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:
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.
I need some assistance. I´m installing a setup composed of a battery bank (lithium), 2 smartsolar MPPT, 1 Cerbo GX, two Multiplus II - 48/5000. (240VAC)
The system is installed and it is working fine, but I can´t find a way to only have one inverter/charge working. I understant that when configuring the inverters in split/parallel/three phase, if one shuts down, the other one also turns off.
But one this case, I don´t need to combine the power of both inverters. I have the AC-out´s connected to a swich on the AC switchboard in which we use either one inverter, or the other. So we would like to use the inverters as indepent as possible.
Right now, I have them connected to the Cerbo GX, each with their own VE.BUS cable. I´ve tried chain one VE.BUS cable from one inverter to the other and then to the Cerbo GX, but it is the same, I cannot use one inverter without the other.
Is there any workaround to this? We just want to have more redundancy with the setup, we don´t need to have the combined power of the inverters.
Tiny thing, but something I am sure will be appreciated by all installers:
On the sticker on the Cerbo, can we change the formatting to add a space or : after each set of four characters to make it much easier to read and check?
Eg. Instead of "d412430b4fa1" it is printed "d412 430b 4fa1"
I would like to use second GX device in system, but I need to use some data from first one. Is it possible to get for example battery current form first GX device and set it on second one as com.victronenergy.system Battery Current (841). I have noticed that there is new setting "ModBUS TCP Devices", but when I setup connection the result is
Or maybe other sugesstion for data synchronization ?
Hi, with the GX Tank 140 accepting 4-20mA inputs, I would like to connect various instruments other than tank level - like an inclinometer, flow meter, weight etc.
Is there a way to set custom names and units like degrees, L/s, Kg etc. instead of just L or %?
Is there anyway to see how much an power inverter is producing?
Also this would be extremely helpful in parallel systems if I could see each inverters load.
Just installed 5.21 beta VictronConnect. It upgraded my mppt smart solar to 1.48. my color control has a notification error
system warning Dvcc with incompatible firmware #48
what should I do about this error message?
I would like to know if there is any plan from Victron to certify the GX range or any specific product of the GX family to be certified in North America, such us UL or CSA certification as this is something that our clients are demanding more and more.
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...
Ok this is a strange one. When connecting to the Remote Console of the Cerbo GX via VRM my password works perfect every time.
When connecting via the IP address in a web browser it always says the password is wrong. I have reset and tried several (super simple) passwords and they only seem to work via VRM.
Once I disable the password check (Have to do this via VRM) I can get in again via direct IP on LAN. That is very insecure though.
Enable on LAN is enabled.
Any suggestions? I would like to have remote access in the event of losing internet.
My Venus GX at another site is working perfectly.
I am planning to get a lot more data to my NMEA2000 network. I have just ordered a Cerbo GX and planning to get water tank, fuel tank and septic tank data to the NMEA2000 network using the resistive tank level inputs on the Cerbo GX and the VE.Can to NMEA 2000-adapter.
My engine is a VolvoPenta MD2040 and a bit older engine without support for J1939. I am also considering several options such as EMU-1 from Actisense. But want to see if I could find a simpler solution instead.
I want to get the following data from the engine to the NMEA2000 network, hopefully using the Cerbo GX.
Is there any option to get engine data to the NMEA2000 network using the different tank, temperature and digital inputs on the Cerbo GX?
Existe t'il un moyen de désactiver complètement le wifi sur le dispositif gx equipant l'easysolar II ? Un client potentiel qui a des problèmes d'hypersensibilité aux ondes EM me soumet le problème suite à mon devis de système autoconso ESS.
7 days ago GX display on my EasySolar-II GX froze.
I did the on/off "procedure" and it came back but there was a error #10 as a result.
Is there a way to reset GX display wthout havig to reset the whole unit?
I am using a color control GX on my boats system, it is connected to a 4G Wifi router, Since this week I notice quit high consumption of data, which could only be used by the GX! (4.5GB in 5 days!)
Could it be the new version 2.60 is using more data?
And/ or will the new VRM protal use more?
I like to see the temperatur values on the display of ColorControl/Cebro GX (Motorhome & Boat View).
Is there a way to customize the view of the GX?
Hello I want to use the Cerbo GX with GX touch 50 in a place without internet connexion, there is 50 meters between the screen and the Cerbo GX, is it possible to work with bluetooth or with cable connection. ? Thanks for your answer.
I had error 7 on the display of my GX unit, then after configuring it it now displays AC1, how do i correct the fault
Can i use a GX Touch 50 on my Easysolar 2 GX to display information?
Also, is specific programming required for the GX?
Given the ongoing local grid instability and perennial rolling blackouts in South Africa, we really need a better way than email alerts to signal a grid loss.
We're currently developing a small daemon to run on the GX device to catch a grid loss and trigger an event remotely but that will require us installing that custom code on every GX device we ship and that's going to be harder than it should be.
Two solutions come to mind:
1. Allow calling a custom webhook directly from the GX device on grid loss.
2. Allow calling a custom webhook from the VRM API (configured for the site inside VRM) on grid loss.
I would prefer the first solution because it would not be delayed by the reporting interval configured on the device.
Where is this SQLite file uploaded TO???
At first instance VRM portal said it DID work.
I cannot find its destination. Where is it?
All subsequent attempts have failed?
Failing this, how do I view the data on my computer. This is all I want to do and surely it cannot be so difficult and clumsy
It seems to be pretty well documented that there are issues with ve.direct devices shuffling around device IDs in a system. This is an extreme nuisance for multiple reasons. Firstly, your device history in the GX and VRM essentially get lost. Secondly, if you have a well defined Advanced view in VRM with many widgets, these have to be redone every time the device IDs get shuffled which is a considerable pain due to the interface. While a pretty interface, it is NOT at all an enjoyable process to arrange your widgets in VRM.
I have had this happen twice now in my system in the last 3 days and it is very frustrating and really breaks your historical data used for trending and analysis.
It seems that currently, devices get tracked by their ve.direct device id (288+). This is a transient value that appears to get assigned to devices when they are connected/on power up (or if a random reshuffle occurs?) and is simple a bus communication port. Given that every device has a unique serial number (and likely other under the hood identifiers as well) why isn't data logged against that vs against the device ID which seems to change randomly without reason. This would represent a much more "stable" view into your data and allow me to trust the long term trends much more.
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?
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
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.
Some details on the system
Quattro 15000 with fronius 6k ac coupled on ac 1 out.
Honda eu7000is backup generator.
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?
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 installed a second Multiplus II 3000/48/35 this week. The system have now 40 Kwh Lifepo4 (BMV 700), 2 x MultiPlus II in parallel, master unit with current transformer, Fronius IG connected to ACout with ET112 and MPPT 150/45 Charger.
The -259W on Grid is not correct… external meter shows near 0 watts. The real house Loads in not 271W, but 271W+259W
Till last week (with one only Multiplus) I haven´t this problems. What I have changed:
- Multiplus with 2629473.vff firmware
- Venus GX from V2.51 to V2.53
Can the relais be used as a programmable timer? Through VRM the device has the time so it should be easy. I cant find any reference though.
GX GSM is not on my settings list , so can't get GSM too culminate with Easysolar 48/5000/70. Have checked SIM in another phone and can call and receive calls on an old phone in exact location of GSM Aerial ? Can someone please help . It is an optus SIM in Australia
