Can someone please provide me with link to stable current OS for Kodak king 7.2

My OS has low charge rate and I need to update it to get bit better throughput

The latest available Axpert Max E 7.2kW firmware is either 45.14 or 69.70 depending on which DSP chip your inverter has.

What is the present main (U1) firmware version?

Will check everything later and post

And thanks for responding

Sorry, I've been really busy lately. I see that 45.14 is not widely published.

[ Edit: There is a third firmware, the "display" or "communications" firmware, that could likely do with updating as well. Version 12.30 is probably the latest for your model, and I see that's not widely published either. Let me know if you feel the need for that. ]

This is main (U1) factory firmware version 45.14 for the Axpert Max 7.2kW '2809. Do not use with any other model or version.

Use at your own risk. The hex file is dated 05/11/2024.

Firmware upload instructions for models with a removable display.

This firmware processes the QDOP command, so with suitably recent display firmware, it should support SoC% for settings 12,13, and 29 when connected to a suitable battery's BMS.

Thanks much appreciated

Ran upgrade using USB mini port twice

It says usb then yes then I press yes and it then takes the no away but sits there for 15 minutes

Then goes back to original start screen but no buttons work

Left that for 10 minutes and nothing

Rebooted and old version showing

What am I doing wrong

And does anyone have the kodak serial cable I can borrow or buy so I can try it from PC instead

This is secondary (display, U2) factory firmware version 12.30 for the Axpert Max and Axpert King II (NOT the original King 1), non-Twin. Do not use with any other model or version.

This firmware processes the QDOP command, so with suitably recent main firmware, it should support SoC% for settings 12,13, and 29 when connected to a suitable battery's BMS.
