VE.Can

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.

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.

We are to install Trojan Trillium LiPo Batteries on a vessel that will have 8KW Quattro's and a Colour GX system, the Trojan lithium batteries have an inbuilt BMS that can communicate/ report status via CanBus.

Can I connect and display this information on the Colour GX using the VE.Can connection?

I will be installing a Victron MPPT to control my solar charging and i'd like to be able to see this information remotely.

I currently have a BMV-712 connected to my NMEA network with a VE.Direct-NMEA connection.

If I connect the MPPT to a Venus GX with a VE.Direct cable and then connect the Venus GX to the NMEA network with a VE.Can-NMEA cable, will the Venus GX "see" the BMV-712 that is on the NMEA network?

Can the Venus GX transmit any other information that is available on the NMEA network to the VRM (wind, speed, depth etc.)?

Dear Victron exprerts, please I have question about device control function via CAN Vreg messages, in documentation is described 0,1,2,8,16 bits in 0x0202 register for set device mode on/off/inverter,charger only. But I would to know about VE.Regs or NMEA2K supports any other remote control functions like: force discharging, set power , current, charge setpoints.

Thank you

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?

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

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?

Thank you so much for your help!

Cyril

I am building a ve.direct/N2k interface for my Bluesolar MPPT 75/10 and hopefully have the information displayed on my MFD.

The Bluesolar with ve.can interface are supposed to transmit this PGN but detailed information is missing in all Victron documents I can find.

This is what I know from NMEA.org

NMEA.org:

127750 Converter (Inverter/Charger) Status

Field # Field Description

Provides both state and status information about a Charger, Inverter or combined Inverter / Charger.

1 Sequence ID

2 Connection Number

3 Operating State

4 Temperature State

5 Overload State

6 Low DC Voltage State

7 Ripple State

8 NMEA Reserved

What I am missing is data types for each field and what data to expect.

Urban

Hi,

There is an installation I am involved with where during commissioning the shunt was installed with the batteries on the right hand side and the loads / charging sources on the LHS. Is there anyway to solve this remotely? i.e. teach the shunt to recognise current flow in the other direction?

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

Greetings victron community.

VE.Can and VE.Bus, the internal cables connected to the RJ45 protocol? Serves the same connector for VE.Can and VE.Bus? Are they going straight from male to male or are they crossed?

Of being different that the protocol or the order of the colors has the VE.Can and the VE.Bus.

I am using CCGX latest version latest firmware

thank you
