I have a LG Chem RESU10 connected to Victron Multiplus 48/3000/35-16 and Victron Color Control GX. The Battery is recognized and shown on the GX. But when I put two LG Chem RESU10 onto a RESU Plus and the RESU Plus to the GX, the RESU Plus and the batteries aren't recognized and shown on the GX.

Cabling is checked.
Has anyone worked with this constellation?

Hello!

I have noticed that when I run my generator that the DC load shown on the remote console or the HTML5 app is fluctuating wildly. In the video below my real DC load is almost constant: internet router, Venus GX, and two LED strips.

Any ideas?

My guess is that it is the AC-in that is fluctuating and the DC load is calculated incorrectly.

Hello. We added 8 new VenusGx+GSM GX.

5 are working properly, 3 give such an error (screenshot).

SIM cards are working, they checked that the Internet is there. Firmware 2.33.

What could be the reason?

A Venus GX was acquired for an isolated photovoltaic installation of 1.08 kWp, before it showed on the cell phone the Wi-Fi network that Venus has incorporated, but throughout the day it has not shown any network, what should I do ?, thank you very much.

Can I connect a CCGX to a Venus GX to use as the display? I want the connectivity of the Venus (tank inputs, temp inputs, etc.) without having to purchase all of the external VE. Can tank adapters (too expensive). If not, I really just need a way to have a small permanently mounted control display near the rest of the distribution panel in the van. I know I can control and monitor with a phone and tablet, but also want something mounted permanently. Thanks in advance for your help.

Hi Victron Community,

I am currently setting up a grid parallel ESS with a Multiplus 2, a Venus GX and two 5KWh Tesla (24V each) Modules in series. I will setup a BMS (SimpBMS) for the Batteries in the future but would like to use them beforehand (with restricted parameters of course to ensure that they don't under and overcharge ).

I am struggling to find a battery option in VE-Config and on the Venus Remote to tell the multiplus to charge/discharge the batteries according to voltage. All options in the ESS Assistants appear to be requiring a BMS communicating to the GX/Multi that batteries are charged/discharged.

Isn't there a simple option where I can set the Multiplus to charge the Batteries up to 48V max and invert down to 38V, for example?

After starting the ESS Assistant I have changed the inverter and charger settings in Ve-Config manually to the above (38V - 48V), but the system does not engage and appears to be waiting for a signal from a (non-existent) BMS.

Is there a "BMS off" or "No BMS" function (or similar) on the GX that I have overlooked? Any help would be much appreciated.

Many thanks

Hi !

I'd like to mount my Venus GX to the DIN-Rail. Is there an adapter kit available?

I was searching the Victron websites but I was not successful. For the upcoming Cerbo GX it seems to be included.

Thanks,

Dirk

I have enabled Grid Failure alarm on the Venus GX coupled to a Multiplus. When Grid failure occurred I immediately got a notification email. When Grid was re-established I also received the VRM Notifiier email which said Grid Lost has changed to Grid Established . All good. 12 hrs later grid failed again but I never received the notification. Other parameters which I have setup to inform me when grid fails such as " no input AC " did work and I got the notification. When looking at the Alarm Logs on the VRM Portal it does not even show that there was a grid failure at the second occurrence. During the second grid failure period I looked at the Remote console and there was a Grid Failure alarm flashing . So it seems one has to acknowledge a Grid failure alarm before it will retrigger a second alarm even after the alarm has cleared . Seems like the Grid Failure algorithm needs to be looked at .

How can I use one of the relays in the Venus to turn on a fan, when the temperature is 25F higher than the outside air ?

This way it will turn the engine room fan on, BUT only when needed?

Is there a way to keep the device numbers from changing if I am doing some maintenance on the configured devices? Right now its just annoying, but I can see that getting to be an issue in the future where there is history I want to keep in the portal. Thanks, Bill

The main color screed I see remote'd into the VGX has AC loads, Tanks & Pump listed. I am not using those in the foreseeable future and would like to remove them. Is there a simple way to do that? TIA -Bill

Hello all. Here is a second question getting ready to do a Victron system install in my class B RV (Roadtrek). I will have a CCGX display with Multiplus and BMV 712 and Victron smart solar MPPT installed. Also, when the Orion TR Smart DC-DC is released I will install it to control alternator charging of my new lithium batteries. Is there any reason I would need to install the Venus GX since I will have the CCGX already?

I gather that the only benefit of having the Venus GX in addition to the CCGX is being able to connect holding tank sensors to the Venus GX to have those readouts. That is intriguing but I am not sure if the rudimentary holding tank sensors of the stock Roadtrek are going to be usable with the Venus GX.

So, is it correct thinking that other than the holding tank connection, the Venus GX install would not add any benefit or additional usability that the CCGX already provides?

Thanks!

My system (MultiPlus II 48V 5KVA + Venus GX ) recently stopped reporting stats and was no longer reachable which meant I had to restart it.

In my setup the Venus is plugged directly to the batteries (as seems to be recommended) which makes power cycling it a bit tricky. The easiest way for me to do this was to disconnect the the M8 eyelet connector from the MultiPlus DC input where it is installed. This lead to fairly heavy sparking on reconnection.

As far as I am concerned, the Venus does not have a huge power draw and I cant imagine there is a large inrush current when connecting it. During installation I actually connected the power by plugging the green terminal block connector into the Venus. This caused a spark at the terminal block and a very significant spot weld. The practical upshot is that the block connector is no longer removable due to the spot weld which is why I have to disconnect on the MultiPlus side.

Is this kind of sparking to be expected? The fuse is not blown and the Venus seems to be working fine after the restart. If the sparking is expected can someone explain why this is the case?

The Venus is essentially an off the shelf consumer grade RPI thingamajig (beaglebone I think) that has been hardened and extended. As far as I can tell it has its own power supply to convert the wide range input voltage down to something the board can use, and has an add-on board for all the Victron communications busses. Finally the whole thing is conformally coated to protect it (nice!). I mention all of this because similar consumer grade product generally do not spark like this and I was pretty disappointed by the spot welded terminal.

I am just trying to understand if I am possibly doing something wrong or if there is some technical explanation that explains what I am observing.

Thank you.

I am hooking up 2 Smartsolar 100/50's, BMV712, SBS & RPI-Venus GX to update VRM. My BMV712 will be mounted forward in the RV, far away from the controllers and I am positive the BlueTooth will not be able to connect to the VE.smart-network via the BT. I was hoping there was a diagram the showed how to hook these up so they all communicate but so far, my search has not found anything.

Currently the RPI-GX connect's via VE.Direct to USB interface cables to the SS CC's. And my guess is the BMV will need to be connected the same way?

Hi

I am having problems with the Venus GX (firmware v2.33) not recognising my MultiPlus-II 48/3000/35-32 (hw rev 08, firmware 462) inverters after I make any programming change to them using VEConfigure. (Venus console shows "Connected" as "No" under "Device List > MultiPlus-II 48/3000/35-32 > Device")

Here is my test procedure to demonstrate the problem:

1. Take a single inverter and configure it as a 1 ph phase system using VE.Bus System Configurator (v 90.09.141) using a MK3-USB. Don't do any programming using VEConfigure.

2. Disconnect the inverter from the MK3-USB and connect it to the Venus GX. The Venus GX will recognise the VE.Bus system (Connected shows Yes)

3. Reconnect the inverter to the MK3 and use VEConfigure to change any setting (I used "Overruled by remote" tickbox on the General tab). Click Send settings and send modified settings to the device.

4. When I now connect the inverter to the Venus GX it will no longer recognise the inverter (Connected stays No) even after selecting Redetect System from the Advanced menu, or rebooting the Venus. THIS IS MY PROBLEM. Possible bug?

5. REconnect the inverter to the MK3-UBS and send the grid configuration to inverter again.

6. Connect the inverter back to the Venus GX. The Venus GX now correctly recognises the Multiplus II again (Connected shows Yes).

This seems to be a similar problem to MultiPlus II 48/5000/70 only shows "VE.bus Device" on Venus and VRM

Another oddity I encountered is I cannot change phase masters. If I try and designate a new phase master using VE.Bus System Configurator the Venus will no longer detect the inverters (Connected alternates between Yes and No). If I change the config to make my original (first config using VE.Bus System Configurator) phase master the master again the system detects just fine in the Venus GX.

Any ideas?

I have activated the Grid Failure facility on my Venus G device - now how do I set up the reporting of it on the VRM portal? There is no such alarm in the pull down menu for the Venus device

Hi

having a bit of issues with vrm last 24hours. First no update for 8 hours, them it suddenly appeares, now no new update for 18 hours. Any known common issues currently?

Hello. Look at this picture. In 2 days a big drop in voltage. Only venus , bmv-712 and a ruter connectet. Batteryes is 8*150 amp. 11/11 was 12.6v12/12 was 12.25v. and today 10.3v

Hi

Is it possible to use the the two relay outputs of the Venus gx independently ,for example relay1 is used for a generator and relay 2 used for a pump or Temperature

I currently use relay 1 for generator but would be useful to use relay 2 aswell

If the relays can be used independently could you please advise how this can be achieved

Thanks

If I connect a VE. Bus BMS (connected to Victron Smart LiFePO4) and a Skylla IP44 to a Venus GX, will the BMS be able to control (disconnect/connect) the charger without additional devices (remote disconnect)? Or, must I use the BMS charge disconnect output?

System devices - Bmv 700, 2x 100/20 48v MPPT chargers, multiplus 3000/48v inverter charger through a VenusGX controller.

BMV connected via ve/USB, mppt’s via ve direct and inverter by be bus.

Phantom devices include Quattro inverter, MPPT charge controller, various batteries and tanks.

This is a new install, all new equipment, there are no other users Victron devices within wifi range.

Thanks

Mick.

Can the Phoenix Smart IP43 Charger be remotely switched on/off from Venus GX (when connected via VE.Direct)?

Dear all,

I have a LiFePo Battery which is connected to a MPPT 150/35.
The MPPT is connected to a Venus GX via VE.Direct.
The Venus GX has a temperature sensor connected.

I need to disable the charge of the battery below 5°C.

My first idea was to setup a VE.Smart Network with a Smart Battery Sense, but in the FAQs there is information not to use this if a Venus GX is connected.

The next idea was to use the Venus temperature sensor with the "Shared Temperature"-Feature, but I found out, that this was planned for Venus OS v2.20, but then not released.

I have read that "Shared Temperature" is only available in connection with a BMV-702.

So the only solution is to use a BMV-702 with a temperature sensor and the "Shared Temperature"-Feature enabled in the Venus GX or is there any plan to include the Venus Temperature Sensor in the near future?

What is the best solution for a temperature cut-off in combination with a Venus GX?

Thank you

Martin

Evening, am based in Zimbabwe, have set up 2 Victron Quatrro 8Kva systems, each with 12 x Jinko 385watt Mono panels, through Victron MPPT 150/100 smartsolar can, 3 each pylontech batteries -

1st - AC1 in is either generator or grid, no AC2 in connected

2nd - AC1 in is generator, AC2 in is grid

i used the "other - not compliant to any grid code standard" in the grid code selection

[image]

then used the ESS assistant

[image]

on the venus GX - as attached

[image]

[image]

this works fine when i have grid power - there is no feed in to the grid - when i set the grid set point above 300watts.

however when i run the generator during the day when there is plenty of sun on the panels, but generator power is required to run other loads not connected to the inverter, which feeds either into AC 1 in or AC 2, as there is ESS enabled, this seems to cause the inverter to hum loudly and switch between mains and inverting very rapidly

is there a way in which i can shut down the ess when i run the generator - or is there another way in which i can set up the system to run but make maximum use of the panel array wheter i run generator or grid?

thanks

cheers

How to connect a Venus GX to my Phoenix 5k Inverter with firmware xxxx1xx?

What kind of cable is needed?

Comparing VenusGx with OctoGX I was puzzled with the following:

[image]

Is this really correct?

Aren't the VE.Direct device limits swapped ?

Can you confirm the RAM spec is ok?

Hi,

On a venus GX , Is there a way to change relay state according MPPT or battery voltage ?

If possible, how to proceed ?

Regards,

What am I doing wrong here?

I have been trying to get the system to recognise the ET112 energy meter but no can do.

I have a Venus GX device (Firmware v2.33) connected to a Victron USB RS485 cable which is connected to 10m of Cat6 FTP solid core cable which is connected to the ET112 energy meter in my consumer unit.

Venus GX --> USB to RS485 cable --> 10m Cat6 cable --> ET112 energy meter.

Please see pictures below for actual wiring connections.

Upon connecting to Venus device I see multiple flashes of the red led only on the Victron USB to RS485 cable.

I know its trying to tell me something about the connection but I have no documentation explaining the meaning of the flashing sequence. All I can guess is that its telling me the connection is at fault somewhere.

I then found Carlo Gavazzi UCS (Universal configuration software) which runs on Windows 10 and is designed to talk to the ET112 energy meter and configure it and just check that it is working.

I then unplugged the USB to RS485 cable from the Venus GX and into my laptop running this software.

You guessed it, It came alive.

The UCS software immediately connected to the ET112 via the same wiring and I could see that it was working!

It would seem that the wiring from my consumer unit to the USB RS485 cable is correct for the Laptop but for some reason is not acceptable to the Victron Venus device.

So if anyone out there can look at my setup and hopefully spot what I am doing wrong I would be most grateful.

I have some further pictures showing the UCS software settings.
