Press the up or down arrow buttons on the inverter until the top row shows "U1", then reply with the numbers on the middle and bottom row. My inverter shows: U1 69 61

Hi Arne, I can highly recommend the patched version 269.61 - my Kodak OG 7.2 just works perfectly with this firmware.

Ahhhhh now I understand, thanks. Shyoh good luck with keeping track of all the versions 😀 At least there is no hurry for me to get a patched 69.06 now but I will definitely test it for you when you get to it.

OK, using watchpower, I applied defaults, it told me that it failed, and no settings were changed, so I tried sending PF using the communication tool, and that gave me a NACK, and no settings were changed, I then just randomly tried to set the max discharge setting again, it is now saving this setting. And now the EEPROM failure warning is gone. I guess I will try this again after the next firmware upgrade 😀

Sorry I meant non-twin from your list of "What axpert firmware is that" (forums.aeva.asn.au/viewtopic.php?p=95278#p95278) where you listed the 69.61 firmware being for "69.61 Axpert Max E 7.2 kW '28066 non-twin. Fixes EEPROM error warning with 69.60." I was thinking it refers to twin versus non twin MPPT and since I have twin MPPT it might not be right for me? Regarding the EEPROM warning, I noticed that the maximum discharge amps setting does not appear to save from the display, I checked the setting from the PC software and the setting reverted to unlimited. So I am wondering if my display version (12.21) is not quite matching the cpu version's settings. Either way, I had a warning on version 69.05, when I upgraded to 69.06 the warning disappeared, and now on 269.61 the warning is back. The value is not changing so I doubt it would be a timing thing, I could be wrong.

@Coulomb 269.61 works beautifully in the early morning! You guys do amazing work. I was a bit confused on the list of inverters & firmware about the word "single" thinking the firmware might not apply to my Kodak OG-7.2, what does "single" mean? I have an EEPROM warning in Home Assistant again, but it seems to be harmless. I will try a factory reset to see if that resolves the warning.

LOL unwanted bonus software. @Coulomb Pretty pretty please! 😀 I am not too much in a hurry, so whenever you reach this one on your to-do list. Maybe I should try 269.61 in the meantime, Thanks!! They should pay you guys for fixing their bugs, and give you the source code to make things easier! 😀

Hi @Coulomb I recently bought a refurb Kodak OG-7.2 twin MPPT, with firmware 69.05 loaded. yesterday I upgraded to 69.06, it resolved an EEPROM warning, but I see in the early morning I still have the following problem: For about an hour up until the PV current reaches 2.8A, the PV voltage is clamped down to 97-107V. If I switch the PV breaker off and on again and the current is 0.6A or greater, the PV voltage jumps to 315-325V and the output is what I expect. Is there is way to fix the firmware to improve this? Or must I make peace with this? I was hoping I can create a Home Assistant automation to change a setting on the inverter to switch the MPPT charger off and on again, but nothing seems to do the trick, unlike my previous MKS 5kva clone, changing the charge voltages, or even switching to grid charge only does not give the panels a breather. Is it a mission to be able to view the firmware file in assembly language? @pongo Thanks for sharing 69.06!
