VRM Remote firmware update freezes at status 'Querying VE.Direct devices...'

VRM firmware update freezes at status 'Querying VE.Direct devices...' after succesful update of the first SmartSolar Charger VE.Can 150/70 from v1.06 to v3.02.

There is no error message generated except the warning 'Installation too busy, realtime date link disabled'.

The SmartSolar Chargers VE.Can 150/70 are connected with VE.Direct to Venus GX v2.60

Any suggestions to fix this to update the leftover chargers without using local Bluetooth and without the need of travelling to the site in Corona times?

Pylontech US2000B and VE.Can MPPT

I currently have 5KVA Multiplus with a 150/70 VE.Can MPPT charge controller using ESS with CCGX.

My current VRLA batteries are in need of replacement and was looking at replacing them with Pylontech US2000B or US3000 batteries. According to this article its not possible

Is this still that case as it its not possible at all or are there limitations?

How to display battery voltage from two BMV-700s on Raymarine Axiom 7?

I have two BMV-700s hooked up via to a Cerbo GX. I have the Cerbo GX integrated with a Raymarine Axiom 7 via the network port AND VE.can. I can access both BMV-700s via the Victron App on the Axiom. I can get only one of the BMV-700s to populate the Battery 1 data box on the Axiom. I can't get either BMV-700 to populate the Battery 2 data box on the Axiom. I read the instructions and can change the data instance of each BMV-700, but I can't change the instance to 1. I can change the instance to 2,3,9, or 0, but I can't change it to 1. I used Actisence NMEA Reader and a NGT-1 to change data instances. All equipment and software has been updated to the latest rev.

VE.Bus BMS, SmartSolar MPPT Ve.Can and Can verses VE.Direct connection

I have a 2 x SmartSolar MPPT VE.Can 150/70 rev2, Smart lithium, MultiPlus, BMS, Cervo, etc, all Victron.

I have not found any clear documentation about the functionality one gets when connecting the SmartSolar MPPT via VE.Can or VE.Direct.

I connected them originally via VE.Can and no screens on the VenusOS would show if the MPPT's where working as a single pair, networked and in sync, or would get BMS Charge Disable signals from the Cerbo.

I have them connected via VE.Direct at the moment, and in the Cerbo there is now a "Networked operation" screen, under each charge controller. However BMS control is still No.

Is there any documentation or guidance that exists about the best protocol to use to connect the controllers and the benefits and features of each.

I really want to know if the BMS Charge Disconnect signal is passed through from VE.Direct to the MPPT's, can they work as a synchronised pair, can they get charge current (non ESS setup) from the Cerbo, etc.

Many Thanks

Pair of VE.Can Enabled and Connected Smart Solar MPPT

I have a Cerbo and 2 x VECan enabled Smart Solar controllers. I expected these two be working a s network pair, but they do not seem to be. They each report their own System Yield and not a combined yield for system, see attached,



Should the system yield actually be the combination of the Total from each unit? How does one tell if they are working as a synchronised network pair. I have been unable to find any detail on the web or gain access to the Cerbo itself to look at the dBus data elements to see how they are interacting with the system.

Any guidance.

Many Thanks

bluesolar 150/70 VE.Can GX recognition

We are trying to connect

3x BlueSolar MPPT 150/70 (2015) [firmware v2.05 for all three]

to a

CCGX (2015) [firmware v2.60]

The BlueSolars are daisy chained via VE.Can with a terminator on the last one.

The CCGX has a terminator on it.

The blue solars don't show up in the CCGX at all (using VE.Can).

We have a CerboGX (firmware v.2.60)which we used to update the firmware on all three Blue Solars to v2.05.

We can get the Blue Solars to show up on the CerboGX through VE.Can. Both individually and together with all three showing up as a single Blue Solar charger on the CerboGX.

Curiously when the Blue Solar chargers are shown on the CerboGX, the information flashes on and off. See attached Video.

The long term goal is to connect the blue solars to the CCGX. Why the CCGX does not see the BlueSolars when the CerboGX does is beyond me.

Clarify Solar charge controller page and VE.Can

From the specs/manual it appears the reason you would want to choose a SmartSolar controller with VE.Can instead of one without is if you want multiple charge controllers to all be in perfect sync with each other as far as charging stages. Is this correct?

If so it would be really helpful if the top of the page at would mention that to make it easier for people to understand why you should choose one with that option or not. Everything else is explained at the top except for that.

Using unapproved lithium battery with Quattro, pros and cons?

I have read the page showing lithium battery compatibility at, but still don't understand why you cannot use an unapproved lithium battery?

My understanding of lithium batteries is that most have an onboard BMS, that manages individual cell voltages and charging rates. If this is the case then what benefit do you get if the GX device can communicate with the onboard BMS? Is it just so that you can read the individual cell voltages through the VRM?

Any clarity would be much appreciated!

How can I configure my VE.Can MPPT to receive messages from my BMS?

Hello. I have a SmartSolar 150/70 MPPT Tr ve.can connected via CAN interface with a REC BMS and Wakespeed WS500.

VE.Bus BMS verses smallBMS and signalling charge disconnect to MPPT controllers

As I continue to investigate the possible connection options to get my system working as I require and following on from my question about VE.Bus BMS verses smallBMS. I hope someone can help with this part of the communication flow and if any functionality is lost be using a smallBMS verses a VE.Bus BMS.

I am aware that the Cerbo is able to signal via VE.Direct or VE.Can to connected Smart MPPTs that a charge disconnect event has happened. This is confirmed in this post where Guy has stated "Yes, it works. The VE.Bus BMS will signal to the Multi on the VE.Bus, and then that will be sent to the GX device which will control the MPPTs via or VE.Can (>2019 models only) cables."

However there is nothing about the smallBMS. The above post has a link to another post where Matthijs says "Regarding connecting: the Venus GX cant retrieve data directly from the VE.Bus BMS. So, even though they are on the same network (VE.Bus); you still need an inverter/charger in that same network to make it work.". This implies to me that the MultiPlus sends the charge / load disconnect to the Cerbo and not the VE.Bus BMS itself.

While I have a VE.Bus BMS at present it is not connected to the VE.Bus and I am using a 2-wire assistant on my Multiplus. The Cerbo shows this and when the pin on the VE.Bus BMS goes high, the Cerbo state changes too yes. So I know the Cerbo is getting the information.


So the details are getting to the Cerbo. Therefore with a smallBMS or VE.Bus BMS using 2-wire assistant, will the MPPTs still get a charge disconnect via VE.Direct or VE.Can. I am unable to test at the moment as while my MPPTs are installed the Solar panels are not yet installed.

I would like to know if when using the smallBMS, the VenusOS will still signal charge disconnect to the MPPTs, and how I can tell if the signal is getting through to the MPPTs. For info I have two VE.CVan 150/70's connected via VE.Can.

Smart Solar MPPT 150/70 VE.CAN

I am about to install the above model into my system comprising a Cerbo and Smart Lithium Batteries with a VE.Bus BMS. I have been reading the manual in preparation and found the following regarding the BMS connection.


I am surprised that it suggest the VE.Bus BMS charge disconnect is connected to the L-Pin. The VE.Bus BMS will supply a high signal until a charge disconnect event occurs when the signal will drop too floating. In all other devices the VE.Bus BMS is therefore connected to the H-Pin. Even the description of the use of the L and H terminal match that in all other manual, and implies it should be connected to the H pin.

Could someone advise if this is a typo in the manual and the VE.Bus BMS should indeed be connected to the H Pin of the Smart Solar MPPT 150/70 VE.Can?

When connecting to Equipment via the VE.Direct port with Victron serial cable + PC with VictronConnect software, we are prompted to update the firmware on the device, which then fails (see attached error message: "Update failed! Result: X88 - Communication Error. Vreg Ack timeout. Please check the connection and try again". See photo for error screen.



Any idea how to fix this so we can update firmware via PC and configure settings?


  • We are able to connect with the Android App and perform the update via Bluetooth. Subsequently the connection using the VE.Direct port + PC works fine.
  • We're using the latest version of both the PC VictronConnect software as well as the Android app

If you have any ideas on how to fix this it would be appreciated, as we're expecting to be programming many of these devices and doing so via bluetooth is very time consuming.

Why is ASS030520410 VE.Direct to VE.Can interface so expensive?!

My eyes nearly popped out of my head.

I was looking for solutions to connecting more than one MPPT to a MultiPlus II GX and thought, "Could I use a VE.Can port with a VE.Direct to VE.Can adapter?".

Sure enough, there is such a thing "VE.Direct to VE.Can interface" (ASS030520410) but it is about the same price as the MPPT I want to connect about 300EUR.

Now, I have since learned that you cannot use VE.Can on the MultiPlus II GX for MPPTs but I am still interested in why the VE.Direct to VE.Can interface is so expensive?

I would like to set Charge Voltage Limit (CVL) to 56.75V, but it looks like precision is fix to just one decimal place, so I need to set it to 56.7V or 56.8V. Is there a way to have 2 decimal places (e.g. 56.75V). All settings in VE Configuration tool have precision to 2 decimal places, why CVL (and CCL as well) is different???
