tensiunea minimă MPPT este acum de 300 V, ar trebui să aveți suficiente panouri pentru a depăși cu mult 300 V în condiții de iluminare bună și pentru a depăși cu mult 350 V pentru MPPT2. Folosiți pe propria răspundere.

Pls tell me if i put the 350v and sometimes will have under 350v..what will happen?

You will get reduced PV production, possibly zero. 4 hours ago, add1c7ed55 said: i would try firmware with 300v on twice mppts and another patch with 350v on twice mppts... I always thought of this as an experimental firmware; even 300 V seems too high to me. But the best way to find out is to try it.
February 22, 20233 yr 4 hours ago, add1c7ed55 said: This is the voltages today. Sunny weather. Thanks. You do seem to have plenty of voltage in good sun. How was the current and/or power? Particularly MPPT2 after about 4pm, when MPPT1 went down to around 300 V, and MPPT2 to around 350 V? I'm guessing with the dip around 5pm, you would have gotten very little from MPPT1, and nothing from MPPT2.
February 22, 20233 yr 9 hours ago, Coulomb said: Mulțumiri. Se pare că ai multă tensiune la soare bun. Cum a fost curentul și/sau puterea? În special MPPT2 după aproximativ 16:00, când MPPT1 a scăzut la aproximativ 300 V și MPPT2 la aproximativ 350 V? Bănuiesc că, în jurul orei 17:00, ai fi primit foarte puțin de la MPPT1 și nimic de la MPPT2. Here is the graph.
February 22, 20233 yr 2 hours ago, add1c7ed55 said: What voltage do u think i need ? Well, in sunny weather, 350 V does seem to work better (assuming it's PV2 with the higher power, I can't figure out which is which on the power graph). The power output seems well matched 9am-1pm, so the strings seem to be comparable. But perhaps wait for a cloudy day to see if performance is really poor for MPPT2.
February 22, 20233 yr 5 hours ago, Coulomb said: Ei bine, pe vreme însorită, 350 V pare să funcționeze mai bine (presupunând că este PV2 cu putere mai mare, nu îmi pot da seama care este care pe graficul de putere). Puterea de ieșire pare bine potrivită între 9:00 și 13:00, așa că șirurile par să fie comparabile. Dar poate așteptați o zi înnorată pentru a vedea dacă performanța este într-adevăr slabă pentru MPPT2. One of the mppts is a little shadowed, and the other mppt on the sunrise is less luminated cause the sun is rising...probably 350v is a little more...can we try 320v? I have all the graphics in all day...what to verify on the rainy days?
February 23, 20233 yr 5 hours ago, add1c7ed55 said: what to verify on the rainy days? With the patch in place, just notice whether MPPT2 is doing way worse than MPPT1 on rainy or dark cloudy days.
February 23, 20233 yr 5 hours ago, Coulomb said: Cu plasturele la locul lui, observați doar dacă MPPT2 se descurcă mult mai rău decât MPPT1 în zilele ploioase sau înnorate. No, its a little difference only, not big.
February 23, 20233 yr 4 minutes ago, add1c7ed55 said: Nu, este doar o mică diferență, nu mare. I verified on graphs, mppt1 is.with "problem" not mppt2, goes in 200v in the afternoon for 5 seconds, and after that goes up again, this makes a lot of times In all day, the voltage isnt never under 300v on each mppt.
February 23, 20233 yr 6 hours ago, Coulomb said: With the patch in place, just notice whether MPPT2 is doing way worse than MPPT1 on rainy or dark cloudy days. Here are 3 days cloudy and rainy. Mppt2 produce a little bit more than mppt1 but is a bug of this.inverter, all 8k make this bug even i change the firmware.

I flashed successfully my axpert max 1 with the one believed to be 100V and reported as 90.09 in U1. The problem is super low light seems to perform worser thant the original firmware .... Ok I will try to play with the 90.06 & 90.08 as well to compare
February 25, 20233 yr Pffff .... I downgraded to some 90.08.... and now an information from QPIGS is no more correctly decoded ... i.e. the switch_on status Edited February 25, 20233 yr by SeByDocKy

The 90.xx series firmwares are trickier even than normal; you can't tell if one is later than the other by the minor version number (the number after the dot). Some of them are for totally different models, some might be for Twin models, etc.
February 27, 20233 yr I installed a version that is working fine. I retrieved my QPIGS information (usefull for some automations). Seems I got some improvement in low light conditions.... so I stop to complain
March 11, 20233 yr On general remark with new firmware (90.09), I noticed fan behaviour is different : smoother for sure but in average , the internal temperarature increased abour 3 degrees .... I am worried for summer time.... Edited March 11, 20233 yr by SeByDocKy
