VE.Can

Dear Community,

I would like to request your help regarding setup of a Skylla IP65 12/70 1+1 connected on VE.CAN to a intelligent BMS.

A REC-ABMS is issuing CVL, CCL and DCL data (respectively Charge Voltage Limit, Charge Current Limit and Discharge Current Limit). Data appears correctly on a GX display.
The Skylla is also connected to the GX display and data appears ax expected on the same GX display.

I would like to configure the Skylla so it follows CVL and CCL values. I have enabled the BMS Present feature (#31) but this lead to the following error after apporximately 10s : "error 67 : BMS connection lost".

I would be very grateful if someone could help suggesting the setup necessary to get the Skylla to honour the CVL and CCL data.

Best regards,

I had many High Battery Voltage Alarms after install today of the first 250/100 VE.Can

Good news is we now have another 3,920w Solar array working on the boat!

But the alarms were triggered by the MPPT relay output set at 28.00v and off at 27.90v. (I was hoping to use it to turn on a battery fan during charging)

Every time the MPPT hit 28v the alarm was triggered and cleared below 27.9v, but I didn't expect an alarm warning from setting the relay. (Simple FLA battery bank 28.90v Abs, so alarms were below Abs voltage)

Turning off the relay didn't stop the alarms, but setting the Voltage trigger points of the relay higher have at least stopped alarms for now.

Setting a disable alarm rule in VRM also didn't stop the alarms.

Smartsolar MPPT VE.Can 250/100 v3.04

CCGX V2.63

These Settings stopped the alarms (Setting the relay to be triggered at a higher voltage than battery voltage):

Hi all.

Im looking into getting the curent voltage or any momentary information on the VE.Can.

I already looked into the VE.Can registers public pdf and looked through a lot of questions here. I did not find annything on this.

My settup consist of a Lynx Shunt VE.Can a Venus GX and a Smart Shunt (I am just testing at the moment).

So far i am able to reach the registers for the historic values however it would make my work a lot easier to get values such as momentary Voltage, current and consumed Ah since i am looking into integrating these Values into another system via a Can Bus connection.

Are there any registers that would give me these informations?

Thanks

Hello Community,

in december 2019 a great feature was added to the firmware 1.47 of the VE.direct MPPT chargers:

tail current mechanism improved: it can now use the real battery current. The current can be received via VE.Smart Networking (Bluetooth) as well as from a GX Device

This is a useful feature I'm using in most installations since it has been released. A week ago I tried to do the same with a VE.Can SmartSolar and unfortunately it doesn't seem to work at all.

The system consists of a CCGX, BMV700, Multiplus 5000 and VE.Can 250/100 SmartSolar. Other devices have been removed to keep things more simple.

There is no ESS/HUB assistant installed and therefore no active external control of the charger. Also no bluetooth smart network has been created and the firmware is up to date on all products. In the system the BMV is set as the default battery monitor to use and SOC syncs well with the multiplus. DVCC and SCS are enabled and SCS status is active. In the carger the absorption time is set to a fixed time with a tail current of 10A. If the current value falls below that value for more than one minute the charger should end absorption stage earlier and pass over to float. But it doesn't. Nevertheless DVCC is working with voltage, temperature and even current (tried a limit on the system). It seems the charger just has no use for the value "battery current" sent from the BMV and uses it's own current value instead to end absorption.

I have asked dealers, distributors and victron support, but all of them told me the charger would be able to do this without testing it. So I'd really appreciate if someone with a new CAN system (the old chargers can't) could test this. Of course a load must be switched on to have different current values between charger and BMV. I just want to know if this feature is working or has not been implemented yet and victron doesn't know about itself. If it works probably someone finds a mistake in my settings? I would prefer I made a mistake.

Thank you very much!

I have two BMV-700s hooked up via VE.direct 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.

I have two SmartShunts connected to the Cerbo with VE.Direct.
As far as I understand the Cerbo puts the information on the VE.CAN.

Is there a table with the available VREG's? Is it similar to the Lynx Ion?

Which VREG's are sent periodically, which are send on change and which need to be requested?

Hello!

We are installing lithium batteries with their own BMS working at 250 kbits/s using EasySolar-II GX and Multiplus-II GX units. It seems the Multiplus-II GX units do not have the 250 kbit/s baud rate option, as do all the other GX units.

[image]

Is there a way to get the Multiplus-II-GX to work at 250 kbit/s? Changing firmware perhaps?

The batteries have been tested with a Color Control GX and work fine. But it is not working with the Multiplus-II GX.

Any help is appreciated. We have 450 units of those standing by...

Regards,

Jordi Faxedas

I'm trying to figure out how to take advantage of the tank monitoring capabilities in the CCGX. I know for resistive sending units I need the VE.Can resistive tank sender adapter... My only problem is I have three tanks (Fresh, grey, and black) and these adapters cost $400 each!!! I would end up spending more than twice as much on these "adapters" as I have invested in the CCGX itself.

So I started looking at options. For RV holding tank monitoring: SeeLevel II is pretty much considered the standard for high end monitoring. When i was looking at their product offerings I noticed they have sending units that support "RV-C" which is a CAN Bus based protocol. Since the VE.Can adapter simply converts the resistance it gets from the tank into CAN Bus messages... If the SeeLevel II sends CAN Bus messages to begin with then it *should* be fairly straightforward to just connect these to my existing VE Can bus (I already have a CAN bus between the CCGX and my Orion Lithum BMS system)

That's assuming that the RV-C messages sent by the SeeLevel II are compatible with whatever message format the VE.Can adapter sends. I'm hoping someone from Victron can help me out.

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?

I have a client with a 150/85 Ve.Can MPPT and 1260w of panels but he wants to add 840w more. Both of which charge the same battery bank. The current 150/85 is connected to a Color Control GX via a Ve.Direct cable. If I add another Ve.Can MPPT and use a RJ45 to connect them in parallel will the Ve.Direct to the GX display the information for both MPPTs?

I know that a RJ45 would of done this to the GX per the manual, but I can't find anywhere if the Ve.Direct will work the same.

Or should I just use the Smart Networking to put the MPPTs in parallel? And if I do that will the Ve.Direct send the info to the GX for both controllers?

The two MPPTs will be on different arrays and have thier own wires. It's just a pain to run another Ve.Direct or RJ45 to the GX, plus it will save the customer on labor cost.

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

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

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

Good day. I have a CCGX with a VE.Direct MPPT, VE.CAN Freedom battery, VE.BUS Multi and a VE.BUS Digital Control. I want to monitor a tank as well. Will the VE.CAN Resistive Tank Sender Adaptor be able to communicate via VE.CAN as well. The battery bank is using the VE.CAN port

Hi !

The documatation of the CAN registers "VE.Can registers" is mentioning in the examples node numbers.

From the document:

Victron Request (0x0001) for Firmware Version (0x0102) of node at address 0x40 from
address 0x20:
7.0.0.EF.40.20 0x66 0x99 0x01 0x00 0x02 0x01 0xFF 0xFF

Where can I find an overview which Victron product is using which node number?

Thanks in advance!

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

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,

[image]

[image]

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

I'm looking for experience around controlling Victron inverters over CANBUS. I was told by Orion that their Jr BMS could shut down discharge to protect my battery over CAN, but would likely need some sort of gateway.

I am planning a system around the Cerbo GX that includes:

• Victron Lithium batteries
• VE.Bus BMS
• Victron SmartShunt

I would like to interface with the Wakespeed WS500 alternator regulator that accepts VE.Can data to adjust charge rates/voltages.

Does the CerboGX VE.Can port output battery parameters (charge voltage, current limitation, battery current, etc)? Or does the CerboGX only listen on the VE.Can ports?

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.

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 https://www.victronenergy.com/solar-charge-controllers 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.

I have read the page showing lithium battery compatibility at https://www.victronenergy.com/live/battery_compatibility:start, 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!

Cheers

Hello. I have a SmartSolar 150/70 MPPT Tr ve.can connected via CAN interface with a REC BMS and Wakespeed WS500. Is it possible to configure the MPPT to not send out charging commands and simply take direction from the BMS (it seems to disrupt the WS500)? If so, how does one do this? The VE.CAN setting don't seem to be configurable from the bluetooth app and I can't quite confirm what the right software and adapter is to do this from a PC.

Thanks

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 VE.direct 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.

[image]

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.

Hi anybody else with problems with MPPTs connected throug LAN?

Often my cerbo doesnt rekognize them and reports missing devices, today it shows one of the MPPTS (OST) corrupted as two devices named 0 8 WST (-> See screenshot)
I was wondering why we are producing so much energy :-)

[image]

Bouvht the latest Smart solar MPPT because it has VE.CAN,now I read that remote configuration is not available yet using VE.CAN. Should I wait or buy VE. Direct cables to have the option?

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.

[image]

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?

Many Thanks

Good day,

I have a SmartSolar MPPT 250/100 Tr and I need to add another MPPT to my configuration.

I like the SmartSolar MPPT 250/100 Tr VE.CAN and its ability to synchronise charging across multiple MPPTs.

Can I use VE.Direct to VE.CAN interface cable to connect my old and new MPPT?

Equipment:

MPPT 150/100-Tr VE.Can connected to PC using VE.Direct port & Victron serial adapter cable.

Scenario:

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.

[image]

Question:

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

Notes:

• 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.

Thanks kindly,

Allen

Have anyone tried to use a Can air or wireless can bridge on the VE.Can net?

Like: https://esd.eu/en/products/can-air2

I have a Lynx Shunt VE.Can (https://www.victronenergy.com/battery-monitors/lynx-shunt-ve-can) and I would like to connect some non-Victron kit to it to determine power in/out.

The BMV-700 appears to be a 500A / 50mV.

What values should I use for the 1000A Lynx Shunt VE.Can?
