Venus GX - VGX

I'm replacing my almost-failed AGM batteries with PylonTech.

What is 'best' or 'accepted' practice to connect the venus (power) to the batteries? There is a diagram i found which shows the gx powered off the Multiplus battery terminals. Presumably somehow terminating the power leads with 8mm lugs. sticking the bare wire under the nut doesn't seem right...

The gx has a fuse in line, but i'll also include a switch.

Is that best, or should i power it off either the 'output' side of the battery main breaker, or the 'input' side of the main breaker. In which case, i'd have to also provide a negative bus connection point as well.

Good Day,

I just installed a parallel system(multi 3000/24) . all is well with this system except for the VRM, its doesnt report any AC input or AC loads. The DC loads are also high as i only have a BMV connected to it .

Firmware version in gx is v2.87

Hi Victron Community

I‘m using a CCGX and I like to add some Ruuvi Temperature sensors. Since the CCGX has no bluetooth I‘m wondering, if it is possible to add them via adding a bluetooth dongle?

Hi there!

After swapping the Venus (replacement) I can see all devices BUT the PylonTech US2000 stack.

Three stacks 4 batteries each going to the hub as before.

CAN iin Venus s at 500kbs.

If I connect only one single slave battery (DIP0000) it shows up right away in the Venus. If I connect one stack (DIP0100) nothing shows up. Same for the hub (DIP000001)

Before swapping the Venus it worked as it is!!! So what detail in programming the Venus am i missing..?

Have a nice day and hopefully til soon, Flow

I am trying to programmatically set the state of Relay 1 on & off on a VenusOS on an RPi via sending the following command but the change is not applied. Relay 1 function is configured as an Alarm Relay.

dbus -y com.victronenergy.settings /Settings/Relay/0/InitialState SetValue %1

While dbus command returns a successful result the "Alarm relay on" toggle switch in the UI under settings->relay does not reflect the issued command.

I can programmatically change the Function & Relay Polarity and the change is reflected in the UI immediately.

I looked at the var/log/localsettings/current file and confirmed that the UI and CLI command is affecting the same setting.

@400000006106581304f7c444 INFO:root:Setting /Settings/Relay/0/InitialState changed. Old: 1, New: 0 //UI "Alarm relay on" Setting Change
@4000000061065c1c04621bc4 INFO:root:Setting /Settings/Relay/0/InitialState changed. Old: 0, New: 1 //CLU dbus Setting Change

Has anyone else had the same issue before?

Funny story. After perpetual problems getting a clear view on the "north side" of a Venus GX (see https://community.victronenergy.com/questions/124882/venus-gx-one-or-two-usb-host-ports.html)

And for future generations - here it is:

[image]

A customer said the Venus GX swallowed the microSD card he tried to insert. Needless to say, a microSD card is not recognized. I asked him if he didn't throw it into the USB port. Allegedly no.

But - given the scarcity of north views, he used this picture I sent him:

[image]

"I tried to insert it as is pictured"

Now I'm getting a very bad suspicion. You see in that picture the microSD seems to be exactly mirrored to what the picture on the VenusGX casing says. I hope (and that would be my question) that's not the reason why a microSD card would simply fall into the Venus GX.

So we will now have to go to the installation, dismantle the VenusGX and see where the SDcard went. As I said: funny story.

I'm looking at the tech specs of a Venus GX which say there are two USB host ports. Looking at the Venus GX "high quality photos", there seems to be only one. So which one is it?

- Connected GX device in ES II to mobile hot spot on my phone. (Built in AP on the GX is enabled)

- Left ES II ON for 1 day. When i come back, GX doesnt auto connect to my phone's hot spot - doesnt even see it as availabe. So i cannot connect to VRM and send data from last day.

Must reboot GX device, then it will find phones hotspot, and correctly connects to VRM and sends data.

Will i need to reboot GX everytime i come onsite?

We had a 2hr network router problem. Other devices were connected but the Venus was not. I rebooted the router and the Venus after.

Data for the duration of the 2hr network problem was lost. Any idea what causes this data loss?

Hello,

I have one doubt about smartshunt...

I would like to use it in DC only sites, with just an MPPT and maybe a monitoring device (Venus or raspberry). In this situation, if I add a smarshunt to have SOC reading, can I create a bluetooth network and read it trough the MPPT (smart model) or do I need to also connect it via Ve.Direct/ USB to Venus/ raspberry?

Will it appear as a valid Battery Monitor in VenusOS if connected trough bluetooth to the Smart MPPT ?

Hello, in order to use ESS, must I have a GX device such as Venus or Cerbo? If so, which is better?

Bonjour,

J'aurais besoin d'informations pour une installation en site isolé.

Mes équipements :

CCGX avec venusOS 2.87

Multiplus 5000Va/48v

MPPT 150/85

Onduleur sma 3kw avec AC sensor

Batteries pylontech 48v

Convertisseur CC 48v/12v

BMV 48v pour convertisseur 48v/12v.

1. Quel est l'assistant à utiliser actuellement ?

J'ai mis : "aide à la convertion" et l'assistant "mesure compteur 220v" (ac sensor).

Ou puis-je trouvé les informations de configuration pour site isolé ?

J'ai suivi une partie du paramétrage de l'ESS pour le multiplus Veconfig. Et j'utilise le DVCC. Merci

Merci de votre aide

Cordialement

I'm looking for a way to remotely switch my Multiplus II between inverter / charger mode.

This is essentially due to the variable tariff I'm on, I've got a script on a Raspberry Pi which looks at the day ahead and plans when to charge and when not to.

I gather there is something with node-red, maybe MQTT, but ideally I'd love to control a relay on an Arduino to input to the Multiplus or Venus GX to tell it the mode - is this an option?

If not, MQTT is my second preferred option of those I gather exist - can I request this via this method?

I've found out, that despite the Multi being switched off in this boat installation for most of the time (to conserve power), VRM reads the battery temperature from its sensor (see the first screenshot attached). Can the MPPT 75/15 being set up as DVCC with STS turned on, read the battery temperature sensor (while the Multi is switched off) in this installation?

In an older thread, I saw the answer that, the Multi should be in charger only mode at least to read the battery temperature, but still, some more clarification is needed as you can see the VRM reads temperature from the Multi's probe despite having it switched off.
