For curiosity, I flashed the 60.10 firmware with MCU 12.15 to my Axpert VM III Twin. Two new programs were added, 42 and 43 which I asked Voltronic about them and their response was:
Prog. 42 & 43 are used for below meter alarms. Prog. 42 for “Earth alarm” and Prog. 43 is for “Reverse alarm”.
And what mentioned in the updated user manual for VM III Twin about the two programs is:

I'm trying to understand the concept, so is there any thoughts?

I don't understand what the mission of this addition is Is the second outlet fed if the city current comes in? What does the ground have to do with this??

Hey there! Quick question—when you said “mission” of the addition, were you referring to its purpose or maybe something more top-secret? 😄

Since I noticed that the grounding (earth) feature seemed a bit confusing for you, and I’ve seen you in local Facebook groups claiming that miswiring the Felicity battery BMS pins could fry the battery even it is just communication cable, it might be a good idea to revisit some basic electrical concepts. A solid understanding of these fundamentals could add a lot of value to your passion and practical experience which I truly admire 🎩.

To explain the feature more clearly:

Program 42 monitors your system’s earthing. If there’s a grounding problem, such as a missing or faulty earth connection, it will trigger the alarm to prevent electrical hazards, like shocks or equipment failure. Program 43 warns you of reverse power flow, which could happen if the power is flowing back into the inverter instead of out. This reverse flow can damage equipment or cause inefficient system performance, so the alarm helps avoid that risk.

Maybe the differences in firmware version numbers are based on the reseller brand names (mine is TripleA with factory firmware 60.08)

My apologies for the late reply; somehow I missed a block of messages a week ago.

84.00 is a very weird version number, I'll agree. I have no 84.xx at all in my collection. My wild guess is that they wanted a "very different" firmware version number for a "very special" firmware modification. I don't believe that it has anything to do with your inverter's branding. Though indeed some brands (e.g. Aerox) get special firmware and even special displays with custom icons.

84.00 seems much like the other 60.xx firmwares so far. So I'm sure it will be compatible with your machine.

I do really appreciate if you can have time to look at firmware 60.10 before I update my inverter.

60.10 also looks much like the others. It's a non-experimental version, so it gets a minor version number (10) that is < 60.

Is there anything specific you want me to check? The MPPT code is identical for all these firmwares.

Huh. This is very hard to follow. Are these LEDs on power meters? Does "reverse" refer to reverse power flow, i.e. accidental power export? [ Edit: I hadn't read esmail-kassir's last post; it seems that it might be about power flowing into the inverter's AC-out port. ]

Hopefully I'll get some time to figure out what these settings/indicators actually do over the next few weeks.

Just concerned if any major updates are compared with the previous ones, except the new two programs 42 and 43.

Btw, this 60.10 firmware doesn't have the low-speed fan feature.

Yes, maybe it is something related to the alarms on the power meter, but the point is what those numbers are. Is it Volts or Amperes or seconds or just a value indicator?

In program 42 when the grid is on, the upper number change to 8 and sometimes to 5 or 2 (as I observed) and 0 on the bottom which is adjustable with the mentioned values in the user manual.

Is there a way to extract firmware image from the inverter? For backup reasons in case other fw were worse

Short answer: no.

You need a 128-bit password (32 hex characters), plus special hardware and software, though the software often comes with the hardware, and it's not particularly expensive. But without the password, it simply won't work.

The best that you can do is to find the firmware update file for your existing firmware, or failing that, the closest one to that.

i have check and adjusted the 42 an 43 settings, basically without these setting inverter during day time when solar is avaialbe inverter  turn on the Earth and Reverse light in utility meter, its not feeding the electricity to the grid still its TURN ON the Led of reverse and on utility meter , i have adjusted both these setting now the LED is off , its good feature indeed!

Detailed instructions on how to update/upload firmware of Removable and Round Display inverter models, posted by @Coulomb:
https://forums.aeva.asn.au/viewtopic.php?p=87767#p87767

I am a little bit confused

This guide says I should disconnect everything and keep only battery connected, while the document provided with the update file by voltronic says I should disconnect everything but keep ac connected

Also, how long does the firmware update usually take (dsp and mcu)

You can update the firmware with both AC and Battery connected, just completely turn off the solar power and the loads.

The update time is about 6 to 8 minutes for each (DSP and MCU)

just to make sure I understand correctly,
can I update both dsp and mcu on battery only without ac connected? because ac is not stable and gets cut randomly.

I emailed voltronic and they sent me the latest frimware for my inverter
my inverter is renovo vm3 4k twin
current fw is 71.01 and the one they sent is 71.03
as it has been stated before the first number seems to have nothing to do with fw version or date, it might be an identifer for the brand selling the inverter.
if that is indeed correct, I wonder if the inverters have some differences in components for each brand
because why would they send @Mohammad Jawish a frimware with v 60.10 (triple-a brand I presume?) and send me one with v 71.03 (renovo brand)

do you @Coulomb think this is possible? or the components of the inverter are always the same? I have no expertise in these things
but they also sent Mohammad Jawish a copy of v 84.00 which would mean the first number is not a number for a certain brand or at least that the frimwares are interchangable between brands.

Groan. Yet another overlapping firmware series. But thanks for posting the firmwares. I have not seen any 71.xx for this model, and 57.16 seems more recent than version 57.11 that I have.

The first TWO digits are supposed to be unique to a model, but they have basically run out of combinations of two digits, and/or are too lazy to check if the combination is used before.

Unfortunately, 71.xx is used by several other models: Axpert MKS III (not the same as a VM III), Axpert MKS II (with xx large, > 70), and Axpert King 1 (before they overflowed 71.xx and went to 72.xx). I have no idea so far what the difference is between this 71.xx and the 60.xx and 84.00 (and maybe other 84.xx).

There could be differences. Some brands (e.g. Aerox) seem to have an arrangement with Voltronic whereby they get a special display with unique icons, a special power rating (often 200 W higher than other similar models), and possibly other changes. So I would be very reluctant to mix 71.xx with anything else, at least until we know more.

Unfortunately, comparing binary firmwares is a tedious and time consuming business, and I have several other distractions at present.

84.00 seems to be a one-off; I've not heard of other 84.xx. But there could be more. I haven't had the time to compare 84.00 with any of the 60.xx yet either.

I'm trying to update using usb-a to micro-usb cable becuse I dont have rs-232 to usb cable
but each time I connect the cable windows says it cant recognize the device, also watchpower cant detect the inverter
in the guide voltronic sent me. it stated that I can update using micro usb

Edit: I think I won't be able to update mcu using USB method even if it worked for dsp

I'll use an old laptop with rs-232 for the update

Ah, my bad. I didn't realise that the VM III and VM IV models have a USB capable reflash tool. I should update the firmware upload instructions. 

Are you selecting USB in the interface drop-down box? Though it's strange that Watchpower can't see the inverter either. That suggests something wrong with the USB cable.

If you have the correct On-The-Go (OTG) cable, you could try reflashing via a USB stick, copying the hex file to the root folder of a USB stick. I think that the file will have to be renamed to vm3.hex. Instructions are in the user manual, o the AEVA firmware upload instructions. But the USB stick method will definitely not work for display (MCU) reflashes, as the library code for the USB file system is in the display firmware.

23 hours ago, Eddie1 said:

I'm not sure. It might work, as there is no "file system" involved, and the display hardware I believe converts high speed USB packets into a low-speed serial data stream, just like RS-232.

Wow, that must be an old laptop. The 9-pin RS-232 connector is huge by today's standards, so I think that laptops, with their limited space, were  the first to drop RS-232 ports. That should work.

860.96: float bug only

I've flashed this firmware with the hopes to see my batteries finally balanced
But it just stops charging at float voltage still (please check attached image)
This happens on solar-only charging, with grid it goes to float (at least it did on other firmwares, can't check right now)
I have still plenty of solar available at the last point
Was I mistaken and the fix is not for this?
Thanks!

I see the battery voltage going  to 55.2 V, occasionally to 55.3 V.

* What is your CV (bulk/absorb) voltage? That sounds like a CV voltage to me,  but it depends on your battery and the  CV voltage setting.

This patched firmware has a  new algorithm that has not been proven yet. It's only 10 or so lines of code, so I figured I'd be unlikely to  get it wrong, but it's certainly possible.

The voltage criterion is now that the battery voltage must strictly exceed (not merely equal)  the CV voltage  less 0.3 V (for  48 V models; 0.2 V for  24 V models). In other words, it must be at most 0.2 V below the CV  voltage setting for  30  seconds with no  exceptions to  get to the float stage. Does that sound reasonable?

It's possible that with your battery rarely seeing the  CV voltage, they might take longer than normal  to reach float for a few cycles.

* What chemistry is your battery?

Maybe mine is the same.

Never goes to CV at 56.2V. Always stops at float at 54.9V.

In the morning  diode blinking (means bulk) but goes to float(stays ON) very early when battery is about 53V-53.6V or so.No matter there is on grid or PV. No logick here claudy or sunny always the same. Mybe it is hardware fault . I checked 5 firmwares and nothing changes.

 

So CV level  practically  not exist in my inverter .

your inverter has touch buttons and it's OK to update MCU FW from 57.xx to 25.xx (Do it at your own risk!)

My MCU HAS NOT touch buttons and the buttons stop working after update from 57.08 to 25.08, I don't think that factory rest will solve this problem. I'm trying to get MCU FW 57.10 to test it.

Did you end up solving your problem?

Have you succeeded in obtaining a 57.xx MCU firmware?

Did you ever try a factory reset after your first upgrade? Talking software, in general it is highly recommended even in routine upgrades to do a settings reset when there is a big version difference.

UPDATE: I just obtained a 57.xx MCU firmware, please check my following posts.

is there a way for a true bypass? I'd like for it to just bypass grid at night and shut off since I don't have batteries. 

Thank you for the additional information. Did you have the exact same charging behavior before you re-flashed your inverter for the very first time? I still think this is all happening by design, which may or may not be disabled in stock firmware, there is nothing for sure in this regard!
