Victron Connect blocked access to SmartSolar settings

With Victron Connect v 5.41, something very surprising happened yesterday. When I tried to see what my MMPTs were doing, I noticed a warning marker over the settings icon and when I clicked, I was told that my access to either view or edit my MMPT settings was blocked - unless I performed a firmware update. Is this correct - I haven't seen that before with VC.

MK2 Cant find com port (Quattro)

Downloaded yesterday the software package for Quattros.

( VE Configuration tools for VE.Bus Products )

Have a MK2 interface which I have used before.
Ve.Bus system configurator cant detect the com port.
First tried it on a three phase system and could not connect, then went to our boat where is a single phase system and same.
The ethernet cable is OK, the MK2 interface is ok and detected by windows.

Remote VE.Bus firmware updates

Hello all! On April 6th we've released Venus OS version v2.65. It adds a feature which many distributors and installers have been looking forward to for a long time: being able to remotely update the firmware of our Inverter/chargers as well as Inverters: Multis, Quattros, MultiPlusses, and so forth.

The purpose of this topic is to have one - easy to update - place to confirm the latest status, issues and improvements.

Currently, the feature is still in beta, and clearly marked as such on the VRM Portal.

Current status:

UPDATED 2021-04-19: this feature has been used a lot, and without issues. Its no longer in beta; its now a normally available feature.

General advise:
Fully study the manual (link below) from the beginning to the end before you start. The inverter/charger is the heart of a Victron Energy system, during the update AC will be switched off for a while, as such comms. might be lost as well, and so forth and forth: its a super powerful feature but does require more care than -for example- firmware updating a Solar Charger.

Where to report issues:
Preferably by posting a question here below. We're monitoring this thread.


Updates 2021-04-19:

  • Feature is no longer in beta.

Updates 2021-04-13:

  • Venus OS v2.66 released officially. Has some minor stability improvements.

Updates 2021-04-09:

  • Small bug in the VRM portal was fixed, that (sometimes) caused the final error message to not become visible. That could for example happen when uploading a settings template file without first merging the file in VE.Bus System Configurator

Updates 2021-04-07:

  • Released Venus OS v2.66~1 for testing; with some minor stability updates for Remote VE.Bus firmware updates. There is no need to use that test version to update your inverter/charger firmware.

Updates 2021-04-06:

  • Venus OS v2.65 released officially

Updates 2021-04-01:

  • A new VE.Bus System Configurator tool version was released, adding the Merge function. See FAQ Q3 in above linked manual for what that is and what its for. And also this new version has a bugfix, to fix a crash when processing the settings template from a system with Quattros.
  • Documentation and in-app texts are being updated wrt setting the charge current to zero after the update, since it works slightly different than was documented. Not the charge current is set to zero, but the charge voltages are set to the nominal battery voltage. Ie. both float and absorption are set to 12V for a 12V system, to 24V for a 24V system and 48V for a 48V system. We’re doing this instead of setting the current since this works better. Also, in a DVCC system, its good to know that these settings will be overruled by the managed battery; and thus the system will be charging, even though the settings havent been restored yet. Which is fine: there is no risk of battery being overcharged when the battery BMS is in charge via DVCC.
  • The mechanism works stable. No known issue.
  • The release of Venus OS v2.65, the version adding this new firmware update feature, has been delayed to after the Easter weekend.

VRM email send to the administrator

Hello everyone,

I am trying to set up VRM, when adding my raspberry PI it is sending an email to the administrator, i created a new account for VRM and afterwards i created a new installation. I tried to add my raspberry PI (running Venus) to which i have connected my Multiplus 2 and my smart solar charger.
I am not sure why i am not receiving the email to add my products to the VRM.

I purchased my raspberry PI, Smart solar charger and the Multiplus 2 second hand, i do not know from what dealer the products have been purchased, contacting the previous owner did not result in a solution unfortunately.

Is there anyway to reset the administrator or another way to add my products to VRM?

Thank you and regards

Updating BMV history

There is a similar question posted (, but my question is a little different.

I don't want to recover any history, but just want to update the history with specific settings (value for Charge Cycles and Total AH Drawn specifically). I have changed the BMV fitted to the battery bank and would like to be able to transfer these values over to keep the usage accurate.

Is there any way to manually change these entries? (I want to update a BMV-700. I can access via Cerbo as well as display itself)

250/100 Tr Smart measuring 6 degrees too much


I installed an external temp sensor to cool the controller through fans in case it reaches 40°C.

Therefore I noticed that the internal temp sensor always shows 6° too much, no matter if it's day or night.

Yes, I double checked the external sensor electronics with another temp meter - they show the same...

Is there any way to recalibrate the sensor of the controller to get accurate measurements?

Victron 1200va can power electric kettle?

Can the 1200VA inverter power an electric kettle? The kettle is 1500 watts and it takes up to 6 min to boil water.

How about a 1200 watt griddle? It would be used for 10 min.

or a 1500 watt toaster oven? Cook time usually 12 min.

Model selection needed - Also Input Voltage 120V versus 230V. Help please.

In my RV, I currently have 12V battery and 120V "shorepower". My generator is Onan 10KV "Quiet Diesel", configured to output 120V.
The inverter for this system is junk. It does not "power share" and it's constantly breaking down.
I am also considering a new airconditioning system that requires 240V (US Standard).

So, there are a couple of background situations.
1) I can easily reconfigure my generator to 240V output (240V on two 120V output "legs"). My shore power cord and transfer switch are already configured to handle 240V but the actual feed into my current inverter-charger is single-leg 120V.
2) I will need to install new 240V wiring to the new airconditioning system from a new 240/230V interter charger. No problem.
3) I have approx. 700 Amp/hr of battery capacity (AGM, 12V). This battery bank would be easily reconfigured to 24V by recabling pairs in series. Again, no problem.

My technical issue : Frequently, I find that I'm limited to 120V input on the road. This can be 15Amp/120v (ordinary household current outlet) or 30Amp/120V ("TT" RV connector). I have 240V service at my home shop/garage and many RV parks have 240V outlets, but not all.
So, a basic question, Does Victron make an RV-suitable unit with about 4KW, 240V output that will accept either 120V or 240V shorepower/generator input? If so, which Victron model will do this?

Assuming the answer is no, what's the best arrangement?
Using a 120V - 240V transformer with a 240V inverter charger (with 240V input from the generator) and running a normal 240V house system from there? With load-balanced split legs for house 120V circuits and 240V to the airconditioning system.
Or use a 120V inverter charger, continue to use 120V from the shore power and generator, with a 120V - 240V transformer fed from the inverter-charger output to power the airconditioner system?
(All the above considers the battery bank configured for 24V). Which Victron model inverter would be best?

Thank you. I look forward to converting to Victron for my RV power needs.

Virtual switch / alarm output not working.

I have a really old victron multiplus compact 2000. I have tried to get the alarm output to drive a relay that will start a generator. I have had no luck in ever getting the alarm output to trigger the relay. I know the most likely option is that I have done something erroneous, but I can't help thinking the output is not working. I have programmed a lot of different options to debug the issue using VEConfig. To the very least I would expect checking the "invert VS" button would make the relay switch, but no.

What if the previous owner shorted the output, would that damage it? Any way I can see if has been shorted? The connector does not sit straight, seems like someone has used significant force to fasten the wires. What is the likelihood off damage? If damage is likely, have anyone tried repairing it? I am well above average on electronics and soldering, but I still need to know what to do.

I have connected the right alarm terminal to battery GND. The right terminal is connected to on terminal on the solenoid on the relay. The second terminal on the solenoid is connected to 12V battery. The intent is that the alarm output will allow current to flow in the relay solenoid and switch the relay on. If I short the wires going into the two alarm terminals, the relay switches.

Any ideas? Please do not ask med to deliver it to a dealer. It is installed in a cabin in the mountains and the unit is really old. The motivation to dissemble it, transport it back and forth, etc, is really low. If I cannot get it to work myself, then the unit will never start the generator.

Anyone had similar issues?

Different voltages in Blue smart 30/3 outputs

Hi, I have a blue smart 30 3 outputs. if I measure the voltage of the 2 connected outputs one says 14.6 Volts and the other says 14.1. I take the measure in the charger's output, so there's no voltage drop yet. If I use Victron connect it says it's absorption, 14,4 volts, 4 amps charging. The issue is that the 14.1 volts output is the service battery, so I think it's not fully charging.

I think 0.5 volts is a too big difference between 2 outputs in the same battery charger, could this unit be deffective? I also have another one for the genset battery and two starting batteries. The genset output in the charger is 0.4 volts higher than in starting batteries (14.6 vs 14.2). The charger is also not giving full charge when this happens, just a few amps, so I suspect the mosfet in the output could be wrong in both units. The higer voltage is always in the same connector in both chargers.

MPPT invalid history

I have a similar query to the original question “MPPT 75/10 INVALID HISTORY”

posted on JUly 10.

I can understand the original explanation about the MPPT only distinguishing a day by the commencement & finish of solar charging, but can’t understand why it would vary the previous days readings each day. If it can’t distinguish a day/night cycle in the first case, how can it cycle through each day in the 28 cycle. I’m a little confused about the latter.

BMV & SmartSolar Streetlight to warm battery box

Hi, I have a 190ah LFP battery going in to an ammo can which will be in my truck bed. I'd like to heat the box using small ~25w heat strip(s) when the battery is too cold to charge, but only if it was going to charge in the first place.

What I mean by that, is that if it's the middle of the night and below freezing, don't bother because there's no sun to charge with anyway. Similarly, if I have a foot of snow on the panels and it's freezing outside, don't bother because the panels might not even produce enough voltage to initiate a charge cycle.

I was thinking some combination of the street light function, load ouput, and BMV low temperature relay setting could accomplish this. Likely easily with the ability to invert the streetlight functionality but I do not think that's possible from my research. Maybe some NC relay that the streetlight triggers when it'd normally be operating an actual streetlight (night?)

Any ideas appreciated!
