Patching Axpert Max 3.6 with 7.2 Firmware


Recommended Posts

Hi there!

Is it possible to safely patch the Axpert Max 3.6 with 7.2 Firmware that can be found here https://www.ostrovni-elektrarny.cz/?podpora ?

Is there a list fo changes for different Firmware versions?

I have a strange thing happening at the end of the charging cycle (reaching absorption voltage) and I was wondering if the firmware would fix the problem. 

Thank you in advance!

No, you can't safely update a 3.6 kW model with 7.2 kW firmware. That's not is usually referred to as patching; patching is changing the behaviour of a program (firmware or software) by small changes, usually at the binary level, leaving the majority of the code untouched.

The Axpert MAX 7.2 91.xx firmwares are dual model, in the sense that they can run both 7.2 kW 230 V hardware, and 6.5 kW 120 V hardware. The hardware is detected at power-up by measuring the voltage on a DSP pin. When Axpert Max main firmware version 91.19 is running on 120 V hardware, it reports itself as version 45.19. The minor version numbers (after the dot) don't always agree like that. For example Axpert Max main firmware version 45.84 reports itself as 50.75 when running on 120 V hardware. 45.84 also does not support 3.6 kW hardware.

Thank you for the clarification and for not leaving it stand, so that others might not get the wrong information because of my bad choice of words. 

So what you are saying is that the 7.2/6.5kW Firmware will run on 230V and 120V hardware but not on 3.6kW? Has anyone ever tried it, or where do you get the information.

I have not seen any "official" download sites for the firmware. Is there any way to get/download the newest Axpert Max 3.6kW model firmware?

Yes.

I hope not.

Let's just say that I'm handy with reverse engineering.

There used to be, and it was very convenient. Alas, the arrival of the clone makers made it much harder to get firmware updates. But sometimes you just need them, and if so, you have to ask your supplier. End users need not contact Voltronic Power directly.

You have to ask whoever sold you the inverter-charger. They in turn contact Voltronic Power if they deem it important enough. It can be a slow process.
