Charge limit voltage (CVL) precision

I have a question about Charge Voltage Limit (CVL) when using BMS connected via CAN bus. In my system (VenusGX and Multiplus II) I'm using BMS connected via VE.Can (Batrium BMS). 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???

Kind Regards

VE.Can Regulators dropping out on CCGX

Hi Victron gurus,


Any suggestions on how to fix 2 x solar regulators connected via VE.Can to a CCGX dropping out? There is a VE.Can terminator installed at the end as well. Resetting the CCGX did not bring it back.

Skylla-IP44 cable to Cerbo GX

Hello,


Is my understanding correct that to connect Skylla-IP44 charger to Cerbo GX I need to use RJ45 cable ? It’s being referenced as VE Can, VE Bus and UTP RJ45 so I’m a bit confused.

Also, by connecting these devices I should be able to control Skylla charger through Cerbo GX remotely (on/off) ?


Thank you,

MPPT 250/100 VEcan with a Venus GX not sharing voltage & temp

We have a MPPT 250/100 VEcan connected with VEcan to a Venus GX that has Temperature sensor connected i have noticed the solar controller is not reading any temp. i have temp & volt share turned on in the venus DVCC.

So i was going to put in a smart battery sense, but the sensor manual said not to with a venus connected as it confuses the system. is this still true?

I would like to get this sorted because we are add 2 more MPPT 250/100 VEcan to the system and want the controllers to sync

VE.Can and VE.Bus???

I'm looking to expand the Victron equipment on my boat and keep seeing references to CAN and BUS....can anyone explain the difference between them?

I've seen CANBus talked about and as far as I understand the CAN is the "brains" and the Bus is the way that the data is shared. What is confusing me is the way that Victron has then separated and there are VE.Can to VE.Bus connections.

Connecting a smaller charge controller instead of a VE.CAN controller

I have a common, main DC bus bar.

I am sending 48VDC to it from various energy sources: solar, wind, hydro, a DC generator, and AC energy converted to 48VDC.

To avoid overcharging the batteries after the 48VDC bus bar, I am using VE.CAN chargers that are connected between them as a master with slaves.

One of the problems I have is that each solar panel is connected to a single VE.CAN MPPT charger. The solar panel is too small in relation to the smallest MPPT charger.

Due to shading issues I cannot connect more than one solar panel per MPPT charger.

Is there a way to connect the solar panel to a smaller MPPT charge controller without interfering with the current arrangement of not overcharging the battery or having chargers in standby?

Could a GX display or some other device help me to achieve this? Could up to six solar panels be connected through a GX display, for instance, and could this group (solar panels and device) become a slave of the master MPPT charge controller?

I thank you in advance for any assistance.

RV-C CAN Bus tank monitors

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.

Error 67 - BMS Connection Lost on Smart Solar 150/100-Tr VE.Can

I have a Smart Solar 150/100-Tr VE.Can connected by VE.Can to a MG Energy Master LV (With 2 x 200Ah HE batteries) and a Color Control GX. There is also a Multiplus 24/3000/70-16 connected by VE.Bus on the same system.


I'm having an occasional 'Error 67 - BMS connection lost' from the Smart Solar but I have unfortunately been unable to pinpoint what exactly is causing the issue. It never happens when the solar is isolated but randomly when solar is generating. It does not automatically recover unless I clear the issue by isolating our solar panels and reconnecting. Is this a known issue with Smart Solar VE.Can variants? Details are below. Many thanks!

Get AC output informations via CAN

Hi,
we are developing an aggregator including 3 Multiplus 48/5000. Our controller is able to communicate via the VE.Bus to VE.Can interface. Currently we can control the inverters and read system informations using proprietary message on the NMEA2000 but cannot get informations about the load because I could not find such VREGs. Which I do not really understand because these informations can be read in the case of other devices.

HELP NEW SmartSolar 150/70 Ve.CAN Firmware Update Issues

Hello Community.

I have just installed a new SmartSolar Ve.Can Controller. After powering it up for the first time, and connected it the VictronConnect app. It first requested a Bluetooth firmware Update, which was successful. Then when i reconnected to the app it requested for a firmware update (V1.03). The update failed at about 30%. I tried to update again, but it fails a 5% every time.

It displays this...

Current Version : none

New Version : V1.03

Ive tried unpairing and repairing, rebooting and restarting. With no success. The VictronConnect app is up to date (5.17).

My phone is Android. I have also tried using a iPhone. Also i have install a BMV 712, and a battery Smart sense, both have connected and updated with VictronConnect on my Android with no issues.

Lynx Shunt VE.Can Transmit Frequency?

Is it possible to adjust the transmit frequency of the current data (PGN 0x1F214 / 125708) from the Lynx VE.Can shunt? In our system it only seems to broadcast about once every 1.5 seconds. We're trying to feed the data via CAN to an alternator regulator and there's too much latency for the control to stabilize.

More generally, is there any documentation available for the Lynx Shunt VE.Can standalone? All I can find is the manual for the Lynx Ion w/ Shunt, which seems quite a bit different.

Multiplus II 3000 GX VE.Can Solar Charger support

Good Evening Victron Team,


The Multiplus II 3000 GX manual makes it very clear that you don’t support the use of VE.Can Solar Chargers on the VE.Can port inside the M2GX.

I have however successfully been running a 150/85 MPPT on it.

Considering that my application will not have a Can BMS in the foreseeable future, may I please request that the unsupported compatibility not be removed in future versions of either the VenusOS or M2GX Firmware?

Multiple CAN devices on Color GX

Hi,

I need to connect two CAN devices to a Color Control GX.

If I understand correctly that means I need two RJ45 terminators on the Color Control?

If the above is true I would need four CAN sockets (2 for my CAN devices, 2 for the terminators). Is it possible to plug two 'Y' RJ45 splitters into the Color Control with a terminator on one input and one of my CAN devices on the other?

So the final proposed setup would be:

Terminator--\

-- 'Y' splitter ---> Color GX CAN port 1

Can device--/

Terminator--\

-- 'Y' splitter ---> Color GX CAN port 2

Can device--/


Thanks for any help.

2.33 CCGX firmware and VE.Can devices detection

Firmware 2.32 corrected wifi loss and that was good.

Now I have the following problem for a few time and I suspect release 2.33.

I have a full "On-line" setup, where the multi is inverter only and a Skylla is charging from micro hydro OR, in summer, from generator if the solar panel+BlueSolarMPPT is not sufficient.

Before I start the generator, I switch the Skylla off until it is seen on the CCGX and the power limit can be accounted for. Then, I switch the Skylla on and everything is fine.

Now (2.33 ?) the Skylla is no longer found/seen by the CCGX when the generator starts. It's always listed as "deconnected". I have to manually reboot the CCGX for the Skylla to be listed.

If I don't reboot the CCGX, the Skylla starts at maximum current and overloads the generator.

No matter how long I wait with the Skylla powered and switched off, it never gets seen by the CCGX until rebooted.

Ve.CAN / NMEA2000 - Battery charge state

Hello,

We would like to read the state of charge (SoC) of a battery using the BMV700 and the VE.Can interface.

It seems that the correct PGN is the 0x1F212 (DC Detailed Status, page 3 of Manual-BMV-NMEA-2000-EN.pdf ). But we can't find the document describing the details of this message in the document.

Is that the correct PGN to read? In this case, is there any document describing this message?


Maybe the information SoC 0x0FFF (see page 25 of VE.Can-registers-public.pdf) is the correct information to get? But this information is in read/write access and we are not sure that's the right information?

Alternatively, how might we best modify the settings to get the site working properly? I am hoping I can still display SOC somehow and hopefully use voltage to temporarily control generator start / stop via the CCGX
