Multiplus-2 does not appear on victron connect

Hi all,

I am trying to update the firmware of my easy solar-2 GX 48|3000|35

I am using CAT5e (connected to one of the VE.bus ports) and Mk3 to USB to connect on my windows computer. When I open my victron connect app on windows laptop, on the device list page, in LOCAL section all I can see is EasySolar-2 and not multiplus 2.

What do I need to do for it to appear on victron connect?

I also looked online and found old method of firmware update using veflash. I can not find where I can download veflash anymore?

Please help

Phoenix Inverter VE.Direct 24/1200 alternately flashing red and green - needs a firmware file

I have a Phoenix 24/1200 inverter with alternately flashing red and green leds, which apparently means a calibration or firmware error.

To try to fix it, it was recommended to re-flash the firmware, but VictronConnect says it is up-to-date with V1.22, and doesn’t allow re-flashing except with a manually downloaded file.

Does anyone know where to find the correct firmware file?

On Victron-Professional there is a whole list of V1.21 files - none of them are accepted by VictronConnect (they all give error D90, "firmware is not for this product").

With an older version of VictronConnect the Phoenix 24/1200 inverter identifies itself as unsupported but it gives the product ID as A2F2 so if I correctly understand the naming conventions, it would need a firmware file called “phoenix_inverter_A2F2_v01.21.dup” which is not listed under “Phoenix Inverter VE.Direct”.

This inverter was just bought and has had this problem since the very beginning, unfortunately it came from a dealer in Slovakia whereas I am in France, so I am hoping to be able to fix it without having to pay the rather expensive postage for returning it, since apparently Victron does not handle any warranty issues directly, i.e., only be going through the dealer who sold the device …

Many thanks for any insights!

24v Phoenix 1200w - Alternating flashing LEDs - no AC output


I've had my 24v Phoenix 1200w (120v) inverter running solidly for a little less than a year now. Firmware is 1.21.

Switched it on this afternoon and there was no AC output. The red and the green LEDs flash in an alternating fashion every half a second or so. Toolkit shows this as "Calibration or Parameter Error".

I've tried checking and resaving all the parameters (all were fine) and then refreshing the firmware with A27A_01.21 but no luck.

Does anyone have insight into why this suddenly happened or what can be done to rectify this ?

Many thanks in advance,

Cerbo GX Remote Console connection issues after FW update to 2.62 (also in 2.63 and 2.65)

Yesterday I updated my Cerbo GX from firmware 2.60 to the newly released 2.62.

Cerbo GX is connected to my Internet router using WiFi.

Several times already (first time it happened yesterday, while looking into the Cerbo GX settings after the FW update) Cerbo GX was not accessible using Remote Console via LAN for several minutes.

After a few minutes I can access it again (without doing anything to fix the issue).

When this happens, on VRM there are no updates for a few minutes (VRM portal log interval is set at 1 minute).

Not sure if this is a WiFi issue (haven't got a chance to try it with a LAN cable since updating the FW) or if Cerbo GX freezes for a few minutes and that is why I can't access it with Remote Console over LAN.

The WiFi and Bluetooth LEDs are blinking normally even when this happens (or I did not catch them in time).

Yesterday, after the first time it did this, I did a Cerbo GX reboot (from Remote Console menus), but again it had the issue today: once when I tried Remote Console from a phone and second time when I tried from a PC (both devices were in the same LAN with Cerbo GX).

I never observed this problem with 2.60 firmware.

Anyone else has this issue after updating the firmware to 2.62?

Hello everybody, just registered for my first question.

im super new to Victron Components but i i have read a lot the last couple of month.

I would like to know if it is possible to update my Multi Plus with SN 19xx125, to a higher Version which work with the Cerbo Gx an allows me to limit the charge current via Victron Connect iOS or Mac.

The Cerbo Manuel tells me its possible with Firmware 422 to have access ti DVCC, but maybe wit Firmware 2xx it might be possible to show the Multi at least in the Connect App or VRM Network?

So far with my Firmware 125 of Multi, i have no access at all.

Before i try updating, i just wanna make sure, not to do stupid and unnecessary things.

Thanks for your help.

Smart Solar MPPT 250/85 cycling PV to 0 after 1.54 upgrade


This system was disconnected for a few months. It is a marine application. Returning to the boat we powered up the solar controller and everything looked normal looking at the Color Controller. I logged onto VictronConnect to the solar controller via Bluetoot. As seems to be normal in this situation, the app prompted an update to the controller from 1.2x. It did 2 updates ending at 1.54 before allowing continuation to the data.

After the updates, I am seeing cycling of the PV input from a normal 450w to 0. It is doing this several times a minute. All was steady and consistent before logging on and updating.

Is this a known issue? Anyone have some advice on what the cause might be? Is it possible to roll back the update?

Nach Update auf V1.50; Warum lädt der MPPT 75/15 Laderegler nur noch in Erhaltungsspannung (Bulk) ?

Hallo, wir haben einen Smart Solar MPPT 75/15 an einem 110 Watt Solar Panel und einer 225 Amp/h Batterie installiert.

Vor dem Software Update auf V.1.50 hat das System toll funktioniert.

Bulk und Float alles ok. Siehe bitte Foto.

Nach dem Update auf V1.50 kennt das System nur noch Bulk - Ladung.

In den Tagen vor und nach dem Software Update waren keine Stromverbraucher aktiv. Auch sonst wurde nichts am System verändert.

Wir haben nun seit 3 Tagen Verbraucher hinzugeschaltet. Das System lädt weiterhin nur in Erhaltungsladung - Bulk weiter. Die Sonneneinstrahlung ist in den Tagen vergleichbar.

Warum lädt der MPPT 75/15 nur noch in Erhaltungsspannung (Bulk) ?

Gibt es ein neues Softwareupdate? Oder kann man auf die alte Software Version zurück wechseln?

Vielen Dank schon einmal im voraus für die Informationen.

Pheonix Inverter 24/3000

Hello, Im having problems with my Pheonix 24/3000 inverter. After buying it second hand, I have never got it to work. First it simply did nothing when i flicked the switch, now the green light ontop is flashing but there is still no output power.

Both occasions I checked the voltage at the inverter terminals and beyond the fuse. It showed 25.5v when the power switch was off and when it was on. So I dont think there is a bad connection. It is however quite cold here in Sweden and it has been in a room the has been below 0 degrees celcius on both attemps. The first attempt was maybe at -4c when the inverter showed no light and -10c on the attempt when the light started flashing.

Could it just be the cold?

The batteries are gel batteries that stay topped up so I think they can handle the cold.


I had a hope that doing a software update might make it work again but VictronConnect cannot find the device when plugged in. It is connected to the laptop with an RJ45 cable through a USB adapter.

Could it be the adapter that doesnt allow the connection?

There are 2 RJ45 ports in the inverter. Ive tried both of them.


Thanks folks! Any advice is much appreciated.

Updating Smartsolar 150/100 to firmware 1.54 ?

Hello everyone, I am asking myself if I will update the smartsolar MPPT 150/100 MC4 from firmware 1.50 to 1.54. My concerns are related to a possible crash and also issues commented by other users with FW. 1.54.

I am not currently in my residence country and locked here up to May 2021. My setup is currently working fine, I just updated the Cerbo GX to 2.62, and the BMV-700 to 3.11, but the key is the MPPT which produces all the power for the battery bank.

Being far away, I do have some doubts about the stability of the firmware, and the risk of crashing the MPPT during the firmware update through the Cerbo GX.

Any advices from Victron Staff would be appreciated.

Thanks for your time and help.

Quattro Firmware issues

Good evening all,

I have had a very interesting experience trying to update a 5kVA Quattro.

The unit is running v430, hence the need to update. (quattro is standing idle and has very low load on it)

What happened:

- Downloaded and saved config using VEconfig using MK3 cable (verified it workes)

- Got the quattro ready for firmware update, unplugged venus and turned it off as indicated.

- Plugged MK3 cable into quattro and turned it on.

- The quattro did not turn on and the temperature LED was now on.

- I proceeded to try connect and got a failed message....

- I toggled the on/off switch, sometimes the temperature LED would go on, sometimes not... and VEflash was not happy.

-I then removed the MK3 connection and tried to turn the unit on... No response.

-Now getting worried (as you can understand)

- pluged in the venus, and bam the unit turns on.

I tried this multiple times and nothing seems to repeat (except the fact that it wont update)

At one stage a whole bunch of LED's started flashing, but nothing consistent which I could record.

I have yet to try and update using VictronConnect, but besides that, does anyone see what I am doing wrong?

regards Ewald

#10 Alarm system time sync error , #1 device switched off random reboots

For last couple of months my system ( 3 x 5 KVA Quattors in 3 phase with BYD 10 KWH) randomly resets ( all the quartos go offline and come back on)

#10 Alarm system time sync error, #1 device switched off commonly seen.

Initially, I Suspected network cabling so replaced with CAT 7 high-quality cables and cleaned the network sockets with contact cleaning fluid

Also, checked if all DC connections are tight ( they are )

There seems to be no pattern to these switch offs ( observed at 2 am in the night and also during afternoon or evenings ) -

The system works fine for a couple of weeks and in one day I could face one or more restarts with associated error logs

All firmwares are the latest except Quatro which are on V430 ( latest is 464 i believe)


1- Is there a detailed log somewhere indicating which unit is causing the shutdown

2. Should I upgrade quattro firmsware to rule out any other issues

3. Is this the issue of any external EMF affecting the network cabling ( they run parallel to the power cables - not in my opinion as CAT 7 are each pair individually shielded )

Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the quality of the twists to protect from EMI. This involves a tight twist and carefully controlled design. Cables with individual shielding per pair such as category 7 rely mostly on the shield and therefore have pairs with longer twists.

windows serial bluesolar firmware update fails
First of all, I know I should be using a victron usb to serial lead, but don't have one and no real way to get one any time soon. If it were possible I'd spend the money in an instant!

So trying to get a windows 10 laptop to talk to a Bluesolar MPPT 75/10. To get from serial to USB it's going through an arduino mega which has several serial ports running at 5v. Seems to be talking OK, I also have a smartsolar which was already had a firmware update over bluetooth and seems to work OK with the same serial/usb setup, settings can be changed.

With both RX & TX are connect the victron app boots up and finds the device, click on the icon and it flashes a page then goes into a firmware update pageshowing =>

current version V1.30

new version v1.54

Click on update and it gets as far as 5% then stalls, stays at 5% for little while then says =>

Update failed

result : d255 inknown error

Both LEDs on the device flash alternately.

That's it, every time.

From the arduino serial monitor the bluesolar is send this >

Firmware updates: Never change a running system - except when you should

Yesterday I experienced once more a "weird behavior" of my to-be-experimented-upon-Quattro (2658, firmware 408): after modifying the battery voltage threshold for inverter shutdown from ridiculously low 37-something to 41-something and the subsequent reset of the device, the Quattro stubbornly refused to even look at (the present) mains.

I mean like unexplained behavior - to me.

As over the years I developed a somewhat close relationship to this specific Quattro, I might even say to have some kind of intuition about its feelings and desires. So I intuitively switched it to "charger only" mode" (1st blackout). Et voila! It recognized main and started charging the battery.

I then switched it back to on (2nd blackout) - Et voila again! Now it saw mains and started to behave as expected. Maybe I will start calling her(?) "my little diva".

Now: I know Victron is a little reluctant with people updating their firmwares, although it seems not as rigorous anymore as it was in the past:


which I find a good development. It makes the user feel being taken more seriously. While I agree with the general sentiment that firmware upgrades shouldn't be done lightly or as some trial&error a.k.a. "cargo culting", I think that giving users even more information at hand so they could make an informed decision whether to upgrade or not would be a good idea.

There is a quite nice "changelog firmware.docx" file under and I am not aware of it being available publicly. If it isn't - here's the thing: It may seem relevant only to those who actually do have access to the .vff files, but in fact this changelog file should be available to everyone.

If read carefully, one has a so-called "diff" of the features of a current firmware and the present firmware in one place that should ease the decision "Yes I do/do not need a new firmware." It also - if you are able to read "between the lines" gives proof that it is NOT desireable (as Victron points out) to really keep your firmware updated to the newest version.

I read the changelog today, to see if something in there could be applied to my "ignoring mains" situation. And there it is:


  • Bug fix. Some models exhibit occasionally rejection of the grid

At least I believe that is relevant to my situation. But wait, it doesn't end there. While reading through the changelog (since 408) thoroughly, I encountered

xxxx428: Bugfix "parallel and 3-phase not working because of false E11" (This error was introduced in version xx25425)

And this is the very reason one shouldn't simply update to latest. because if you were operating a parallel or 3-p system and updated to 425 "just because", you might have experienced a bad time until 428.

So with all that said, it would seem I need 456. Available versions are 433, 459 and 465. 433 too low obviously, 459 would be ok, changelog between 459 and 465 shows a nice feature "display the remaining waiting time before connecting to grid and also to display the cause of a grid rejection" on the other hand it also shows "A lot of under the hood changes." while I'm sure the latter is good for future enhancements, it also tends to introduce new errors. And indeed, 461/462/463 seem a little bit on the stabilization side. As there also are no critical bugfixes between 459 and 465, the conservative choice is on.

So 459 it is! For me.

Firmware updates - File sizes? Time needed?

Hello wise friends.

Next week I will be standing in a new yacht on the other side of the planet, programming a Victron lithium battery system I have never seen, with software I have never used, while a boatyard full of onlookers and their hired assistants wait for my go ahead to launch the vessel. I need some answers on what to expect.

Re firmware updates

- do any of the sub-systems listed below have the potential not to work unless their firmware is updated first? I will be connecting to them with an internet capable iPhone or iPad and VictronConnect, a process that might detect firmware version anomalies.

- for any of the sub-systems listed, is it recommended to check for the latest firmware and install it if available?

- for any of the sub-systems listed, is it recommended not to update the firmware unless performance problems have been detected? I keep seeing mixed messages on this - always check for the latest firmware vs never update a system that is working.

- importantly, what are the firmware file sizes and download/installation times? Anything to be wary of? I will not have had the time or the opportunity during a pandemic lockdown to buy a local SIM card, so will be downloading via international roaming, with limited data availability, though with good 4G speeds I expect. I can't afford to be trapped by a spinning 'Updating' wheel, over and over again.

The gear list is:

12.8V 300Ah Smart Lithium Batteries

Cerbo GX

GX Touch 50 display

Smart Shunt 500

MultiPlus 12/3000/120-50

Smart BMS CL 12-100

Smart Battery Protect 220 (load protection)

Smart Battery Protect 100 (charge protection)

Smart Solar Charge Controller MPPT 100/50
