Hi all

For sake of simplicity I'd like to just put firmware download links in one place.

My contribution:

CPU1 72.60 Firmware

CPU2 4.10 Firmware

The files are hosted on S3 and won't get removed.

These are thanks to KnottyBuoy who posted them in two other threads

 

If you have future files to host, PM me, I'll add them to my S3 bucket and the first post with credits to you.

Really the only benefits of using S3 is that the files won't get removed, no need for logins and lastly S3 is fast (like 5% of the internet hosts something on S3)

I rented a 5USD/month server at DigitalOcean to host my stuff. Also intend using it as a VPN for NetFlix at some point. Safer than using someone else's proxy. :-)

Hi.  I hope you can help.  I got 2 axpert 5kva inverters in parallel. (Bought in 2017)  Firmware 52 30.  Recently the load between the inverters started to differ when it is in overide mode. So that one will overload and the other will be on 25%.  I was told to do a firmware update but nobody wants to tell me what firmware to update it to.  And where I can find it.  Would you be able to point me in the right direction.

That doesn't sound like a fault that a firmware update would fix.

Those inverters must have been old stock back in 2017. They will be PF0.8 models; the latest factory firmware for those would be 73.00. There is fully patched firmware version 73.00e as well. You can find links to these and much more at the PIP-4048MS and PIP-5048MS inverters index. There will be no need to update the SCC firmware, especially if you opt for the patched firmware.

Thank you so much.  Sorry about the similar question I asked later.  Still new on this forum.

Lastly.  If you say the load difference between the two inverters is not firmware related.  What could it be.  My load sharing cable are connect as per instruction manual.  What else could be the problem.

The output wiring, including the output breakers.

Edit: or possibly something on the main board, between the inverter output and the output terminals. For example, relay contacts, quick connectors on the PCB, cables loose in AC-out terminals, and so on. When you have an imbalance, you might be able to find voltage drops across cables, breakers, etc. on the one that is providing the lower share of the load.

Thank you very much Coulomb.  I appreciate your guidance.

Hi.

I managed to get my loads balanced etc.  I tried to flash the inverters with the flashing tool to install the firmware update.  Not sure what went wrong but the tool picked up com4 and opened it.  It did fail to communicate after a few minutes and I eventually left it.  Did I do something wrong or is there software I can use to do the firmware upgrade?  I was told to use Watchpower but my inverters are not on Wifi.  The suppliers in SA are not to helpfull and want me to take them off and send them in for the upgrade.  With the load shedding, we get it will not be possible to take that route.

The reflash tool just picks the first com port that appears to be available. You have to know what port your USB to RS-232 adapter is on, and change the selection to that port.

Thank you once again for you are always willing to help.

Does anyone have axpert max 7.2k firmware updates? Got the typical no comunications with pylontech bms.

Best regards

You didn't say if you wanted display or main DSP firmware. If the former (the display handles 99% of the BMS comms), I found only the one below in the files section:

It's from June 2021, so 15 months old as I type. I would think that most comms errors with Pylontechs are due to cable problems, rather than firmware.

 

We meet again Coulomb, hope everythings allright on your side.

Well i assume the display module carries all major comms, but since i have no idea about how the software runs on these inverters i though id better ask the general question.

As for the cables, i already tried every combo(using the recomended pinout) i could think of, plus the dealer sent a custom cable with only 2 wires crimped on one end, pin 3>8, pin 5>7, and a stock reversible cable as well.

Also there is an issue with the soc reading, while the batteries are full led lit, the inverter says they are at a max of 53%, im assuming its the firmwares fault too.

Right now at 2am soc is 21% at 49.8v no loads active.

Toughts?

Cheers

Until the inverter talks to the battery BMS, it can only guess the SoC based on battery voltage, and with an LFP battery, that guess will be terrible. So that's not firmware. 

What display firmware are you running now? 

U1 69 01

U2 112 14

I think this is it

Ah. Then 12.11 is too old for you anyway. Since then, I've seen 112.19 and 12.21. 12.21 definitely seems later than 112.19; I have no idea why it drops the leading "1". I've juust uploaded 12.21. I doubt that it will fix your problems, but at least it's fairly easy to eliminate the firmware as a factor.

 

Thank you Coulomb, i will try to backup the current firmware just in case before i upload the new one.

Hope to come back with some good news

 

Cheers

Well guess what, it all worked!

Bms comms restored and therefore the soc is now showing as it should appaerently. 

It is now 11pm and the soc is 77% at 49.5v, discharging at 4A(~230w) just lighting.

I must thank you once again for your support on this one.

Still, i must confess i almost wet my pants when i saw the display going dark 😆 as i read somewhere it could happen if the upload got interrupted or something gone wrong 😅

Will monitor the system closely for the next few days and post if i find anything odd.

Cheers!

I'd be interested to learn how you accomplish that. 💭

Yeah, i after realized that tool has no option for that..

That would really be something else 😅

Hallo. I have a mecer 8kw inverter. Quite regularly (once a week) it shows error f55 and stops. Have to switch it completely off and on again. Is there newer firmware or something that perhaps will fix that?

Its currently cpu1 on 72.01 and secondary cpu on 112.14.

Not sure if firmware on these are available anywhere?

That's quite old; about 3 years old now. Fault code 55 is "over DC voltage in the AC output", which does not sound like it might not be fixed by firmware. But it's free, so you may as well try it.

The latest 72.xx firmware for Axpert Max E 8kW '28066 non-Twin is 72.08. But it does not have the "presumed good" MPPT logic. So you might like to try 72.75, which does have this logic (so low light PV production should be OK), and it even has the QDOP command for SoC% values for three settings (mainly for other readers). If you need the absolute best performance in low light conditions (cloud etc), then consider patched firmware version 272.66.

Not to toot my horn too much, but the best way is to post on this forum with your existing firmware version (as you have, thanks!), and hope that I see and respond to your post. I collect all the Axpert firmwares that I can find, and explore their internals to a limited degree. So I can figure out what is the latest downloadable firmware for a given model (series, type of display, power rating, chipset, whether Twin, Duplex or neither) with particular features (e.g. good MPPT logic), search for it, and post a link to it.
