How many Pylontech US3000 units can I connect to an Axpert VMIII?

As many as you want. One is pretty light; 2 minimum preferred.

Hi

My WKS EVO 2 seem to be a Axpert VMIII

My CPU is 41.03

Secondary CPU is 02.00

Secondary Bluetooth 00.21

Do you think it's good idea to upgrade with the 41.17 as you you can find in the link above ?

This firmware is good for to use with Li-Ion battery ?

Thanks for all

Thank

I've done it perfectly with USB key, now i'm waiting after USB-RS232 dongle to upgrade MCU to 2.66

Do you know if it is possible to connect US3000 and AGM batteries to the same Axpert VMIII unit so that US3000 is used on a daily basis and AGM is only used as a backup power in case the grid goes out?

 No. Mixing battery types like that is not recommended at all. US3000 is good for daily use and backup. No need to have other types of batteries connected.

Patrząc na https://www.ostrovni-arny.cz/support/Axpert/FW/ najnowsze oprogramowanie, widzę, że wersja VMIII jest elektro jako 91.20, co bardzo różni się od oprogramowania 41.16 powyżej. Czy ktoś ma na wytłumaczenie?

Translated to English:
"Hello

Tell me gentlemen how to install it? I downloaded the rar file now what should I do on the subframe to make an inverter under usb?"

You will need software to "unzip" the rar file. 7-Zip for Windows (you need a Windows computer anyway) is free and can do this.

Google translation:

"Gentlemen, do you work with wifi connected via RS232 port?

After connecting, nothing happens for me, maybe someone knows what to do with it?"

I don't use Wifi for RS-232, so I'll leave that to others.

I'm having extreme difficulty understanding your second post. I assume that you successfully installed firmware version 41.17? This seems to be the latest firmware available for Axpert VM III models (but not Axpert MKS III models; the title of this topic is ambiguous).

[Pepnponcho]

Hi all!

After reading up on the firmware update, i decided to take the plunge today as the fan on my VM iii was on 24/7 and the warning 69 came up whenever the batteries were full. 

Tried first 41.17 using USB to micro to connect, gave a 'read error'. Tried several times more, but still same error. Also tried the 91.20 which sometimes started to install but sooner or later got another read, write or UPS firmware data error. Inverter meanwhile is giving warning 32 and doesn't want to come on. 

This system has 3 pylontech 2500c batteries, 5 x 395W panels and the VM iii. 

Does anyone have a clue what is going wrong and/or how to fix it. At this point just restoring to factory setting would be great. 

I've added some pics of the errors and the original firmware. It seems like u1 was on 47.00 which I have not seen anywhere else? Does this make any sense to anyone? 

Tomorrow I'll try using the connector that came with the inverter (USB-RS232) if i can find a dongle to USB somewhere. Was there another method using a USB stick? Is there a manual somewhere that explains that process? Is there somewhere i can get firmware 47.00 to restore it back to factory settings?

[bib60]

Hi, if you are using USB Stick you don't need to use software.

Just put your VM3.HEX file on the usb stick Fat 32 and use USB OTG method with panel keys

I don't know why people are so worried about warning 69. It's basically saying "warning: your battery is full, I can't charge it any more, the BMS has said no more charging". Warning 69 has been removed in the latest removable display firmware, probably because it causes such confusion and needless worry.

The next problem is that I can't even figure out what model you have there. The reseller has been unhelpful with the model name: "Inverter VM III". We've been assuming that it's an Axpert VM III, but it's recently manufactured (2021 05), and there is now such a thing as an Axpert MKS III, which is an MKS II with a removable display. These are very different internally. The fan being on continuously makes it sound more likely to be a VM III though. I don't know much about the MKS II, and even less about the MKS III, so I have no idea what the fan behaviour is like for those models.

It also doesn't help that Voltronic's firmware version numbers are all over the place, and that they don't document what firmware is for what hardware.

So you're on the bleeding edge here.

Can you explain exactly what you did? Did you use an on-the-go cable? Plugged it into the left port (marked with USB and two arrows)? FAT-32 format? Copied just VM3.hex to the root folder?

Did you get a paper manual with the inverter? Does it mention a .hex file?

If you did all this right and it doesn't work, this is an indication (not really definitive because so many things could go wrong) that you don't have a VM III.

Starting but not finishing suggests a problem with the removable display. Voltronic have a habit of using marginal opto-couplers, which work acceptably at 2400 bps for the commands, but don't work reliably at 9600 bps for firmware updates. So it might be possible to borrow a removable display, or get it replaced.

Also, the firmware update program appears to be vastly different to the simple ones with the spelling errors (e.g. "frimware (sic) sucess (sic)". It might be that you need to use an older firmware update tool.

Unfortunately, these inverters aren't like internet routers, where there is room for two firmware images. Once firmware updating is started, it has to be completed, as one of the first steps is to completely erase the firmware (apart from one small part, the bootloader). So there is no going back.

One possibility is that it's an MKS III firmware, which is no new that no-one has a copy of it. If that's the case, it's scandalous that the firmware update process even got started.

? How are you doing the updates without that cable? Is this with the USB on-the-go cable after all? I thought you could not get that working?

Quote

Was there another method using a USB stick? Is there a manual somewhere that explains that process?

So now I'm completely confused about what you are doing.

The VM III manual unfortunately says "If firmware upgrade is needed, please check with your dealer or installer for detail instructions." See attachment.

I doubt that this will help, but you might get some clues for the RS-232 update process here:

Is there somewhere i can get firmware 47.00 to restore it back to factory settings?

There is nowhere online that I'm aware of. Your supplier should be able to provide a suitable firmware update file for your model. This is probably your best bet. Unfortunately, it is likely to take some time, and in the meantime, I assume that your machine isn't usable.

 

 

 

[Coulomb]

The Axpert King manual is slightly more helpful. But I know that the VM III and King operate differently with respect to firmware updates, so the details may vary.

[ Edit: see also this post by Calvin, on updating via USB on an Axpert King. ]

First of all, thank you for replying to all my questions - if only the Voltronic or the shop I bought it at were 10% as helpful

I get that but this was an installation for a client and it's not great to have to tell them to ignore a blinking sign with a warning when you just installed their system. Having said that, the main problem was the fan which was on 24/7 at the highest speed making a ton a noise.

It's been sold to me as an Axpert VM iii by a large construction chain here in Spain (Bricomart) - https://www.bricomart.es/inversor-cargador-48v-5kva-vm-iii-axpert-10876754.html

There is no Fat-32 format USB entrance to my machine, just a micro USB. Is there one on your machines? Therefore I used a charging cable for a mobile phone to connect the USB of my PC to the Inverter's micro USB port. Then used the reflash programme and firmware version found here: https://www.ostrovni-elektrarny.cz/support/Axpert/FW/

Since my post I tried a few other versions too (41.16, etc), none of which had any more success. The slightly weird thing is that sometimes the update starts and the tool starts counting read and write operations up to 20 or even 38 but then I get the same 'read err'. Even in the errors there is variation, sometimes it is a pop up with a 'ding' sound, other times it's just a line of text in the reflash tool. The wording can also very, it can be a read error, write error, UPS firmware data error. There is 0 consistency and I can get different combinations of the above when trying to install the exact same firmware version...

For now, I bought another machine to install at the client and the faulty one is back at the shop. We'll see if they can make some sense of it and repair it. If they do I will definitely share the solution here.

Take care, some USB charger Cable is not able to carry data !!!

Ah!

That explains a lot, except for why it appeared to do anything at all. My best guess is that random data from the USB port tricked the reflash tool into thinking that there was something responding. The good news is that therefore the customer's machine isn't bricked, as I first thought that it must have been. Please correct me if I'm wrong there 

The micro USB port on the removable display is not for reflashing from a PC; it's for flashing via a USB thumb drive / stick. But most micro USB cables have a type A male plug on the end; you need a socket to plug the USB drive into. That's called a USB on-the-go cable, for reasons not relevant to this discussion.

The other problem as @bib60 mentioned is that inexpensive phone charger cables either don't have data wires at all, or are notoriously unreliable when carrying important data (such as data for flashing an inverter).

I think you'll find that the proper methods (using USB to serial or the USB-on-the-go cable) will work much better.

But there is still the question of whether any of the available firmwares are suitable for that machine. I'm concerned about the original being version 47.00, when no other 47.xx versions have been seen.

Ok well that's probably why I got different results then in my different attempts, there is some data being transferred but sooner or later it loses connection giving the data errors. 

As said it's with the shop now, see if they can make any sense of it. If they hand it back to me in the state I gave it to them I will have to try the USB on the go cable. But I will push for the store to ask their supplier to confirm what this 47.xx software is all about. It clearly doesn't sort out the fan or warning 69 issues so why is there a different version at all?

Just read the release notes! Oh, wait... 

Perhaps I should have mentioned, the warning 69 fix is implemented in the display firmware, not the DSP firmware. The display firmware handles all the communications with the BMS via RS-485 or other cable, and actually raises the warnings associated with the BMS.

Thanks for your explanation about the customers not understanding the warning. It sounds like removing that warning altogether is the best for those sorts of customers, and probably best overall.

As for what firmware version 47.00 is all about, I have no idea, and am curious to learn about, if possible.

[lukasz]

I upgraded 41.17. I tried various usb and only when I connected a 512MB pendrive through the adapter it worked. 32gb was not working

[Faizel]

What is the firmware for a lux inverter 5kva for setup.?

[Lunga]

When the main power goes off the inverter runs for about an hour then the voltage on the battery drops to 43.7 v dc... when that happens it continuously switches off
