Hello!

I'll write it down here too, in case this is a solution for someone

Thanks for your help and the video too.
I also managed to solve it by connecting the pylontech with a solar assistant running on a raspberry pi and controlling the inverter that way.
I would have used the firmware update only as a last resort, but I managed to buy an rs485 - usb cable.
Thanks again.

You can't update the display firmware (e.g. in mcu.hex) via the USB method, only the main (DSP) firmware. The USB reading happens with the display firmware; during display firmware updating, the display firmware gets erased, and gradually rewritten, likely with the USB code in a slightly different address. So display firmware has to be via RS-232.

Sorry I didn't pick up on that earlier.

 I just noticed that we never announced in this thread, the September 2023 release of our fully patched firmware for the Axpert King, kindly sponsored by Power Forum member @Youda. See https://forums.aeva.asn.au/viewtopic.php?p=97712#p97712

It says "beta", but it's thoroughly tested by now and no problems have been reported.

[Edit: Calvin has since reported that Dynamic Current Control does not work with solar charging in this beta patched firmware. It only works with AC charging. The SCC continues to use the EEPROM value of maximum charge current. Calvin reports that all other features work as advertised in his 3-parallel-machines setup.]

How did you fix this ? I am stuck at the same point ...

As I said above, the poster you were quoting was trying to update the display (U2, MCU) firmware from USB, and that can't work. If you are trying to update display firmware, you'll have to use RS-232, as per the unofficial firmware upload instructions.

For those who need the latest factory firmware that I'm aware of, as of this post, see below. For the latest fully patched King 1 firmware, see Weber's post above.

This is unpatched main firmware version 72.05 for the Axpert King 1 (standard) 5 kW. Do not use with any other model, not even an Axpert King II 5 kW (high PV voltage model). Hex file is dated 17th Feb 2024. Use at your own risk.

Firmware upload instructions for models with a removable display.

Rar password is 111.

AxpertKING_5KW_STANDARD_72.05 pw 111.rar

What would be the right order to update? First MCU and then Main or opposite.

I have a standard King running 2.66a on MCU and 71.97 on main.

I don't think it makes any difference. 

Thanks Coulumb,

 

I have 2x new Kodak OG PLUS 5.48 models (King Low Voltage MPPT) will be configured on parallel with Pylontech batteries.  (seperate ICC software similar to solar assist)

 

Just confirming if the versions below are the most recent and compatible with eachother?

Main DSP 72.05  (As per this thread)

MCU 02.83a   (From https://forums.aeva.asn.au/viewtopic.php?p=87767   Only see 02.81 on this thread)

 

Anyone that has done this recently ?

Hi @Marius2001. No, those are not the latest, nor are they compatible. Sorry. You can only use patched display (MCU) firmware with patched main (DSP) firmware having the same patch letter and released together. The latest is here:

https://forums.aeva.asn.au/viewtopic.php?p=97712#p97712

If we release future patched versions, you will be able to find them by going to the index post (the first post) of that thread and looking in the Firmware section.

72.05 is indeed the latest factory (not patched) King 1 main firmware that I'm aware of.

MCU 02.83a

This is the latest fully patched display firmware for the King 1s, but it can only be used with a fully patched main firmware such as 72.00a, as Weber points out above. It's based on factory display firmware version 02.83, which is not the latest. The latest display firmware that I know of is 02.87, available here (along with 72.05).

Thanks  - I've not upgraded as yet as the "factory" firmware is v72.02 and display 02.83 .

This seems quite up to date, will upgrade once I see that inverter jumps to grid unnecessary.

 

@Coulomb you've also assisted my in the past on my Axpert 4000w inverters - one stopped working and I've therefor replaced both with these King models - cost of repairing almost the same as a new one hence the "migration".

 

Very happy with lower voltage MPPT - still running my setup with Raspberry PI ( ICC software) that is handling communication between Inverters and Pylontech batteries.  I've not installed direct RS485 cable - actually prefer the manual way to ensure that Pylontech are not charged more than 52.5 volts.

This is no longer strictly correct.  I have 3 Kings in parallel and the Dynamic Charge Control not only does not work but causes wrong data - I reported the symptoms to @Coulomb some time ago.

Having said that, all the other features work very well, exactly as advertised.  Great improvement over the normal firmware.

 

Anyone know which are the latest main and DSP firmware for the 7.2 kW version? And where to download them?

Yes, Coulomb knows 😎!

Main and DSP firmware are the same thing. The main/DSP firmware version is also known as the U1 version number.

You didn't say what chipset you have, or give an existing main firmware version. I assume you have the Axpert Max E 7.2 kW non-twin, even though this is a King thread.

For '28066 chipset (69.xx main firmware), the latest is 69.70, dated 2024-3-06, and this has the presumed good MPPT logic (no stuck at 90 V issue).

For the '2809chipset (45.xx main firmware), the latest is 45.13, dated 2023-9-05, and unfortunately does not have the presumed good MPPT logic.

As for display firmware, you are presumably running 12.xx, and the latest for that is still 12.28 (a year old now).

Edited November 7, 20241 yr by Coulomb

Users of Coulomb and Weber's patched firmware 72.00a beta for the Axpert King 1 or PIP-MK, please note: The rarely-used feature "Dynamic Current Control" does not work with solar charging. It only works with AC charging. The SCC continues to use the EEPROM value of maximum charge current. I have updated the documentation accordingly.

Many thanks to @Calvin, for reporting this. Thanks also to Calvin for reporting that all other features work as advertised in his 3-parallel-machines setup, as we did not have parallel Kings for testing.

Thank you, appreciated! 

My one inverter is 69.xx and the other 45.xx. 

Assuming the DSP firmware is not cross-compatible? Cant load the 45.xx onto the one with 69.xx? 

Not good news - I was hoping to connect them in parallel.... Is this still possible?

They are not cross compatible in that sense, no.

Yes, it should still be possible to parallel them. It's best if the firmware versions are fairly close to each other, in the sense that they were compiled from largely the same source code, but unfortunately Voltronic don't help with this.

Just updating to the latest you can get is probably fine. But if  you are concerned, ask your supplier(s) for the latest firmware update files.

Thank you, will give it a go, hopefully they can talk to each other. I've got all the parallel cables etc. 

One is a Synapse and the other a Kodak - my supplier is Facebook Marketplace...

Oh. Synapse are not genuine Voltronics, as far as I know. [ Edit: Wrong! I was confusing with Synergy! Sigh. See a few posts down. ] I think that they somehow effectively forked Voltronic firmware, and now may have diverged enough to make paralleling with a genuine Voltronic (such as a Kodak) unsafe. Sorry, I don't recommend it. 

I assumed that they would be two genuine Voltronic models, regardless of branding.

That's one of the limitations of such suppliers. You are effectively surrendering the right to support.

Hi, just a correction that they are. They are supplied by Rubicon who has an agreement with Voltronic power. We've had support from the factory directly to try deal with the dip and freeze problem on the kings (Synapse 5.0k+).

Firmware for Synapse can be found at https://ftps.voltronic.com.tw/R/Rubicon-553AF2CC1A6A43989371/

Ah! My bad. I keep confusing Synapse and Synergy. Synergy are the clones I was thinking of. Sigh.

Having firmware in the Voltronic FTP domain certainly clinches it.

So @Pieter v D, there should be no problem paralleling these.

If you're not concerned about the stuck at 90 V issue, it may be safer to parallel 45.13 with 69.07, since these are both from early September 2023, so they are probably compiled from the same source code (and so should operate identically on their respective processors).
