Looking for input - 4 to 20mA senders

Hello Community!

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:

  1. Is it always 4mA = tank empty, and 20mA is tank is full? Or do the empty and full levels need to be configurable in a software setting on the GX Device?
  2. And how important is it that the transducer can be powered by our device?
  3. Anything else we should keep in mind when designing a 4 to 20mA input? Good features you have seen else where?

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.

How to get USB Venus-data tar file to unpack

I asked this in the modifications space earlier this week I wonder if it can be answered.

Referring to implementation notes it says:

Also if venus-data.{tar.gz,tgz,zip} is found on removable storage (usb stick, sd-card) when booting, it will be unpacked into /data. Implementation details in this commit. Added per Venus v2.30~28.

However this is not working for me in Venus os 2.53.

I have traced through the init.d logic.

Execution of either of the scripts:

                  
  1. /etc/rc5.d/S30update-data.sh
                  
  1. or /etc/init.d/update-data.sh 

Works fine and reports: "Updating /data with /media/sda1/venus-data.tar.gz"

And the contents are correctly installed on /data

But this is not happening when rebooting.

What am I doing wrong?

More diagnostic information is in my post in the modification space.

How to use Ve.Bus Diagnostics to troubleshoot issues?

I have been experiencing a recurring error 17 problem with a parallel 3 phase
system of 6 X Multiplus ii 5000.

The Ve Bus diagnostics look useful for diagnosing comms problems and I have been trying to use them to check the Ve Bus
communication health and it gives the result in the attached photo.

There should be 6 inverters present, and there are only 5..... L2 Slave is missing. The numbers are also high.

How do I interpret this data?

I assumed from the data that L2 slave was perhaps not communicating reliably, so I exchanged that inverter for another, but there was no change in the data.

I note that there have been previous posts also asking for this information.


Any help would be appreciated. ( Even if it is to know that this data is as yet unreliable but watch this space!)

Thanks,

Multiplus and his function states

Hi all,

I would like to know behavior of Multiplus unit 24/1600-40, when I'm going to change Multi's state by SW & Modbus ("On", "Inverter only" / "Charger only".

Presumption: There is another, smaller one, inverter connected to Multi's AC input, they both use the same battery. No grid code entered to Multi, UPS function of Multi is off, Venus GX or similar.

1. What is power consumption of Multi, when the Multi is switched by SW to "Charger only" state (power limit of Ac input is set to 0A = Multi works as pass-through device = no charging of battery, AC input feeds load)

2. Can I use Power Assist function for this setup (state "On")? Could it be harmful for smaller inverter when Multi will stop assistance due to small load? P.S.: I know about “Minimum shore current limit” of above mentioned Multi.

3. Is there any output power interrupt, when I'll do SW change of Multi's state in any possible way (Inverter only > Charger only, Charger only > Inverter only, On > Charger only, On > Inverter only, ...)

4. Is there necessary to set something else?

Thanks in advance for valuable feedback J

Venus GX 2.42 CAN Bus Connection - What can we see?

Hi, today I connected my Venus GX V2.42 to my NMEA2000 network by terminating an n2k cable to the CAN2 screw terminals and into the network backbone. I now have three devices vsible on the network from N2K Analyzer and also my Simrad MFD's.

Device 1 is Quattro - Shorepower data displaying AC Voltage, Freq, Current and Power etc
Device 2 is Quattro - Inverter data displaying AC Voltage, Freq, Current, Power & Battery V and I
Device 3 is the Venus GX - Displaying product data but not much else

I was hoping that I would also be able to access the following;

BVM7XX Battery Voltage, Current, SOC, Temp, Aux Voltage for each BVM on the system (I will have 2 or more)

Tank data / Digital Inputs

MPPT Controller Data (I have 2 on my system)

Lastly, my Quattro unit is Version 1.0 - does this need an update? I have experienced problems lately where the inverter output drops off for a period of time before coming back on. When disconnected from the Venus the unit seems to be stable.

Thanks for any assistance / advice you can provide.

Venus GX -> NMEA2000 / Signal K

I have an EasySolar 24/1600 that I'm looking to tie into my vessels sensor / monitoring network.

From reading this article it looks like the recommended approach has been to bridge both the VE.Bus connection from the internal MultiPlus and VE.Direct from the MPPT direct to N2K. In the comments section though there was talk of a CCGX -> NMEA integration. Is this still something on the horizon?

I'm assuming it will apply to the Venus GX too? If so, that would be a much neater integration (VE.Bus and VE.Direct -> Venus GX -> NMEA) as well as providing a couple of additional sensor inputs.

On a slightly related note, has there been any consideration for providing a direct Signal K interface from the Venus / CCGX?

Venus OS driver for Fronius Smart Meter

Updated with latest results on 17-Apr-2020

Situation

At home, I have three roofs (east, south and west) with 9.9 kWp PV feeding into a Fronius Symo 8.2-3-M. The setup has Fronius Smart Meter 63A-3.
In a few days I am adding a Multiplus-II 48/5000/70-50 and 2x Pylontech US2000 (4.4 kWh net) LiFePO battery.

Problem

I am running Venus OS on a Raspberry 3B+. It nicely shows the power fed in by the Symo, with all details.

Venus is not showing any data from the Fronius Smart Meter.

Vision

I would like to have the data from the Fronius Smart Meter available on the Venus.

My idea is that I need a driver for Venus OS, which gets the data from the Smart Meter via the http API that Fronius provides and passes that information onto dbus - where hopefully Venus treats the data as if it came from a meter that it knows.

Steps Forward

I searched for a solution to my problem on the internet.I thought that I can not be the first to have this issue. But I found no direct solution.

There are several projects that might be a good start for getting to a solution:

  • dbusdummyservice.py from velib_python
    A simple service on the dbus.
  • dbus-cgwacs
    Reads energy measuremens from Carlo Gavazzi Wired AC Sensors (hence cgwacs), and puts it on the D-Bus.

Both projects look like a good start for programming my own solution.

Python script emulating the Victron Grid meter

Using dbusdummyservice.py from velib_python as a basis, I wrote this script:

#!/usr/bin/env python

"""
Used https://github.com/victronenergy/velib_python/blob/master/dbusdummyservice.py as basis for this service.

if __name__ == "__main__":
  main()

The script registers itself on dbus as "com.victronenergy.grid" and publishes values as defined on Venus wiki - dbus - Grid meter .

Before I run the script, I have the following situation on the remote console, feeding 3.9 kW to the grid:

[image]

When I run the script, I see the following situation on the remote console, as if the AC Loads would consume 3.9 kW:

[image]

So, clearly, my script does something. But not what I wanted.

As the next step, I added three paths to the script: "/Ac/L1/Power", "/Ac/L2/Power" and "/Ac/L3/Power" and then it worked. So, the "/Ac/Power" was not enough for Venus to accept the data as valid- it needed power for all three phases separately.

Now the remote console shows:

[image]

Final thoughts

So, it is possible to use a Fronius Smart Meter and make Venus see it correctly.

I think this could be useful for other users as well, therefore it now can be found together with some documentation on GitHub: venus.dbus-fronius-smartmeter

BYD LVL 15.4 - High Battery Voltage Warning

Hi,

since 2 days i've connected new BYD LVL 15.4 (two units) to a single MP-II 48/5000 together with 2 MPPTs chargers. Installation and configuration went smootly, following the Victron provided docs. All components running the lastest SW and no connection problems exists. Since the initial full charge i saw Voltage Warnings from the BMU (and on the CCGX following) - the Battery voltage is displayed at 55.3V and thus slightly above the documented limit. I though that CCGX (venus) is dynamically controlling the DC voltage receiving the changing limits from the BMU ? Any other option to correct in order to avoid these warnings ?

Clear list of detected PV inverters in Venus OS, stop automatic scanning?

I had some issues setting up my PV inverter when my system was first installed, getting it to stay assigned to a static IP address. As such my Venus GX still remembers each IP address it was found on in the list of "Detected IP Addresses" under the PV Inverter tab. Is it possible to clear this list entirely and start from scratch?

[image]

Secondly, my Venus GX seems to like automatically scanning for PV inverters periodically, several times a day, every day it would seem. During this time, the PV inverter that was already added becomes unavailable, and the data stops being sent to the console. Is there a way to disable automatic scanning?

Alternator w/ WS500 and Victron Venus or Cerbo

I love the Victron Venus system and would love to upgrade to the Cerbo (if i can every get my hands on one). I'm currently in the process of upgrading our alternator on our yacht. For this we will use a WS500 regulator which has the ability to get data from the victron BMV shunt in order to control voltage and Amperage coming from the alternator.


My question: is there anyway to see only alternator output through a venus or cerbo device? I know that the WS500 has a CAN bus but i would be unsure how these two devices would communicate or if there would be any way to display that information. It would be very helpful to understand what all the charging systems are doing (solar, wind, alternators, etc) on a single screen.

I do believe the answer is, no, there is no way to do this but i figure i would ask before i close the door to the idea.

Set AC-In to "Phoenix" or "Inverter" in Venus OS

Hello,

normally my loads are small so I chose a medium size Multiplus due to the lower standby consumption. This is also the reason I don't want to use a bigger unit or parallel setup because this would give me a much more higher daily consumption.

Anyway there are a few high loads I hardly use. For these loads I want to put a Phoenix 3000 at the AC-in of the Multi so I can run the small unit 24/7 and the bigger one only when I need it. Doing this I still can use the same circuits.

Technically this is not a problem, I think. But what about the Venus device. I can only set "grid" or "generator" as far as I know but not "inverter". This would give me a muddled VRM as the energy comes from the battery. Can this probably somehow be added in future versions of the OS? Or isn't it possible at all.

Can both, a Phoenix AND a Multiplus even have a VE.Bus connetion to a Venus or is this only possible with VE.Can?

Venus OS showing DC power as negative while inverting

I recently put together a new system and as I've been testing and monitoring things, everything is working great but when I look at things in the Remote Console, the dc power seems to suggest its charging the batteries while inverting. I have tested dc connections and Im seeing a consistent 13.2 volts coming from the 24/12 converter, and all 12 volt motors and appliances are working great.


From the Remote Console, the animation seems to suggest that power is flowing from the DC Power into the battery and the values coming from DC are negative. I've attached an image with an example of what I'm seeing.

[image]


At the time of this screen shot, the system was disconnected from any power source except the batteries. There was originally a converter/charger but is unplugged from AC power.

I found this question https://community.victronenergy.com/questions/34619/hmmm-color-monitor-shows-negative-dc-draw.html and have read that the DC power is an approximation but I'm wondering if there is something that I am missing in my configuration that would help this number at least show as positive when inverting.

Help with strange Color Controller behaviour with MP2 and SMA

  • SMA 5000TL-21 solar inverter on AC-Out#1
  • Pylontech US3000 batteries
  • Color Controller

If I have to turn the SMA inverter off and then turn it back on later, the CC display looks like this (still) after 15 minutes from turning on the SMA Inverter:

You can see that the Solar inverter is working because it is exporting, however:

  • SMA inverter is not shown,
  • AC Loads are not registering (=0) despite being around 600W.


The SMA is remembered:

But does not appear on the device list:

This has happened a few times and it often takes hours before the display corrects itself.

I was running FW 2.51 on the CC but saw that 2.52 was available, so I installed that, but alas, still the same problem.


The CC and SMA are both on the same subnet and I can confirm that the SMA has obtained its IP address which is fixed by DHCP settings. I can confirm this by the SMA front panel.


Is this a known issue?

Generator Stop after Grid is available

Four MPPT Solar controllers with a total of 56 panels

Large Battery managed by internal BMS that communicates with Venus.


Venus configures:

ESS Configured

Generator Start when SOC is at 45%

Generator Stop when SOC is at 90%


Should buy from grid if it SOC falls under 50%,

Should charge Battery with solar


The problem: during the night time if the system gets to under SOC 45% because of grid failure, the system turns on the generator, if a few minutes later grid is available, it does not shutoff the generator. In my case an hour later I had plenty of sun to charge the battery. I have not been able to tell the system to prefer the use of grid over generator.

Venus OS MFD integration on Simrad makes the plotter unresponsive

I'm running the Venus OS v2.30~43 on my Venus GX connected to my local lan on my boat, I have one Simrad NSS12 Evo 2 and one Simrad NSS7 Evo 3 conntected to the same lan.

The Victron icon is displayed on both plotters and I can access the Victron UI.

But the Victron icon "flickers" a bit on both plotters like every 10:s second, like it re-connect to the Venus, the Venus integration also makes the plotters a bit unresponsive when navigating on the home page and in settings page, sometimes I press an icon on homepage and the sound of pressing the screen is sounded but nothing happens, I then press again and the plotter loads the selected feature.

If I disconnect the Venus from my lan and when the Victron icon disappear from the plotters home page, the plotters works as expected and are much more responsive when navigating in menus, settings etc.

But neither in this forum nor with Google could I find any information related to Victron Energy and EEBus. So I wonder if I'm actually the first to be interested in it. Or are there already any plans to support the EEBus protocol in Victron Energy products?

Cheers
Erik
