CANBus interface on GX
I have mainly a Victron system installed in a 5th Wheel RV; 1020W of Solar panels thru a 105V/100A MPPT solar controller, and a 12V/3000W/120A Inverter/Charger for shore side charging with a Bluetooth VE buss smart dongle. I installed it myself and used a MK2-USB to set up the Mulitiplus for the 500 Amps of AGM batteries I have. I also have a BMV-712 to monitor the system. I'm interested in upgrading to Lithium batteries and also adding one of the GX devices to be able to remotely monitor my system (I currently only use bluetooth locally).

I'm looking at Lithionics batteries, their internal BMS models have an output cable that supports RVIA RV-C and CANbus information, specifically it provides battery Voltage and Current data, battery Temperature and SOC data, remaining Ah capacity, desired charger state and charge specs, HVC and LVC status, total Ah capacity and current Power, accepts ON/OFF/Charge-ON commands and a few others. The link for the information specifications and protocols is here.

I've tried asking and looking around, but can't find anyone with answers. I would like to know if any of the Victron Venus GX or Color Control GX or Cerbo GX interfaces can accept this data from the Lithionics GTX12V315A batteries internal BMS using the CANBus data interface. And if all I would need is the Lithionics cable (75-H1FCR-CS2 Ampseal 8 Harness Kit), to plug into one of the GX's.


Also, is specific programming required for the GX?

3rd party external antenna for GSM GX

Hey everyone.

We are about to install many systems in remote places in Africa and will use the GSM GX module for internet connection. Since a lot of the places will have poor connectivity, I am looking at improving the signal with an external antenna.

However, the option offered by Victron (below pic) seems quite limited. The cable is only 0.25 meter long, you need a screw base to attach it somewhere and the gain is only 3 dBi...

[image]

Does anyone have experience using antennas from other manufacturers for that?

Will 3rd party antennas work if we make sure to get one with the same type of cable, connector and frequency ranges? Is there anything else to take into account?


Thanks in advance and much sun to all!

Has DC System - Incorrect Consumption in VRM when Phoenix Inverter is run on DC

Hey everyone,

I am running an off-grid system with a GX Device and an MPPT, BMV and Phoenix Inverter 12/800. I also have DC loads connected to the system. As long as the inverter is not running, the consumption values in VRM are perfectly valid, but as the inverter runs, the values measured are off, as the inverter power is just added ON TOP of the DC Load Power which already includes all the current drawn by the inverter.

Is there a way to configure the GX Device to ignore the AC Power measurements, as they are already included in the DC Load? If not: it'd be great to have an option in the menu that states that the inverter is run on the DC system. Otherwise I am unable to reliably log the system consumption...

Geofence - GPS / no GPS notifications

HI

Does anyone know the parameters for information update to VRM?

I have a new instillation on my boat.

(3x 315w panels / MPPT 100 |50 / BMV 712 smart / Color GX / 2x 300ah Relion LifePo4 )

Geofence looks very useful to me to know where the boat is or if it has moved.

I was trying different USB GPS modules and unplugged one that was working and fell asleep before I received notification of no GPS signal. When I plugged in a new GPS it was only a matter of minutes to come back online.

It would be interesting to know how the geofence parameters are set

Looking for input - 4 to 20mA and 0 to 10V senders

Hello Community!

We’re considering to add a USB accessory to our GX product range, to add 0 to 10V, as well 4 to 20mA inputs.

But since all of us have very limited experience with 4 to 20mA tank senders, we're looking for some input:

  1. Is it always 4mA = tank empty, and 20mA is tank is full? Or do the empty and full levels need to be configurable in a software setting on the GX Device?
  2. And how important is it that the transducer can be powered by our device?
  3. Anything else we should keep in mind when designing a 4 to 20mA input? Good features you have seen else where?

Also, if you are using 4 to 20 mA senders, please post a link to a datasheet or specs below. And if you have an opinion on the sender, what you like/don't like, welcome to add that.

Lastly, most questions above are for 4 to 20mA, not for 0 to 10V - but if you have special comments about 0 to 10V, welcome as well - obviously. The product we have in mind will have inputs that can be used for both types.


Note, that this is quite early in the product development, I can’t say anything for now with regards to availability dates.


All the best and thank you! Matthijs


ps. just to prevent any question about this: we'll soon launch a new Venus OS version that can work with irregular tank shapes, as well as naming tanks and some more features: all those features will also available for the 0 to 10V and 4 to 20mA inputs. Details here.

Venus GX Modbus TCP forwarding Solaredge PV production?

Hi !

I'm using openWB to charge my EV. Unfortunately the Solaredge PV inverter allows only one concurrent TCP connection.

That means if the GX device is talking to the Solaredge the communication to the openWB is blocked.

But I've seen in the Modbus TCP menu of the (Venus-)GX that there is an entry for the SE PV inverter. I checked so far the documentation of the GX but without success.

Can anybody explain me what this means? May be I can use it to retrieve the production of the SE via the GX device.

Thanks !

Color control gx


I would like to have a generator with auto start hooked up and have a strobe beacon which flashes due to alarms. My question is which relay inputs on the gx and quattro would you use? I'm thinking the relay on the gx would be used for the beacon. And a relay used on the quattro for the generator start/stop. Would I lose functionality if the generator was controlled by the quattro instead of the gx?

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.

I have multiplus installation 12-1200 with latest firmware 2607469, REC BMS and color gx panel. Everything works as it should, but I want to be able to deactivate charging and still be able to have 220v (passthru). The problem is that I can set the input current limit to 0 on multiplus. Have tried to disable assistant in VEConfig without success. As an alternative, I have also tried to set the charge in multiplus to 13.15v and deactivate VE.Can communication with BMS for that multiplus to balance cells between 40-60% capacity, but multiplus does not respond and continues charging up to 14V which is value BMS normally seems. Must Multiplus be reset or restarted for settings to be saved after programming with VEConfig?

using 2 x MPPT blue solar controllers into Color GX, confused about readout shown now.

Hi i have 2 x MPPT units with them both connected via VE direct to the Color Control GX panel. with my initial testing i used only 1 x MPPT unit and the icon on the display (battery) showed the correct wattage being drawn from my DC power. I also have BMV702 connected to the color control GX panel and that wattage was also consistent with the readings on the GX display.

Now i have connected my system in full, which is using BOTH MPPT controllers and both into the VE direct connections of the GX. the readings i was getting before (with 1 x MPPT) for wattage is not anywhere what it should be now the 2nd unit is in play.

with nothing but 1 x led light on in my RV connected the system power used to show 3 watts, but now with the 2nd MPPT connected the display GX and also the BMV702 show 30-40watts for same load as before. Even turning all DC loads off the system still shows 30watts (1.2amps) being drawn.

Nothing has changed except i've connected the 2nd MPPT unit which in effect doubled up my PV input. as well as that my initial testing was with 2 x 12v 190ah batteries (in series 24v) now with the full system connected i have doubled the batteries, giving me 24v @390ah. not sure then if this 1.2am (30ish watts) will 'equalize' itself as i dont know what would be drawing that extra 1amp with virtually no DC lights or accessories turned on.

Any ideas ?

Replacing Bluetooth SBS Unit with GX SVS/STS Functions

The Setup is a SmartSolar MPPT 100/30, BMV-712, Smart Battery Sense and a Multiplus 12/3000; with a Venus GX system.

Currently I have the Smart Battery Sense configured in the VE Bluetooth Network to provide Temperature and Voltage Data to the MPPT and Voltage Data to the BMV.
I have the Battery Temp Sensor on the Multiplus, plus the Voltage Sense connected on the Multiplus for its charging setup. (FWIW, I have the 2nd input on the BMV used for the Aux/Starter Battery)


The question is about using the STS and SVS (Shared Temperature and Voltage Sensing) when enabling DVCC on the GX.

I can enable those but are they actually sending info to the MPPT and so replacing the Smart Battery Sense? I understand that this function was waiting on a certain firmware/OS version, but not sure if that has arrived yet or not? My Multiplus and MPPT are above the minimum versions quoted in the DVCC text in the GX system setup. Are we waiting on a GX OS update as well? Is anything needed in terms of setup beyond enabling DVCC on the GX?

For the Shared Voltage Sense data, what device is providing that information? Is it the BMV or is the Multiplus. Does that device overide the others input in the same way that the BMV Voltage is replaced by the Smart Battery Sense voltage on the Smart Network as I understand it? (never actually checked this TBH).

If the Smart Battery Sense is connected and Networked; AND SVS/STS is enabled and working, does one have priority over the other if both are left enabled? (obviously the data should actually be identical so it is hard to be sure which is actually being used).

CCGX with multiple BMV7's ?

Hi,

I Just joined this community, and just recently started using Victron Product.

So please be gentle with my potential Noob-Questions ;-)


I'm running a small 600Watt PV of Grid installation here in Austria.

I love the overview about all the ins and outs at the CCGX.

But.:

-------------

I found out the the Victron Inverters (specially the small phoenix up to 1200VA) are not showing reliable wattages, sometimes even really weired values.

What i found out in this community is that this is hardware-based, so...without hope that any firmware update would solve this issue.

That actually makes any logging and data about my energy usage after the inverter pretty useless.

(even though it gives me an idea of the used energy)

Is this the same (none accurate measuring) the same for newer MultiPlus 500VA - 1600VA Series ???

https://www.victronenergy.com/inverters-chargers/multi-500-va

-------------------

Another "problem" in logging is that i use quite some 12V Devices in my house, driven by an DCDC Converter, so id actaully want to log the energy use of those devices wich are not driven by an inverted AC too.

What i found out until now is that victron does not produce DCDC Converters wich would be able to send reliable wattage to the CCGX (via VE.Direct).

--------------------

And, does anyone of you know/have ever doublechecked the reliability of logged data from mppt chargers like the 100/30 I'm using

---------------------

So I'm searing for the following possibilities:

two separate possibilities to measure the Wattage (expl. a shunt )


1.: should measure the Watts between batterie and Inverter (cause in that case it includes all energy losses too, and all the realistic used Energy, converter to AC is shown)


2. Wattage between Battery and DCDC Converter to 12V, or direct 24V devices


3.Logging Battery temperature (! but wired, not with the smart wireless sensor)



I'm aware of the BMV7** Series, but not sure how the CCGX would show Wattage of two BMV with two separate Shunts.......Could i set one of the BMV Shunt measurements to show up in "AC Loads", and the other BMV to show up in "DC-Power",...Or would the just sum up to one Wattage shown in DC-Power ?

And....Does the Temperature Sensor data from the BMV get transfered adn logged to the CCGX ?


greets and thanks in advance

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.

What does "System reset" on MultiPlus?

Hello,

Recently a MultiPlus 48/5000, setup as charger-only, threw a "Fault" for unknown reason and was not accepting AC-In. I first saw something like "Error 11 report", but it didn't show anything and I haven't seen it since. However, I couldn't get MultiPlus back charging. Until I found this:

I couldn't find any documentation what this "System reset" actually does, but I did click it and MultiPlus started charging afterwards!

Have I lost any settings by doing this? Or is its sole purpose to get out of these "Faults"? I'd appreciate a write-up of what it actually does :)

BTW, this "Error 11" caught me off-goard. I'm just using this MultiPlus as a Charger, so I'm bumped why it threw any error at all... Maybe someone knows how to configure it to be more resilient and robust?

Thank you!!
