I have a small system with (2) 100/30 MPPT charge controllers, 800w of solar, and a single Multiplus 3k inverter/charger.

When I attach everything to a Venus device (RasPi) the MPPT devices are showing up under the Inverter control tab. Why is this happening?

I have a raspberry pi that communicates with the Cerbo GX and the Multiplus 2 through the modbus registers in codesys. However, when trying to write the register 62 to perform a system reset when the relay test is not completed and in pending mode, when trying to write this register the whole multiplus modbus tcp communication will not be stable anymore. Like literally it could break the modbus connection with the moltiplus randomly. Is there any explanation for this? Thanks in advanced!

Hi, I can see vedirect-dbus running on my rpi4 and am interested in the source code but can't find any reference to it. Is this open source - and where might I find it ?

I love being able to monitor my system with the vrm portal, its a 48v lifepo4 system but I have a blue smart ip67 charger for my generator 12v starting battery. Is there a way to get that charger to talk to my my raspberry pi running venus os (or a cerbo gx for that matter) so that I can monitor the health of that starting battery remotely and even control the blue smart charger? If not what is the best way to get a voltage reading from that battery into my vrm portal?

Hi Everyone,

I just wanted to know if there are any issues using Raspberry Pi over a Cerbo GX, I I was looking at some YouTube vids and they said there was an issue with the pi going to certain firmware updates that it erases the user settings so they have to be set again. Is this the same for the Cerbo GX or does that keep all of its settings after update?

When I power on the RPI the dashboard function always asks a UI redeployment. A small modification (move a node for a few mm) and deploy restarts the dashboard. How can I avoid that?

I’ve had my system running in a camper for about 2 years. Since the new year I’ve been getting regular loss of communication alarms, whilst parked on my driveway.

In the past the 4G modem (TP link archer mr-600) has been the culprit, but the of thing is the router is still online. In fact the only consistent way of fixing the issue is to reboot the router.

It’s throwing me a bit because the router is still online and showing the Victron pi connected to it.

The router firmware is up to date.

The Victron Pi was running 2.85-large, I’ve just updated this to 2.89, which is the newest available within the unit.

Bonjour,

je dispose d'un véhicule possédant une installation solaire (BMV 702, Multiplus 800Va, MPPT 100/30, MPPT 75/15, VenusOS) et pour lequel j'ai configuré l'assistant ESS. une simple rallonge est branché entre le véhicule et le logement dont je suis locataire.
Le mode ESS marche a merveille ! Je souhaiterais pour ne pas modifier le réseau électrique existant du logement utiliser les données fournies par le compteur Linky afin de transmettre ces dernières à l'installation solaire afin de limiter la quantité de surplus injectée dans le réseau. Je sais qu'il existe l'ET112 pour ce genre de cas mais je souhaiterais ne rien modifier et donc utiliser la téléinfo du linky pour récupérer L1 et ensuite le transmettre au VenusOS via modbus pour piloter l'assistant ESS.
Quelqu'un a-t-il déjà mis en oeuvre ce genre de chose et pourrait m'aider à reproduire celà ?Je suis inculte en python et modbus donc un p'tit coup de pouce serait vraiment apprécié ! D'avance merci à tous pour vos retours !

I want to monitor my Generator output. I am using the Venus OS on my Raspberry Pi. I found the Victron Energy Meter Et112 and have a few questions. 1. Which CT do I use to get amperage reading. 2. Does it read frequency?

Hi,

i want to install a Photovoltaic System in Zero-Feed Mode and Fronius symo 8.2-3-M.

I want first only run the System without a ESS but with the opinion to add it later. Is it possible to run the System at the rasperry without a Multiplus first?

Thanks a lot

Hi everyone.

I'm developing a energy transfer system and I've a question about the monitoring and control. I'm using pylontech batteries, quattros, and fronius pv inverters in my system. What I want to make is a Python program to include AI in the control of the system and for that I have my Raspberry Pi. I also have a cerbo GX. I think I have two options:

I can use the cerbo just to communicate with all the devices in my system. By doing this I will take advantage of the great communication system of the cerbo. Then, using modbus TCP I can adquire the data I need from the cerbo to the raspberry PI (Using the modbus tcp register list).

The other option is to communicate straigh between the raspberry and all the devices, using adapters for all the comunication, as the raspberry only has usb connection.

I know that the second option is obiously more complex, but the point is that I don't know if with the cerbo in between I will have access to the same information than in the second option, and that is my question of what to do.

Thank you.

Dear All ,

As far as I understand there is a way to change the inverter lower cut-off values for battery voltage.

when I installed the Inverter I didn't change any of the default settings ( I think, I couldn't get the software to work on my pc ), and now I have an issue with the Inverter not working under 24V when the battery bank gets drained under 24V

The main question is, IF I can change the setting for the lower cut off value from my raspberry pi running the official Generic Venus Device image and uploading data to the vrm of Victron.

and this preferably to be done remotely since I can't physically get to it.

Thank you in advance

The harvester.

Hi everyone,

Can someone give a bit more clarity on how to bring the Multi RS in VRM?

The manual is... limited in this regards.

I have a CCGX (on my existing quattro installation) and just bought a RaspberryPi on which I installed VenusOS and I also purchased a MK3 adapter.

From what I can tell, only VECan is available on the Multi RS, but when I connect to CCGX it won't show anything. Do i need the little RJ45 end plugs (which didn't came with any device...) ?

What would I need to connect it to RPi?

Thanks

Romeo

What's the easiest way to control a 120V outlet, based on outdoor temperature, using the Venus OS running on a Raspberry Pi 3B+?. I've updated the OS to version 2.92, and have ordered several Ruuvi sensors. I also have the Victron Smart Battery Sense module installed.

I store my off-road camping trailer high in the Colorado mountains, where we have many nights with temperatures below the 25F threshold for my LiFePO4 battery. It's plugged-in though when stored, and I have a battery warming wrap -- I just don't want to leave the wrap plugged in all the time.

I'd love to be able to use something like a TP-Link smart outlet (WiFi), or anything Zwave or Zigbee would be fine too. I'd also consider using DuPont wires off of the GPIO pins on the Pi, though that would be my last choice as the length of these control cables seems pretty limited.

For those that have something like this setup -- what are you using, and has it been reliable?
