Sur une de mes installations, avec un EasySolar II GX 48/3000 et des batteries Pylontech, le MPPT (interne a l'EasySolar, donc) a disparu du système (sur la vue sur VRM) et ne chargeait plus.
Un reboot du GX et tout est rentré dans l'ordre.
Il y a eu à priori un orage au moment de la "disparition" du MPPT, donc peut être une perturbation qui a fait planter l'appareil.
Le problème, c'est que je n'ai pas trouvé comment ajouter une alerte mail en cas de disparition d'un appareil. Du coup, comme c'est un site isolé qui n'est pas habité en ce moment, si mon client ne s'était pas aperçu et inquiété de la baisse inexpliquée de l'état de charge, ça aurait fini avec des batteries à 0, et un système totalement arrété...
Donc question : est-il possible de mettre en place ce type d'alerte, et comment ?
Et sinon, est-il envisageable qu'il y ait une option dans le menu GX pour que l'appareil reboote de lui même en cas justement de perte de communication avec un des éléments du système, comme on peut l'avoir en cas de perte de connexion internet/vrm)
The GX device is supposed to get its power from the VE.Bus BMS' load disconnect pin per the manual.
The GX device controls the BlueSolar MPPT through VE.Direct.
In case of depleted batteries, will the GX off state default to letting the MPPT charge or not?
I'm designing my future system and wondering whether I need a (Cerbo/Venus/?) GX control device in order to set the Quattro to use the batteries (and solar panels) as much as possible, until they reach a given threshold (50%) when the shore power takes over. (and ideally if/when the inverter can't keep up)
All the guides I've seen so far call for an ESS system which requires a GX device, but it seems to be a rather straightforward setting that I should be able to set with the USB interface which hopefully works on Linux.
The charger would barely ever be needed so I don't need a straightforward interface to it.
I've attached a diagram of the current state of planning below:
This new version of "REC-ABMS for Victron CCGX" communicates with a GX Device using CAN. It sends Max Charge Current & Voltage and Max Discharge Current along with Battery Voltage, Temp & SOC. The GX Device uses DVCC & SVS to control all Inverter / Charger & MPPT Solar controllers to comply with the charging / discharging limits. Ok, so that sounds good, huh? But I also want to have contactors set to voltage levels in case the CAN bus goes down.
The previous version of the BMS suggested just the traditional two contactors - HVD & LVD to provide High Voltage Disconnect of the charge bus and Low Voltage Disconnect of the DC load bus.
But this version offers a Main Contactor for both HVD & LVD for Victron inverter / charger devices. And another Contactor expected to be used for HVD on non-Victron Charging sources. And though it is not shown in this diagram, I am sure they expected a third contactor for LVD to disconnect DC Loads.
Is this genius or overkill?
I questioned the new functionality, and the manufacturer offered to disable it to make it functionally equivalent to the old version. But I am an Engineer, so I tend to think "here is a Solution, now lets go find a Problem..."
Any thoughts appreciated.....
I was expecting the fail-safe MultiPlus Inverter/Charger control to be made with a Charge Control signal to AUX1 and Discharge Control to T1 with the Assistant loaded "Two wire BMS (016A)"...
But they are suggesting Charge Control using the Assistant "Input Current Limit Control (0142)" and the AUX1 signal. And programming the Inverter's DC Input Low Shutdown voltage for Discharge Control.

When the VE.Bus BMS is configured in my MultiPlus II (48/3000/35), the remote on/off/charger-only options are disabled on the gx devices (Cerbo GX). What is the technical reason for this? Is there any workaround available to put the Multi into charger only mode from the Cerbo?
I am pulling data off our Multiplus through the Venus GX. I look at the below data field. What I see is that the value for this field is either 0 or 1. For my BVM devices it will provide in the same stateofCharge field a value between 0 and 1 representing a % of charge. Anyone have insight the multiplus values are not reflecting of battery charge level. In the below "261" is the Victron ID of my Multiplus.
Good Evening Victron Community,
I have installed a Multiplus II GX in a topology with all Non-Critical Loads upstream of the AC Input. Critical Loads on AC Output 1 as usual.
When installing the External current sensor on the Main Circuit and returning from an Outage the Inverter gave an Error 24 related to the backfeed relay.
Although the error makes sense to me regarding it seeing Current (from the external sensor) while it was expecting no current (Ac-In relay open) I would think that selecting the External Current Sensor Connected tick box in VEConfigure would tell it to ignore this discrepancy?
I have since removed the Current Sensor (and unticked the tick box) and have tested the exact same outage successfully without Error24.
Although this post mostly serves as a possible bug flag, I would like to end it with a question.
Would it be possible for me to install a three phase Grid Meter upstream of the AC Input and non critical loads (Carlo Gavazzi 65A) instead of the Current Sensor and still avoid this Error 24 Situation?
If yes, would I be able to add an unpowered USB hub onto the USB port to have both an external Wifi adapter and USB to RS485 adapter on the GX portion in order to connect the Grid Meter?
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?
