Alternator Visual Input GX device. DVCC compensation for alternator charge.

Hi, I am looking for a very visual input for the alternator power source,

I am considering buying an Orion smart charger for the alternator, to have everything compensated and properly measured, but to my surprise DVCC can't include the alternator charge, neither with the "smart" charger that I thought was meant for this use.

Also, In my case, I share the boat with my father (67 y/o) and my brother, and they don't have that big technical knowledge, would be great to be able to see the alternator charge as another "device" in the bubbles graphs, to be easier to see at a glance the alternator charge.

Same applies for VRM Portal.


Victorn has gone very far to make this great products that we love, and can't leave it there, It's just a very little step in the natural direction to integrate this and make the perfect combo.

Venus doesn't see multiplus

I just purchased.a multiplus 12/3000 120v. I connected it to my Venus GX with a standard Cat5e RJ45 cable. The Venus doesn't see the multiplus. I've tried two different RJ45 cables. I've tried rebooting the Venus multiple times. I've tried turning the multiplus off and on either before or after the Venus restarts. I made sure I was plugged into one of the ve.bus ports on the Venus . The Venus is running 2.58 firmware and the processor firmware code on the multiplus is 2702430.VFD. I believe ve.bus should work correctly.

My multiples also makes a buzzing noise when it is in inverter mode. I assume this is normal, but wasn't sure if it was somehow related.

I removed all other ve.direct devices but that didn't help either. I have an MPPT device and a BMV712 that connect just fine.

Any ideas? Is it possible the ve.bus interface on the Venus or multiplus is defective?

Thanks in advance!

PV Inverter on AC-Out, connected but not showing up/no AC Load total shown

Solar Edge PV inverter connected to the AC-Output side of my split-phase+parallel Multiplus installation. Monitoring is working, you can see the device pushing updates every couple seconds:

But the AC Loads totals are obviously incorrect, and the inverter is nowhere to be found... There is about 2000W draw on the Loads side:

I've tried rebooting my PV inverter, and VenusGX several times, tried to rediscover the inverter but couldn't really find a way to remove it - or my old inverter. Is it time to reset the VenusGX and start fresh or something like that?

Use Victron and MQTT ?

Hi,

I just figured out that my Venus is providing any kind of MQTT support - thats fascinating andI would really like to use it ! :)

But there are some questions:

I have actived the MQTT support - so my Venus becomes a MQTT broker.

- All I get is a N/...../system/0/Serial message ... once ... no further updates, no further information ... is that all ?

- Can I use another MQTT broker (I already have one in my LAN) ?

- Is there a documenation about values and functionalities supported by my Venus MQTT ?

Venus GX - Modbus TCP - incorrect values for "User yield"?

Hi

I am connecting via Modbus TCP to a local Venus GX.
Everything works fine except for the readout value of Register 790 - "User Yield"

The "Victron Connect" app shows the CORRECT values and the readout works as expected
BUT the
2nd MPPT charger connected to VE.Direct 2 port. show different value.

According to the "CCGX-Modbus-TCP-register-list.xlsx"

Unit ID /DeviceInstance Remark
245 258 CCGX VE.Direct 2 port, Venus GX VE.Direct 1 port (ttyO2)
243 260 Venus GX VE.Direct 2 port (ttyO4)


I compared the readout via QMod Master and here are the results .
the first charger shows the correct value via Modbus:

[image]

The 2nd one shows different values:

[image]

According to the register list:

Address Type Scalefactor Range
790 uint16
10 0 to 6533.6

The readout value is at least 1 digit to short!
The value should have been ~ 72670 or so

This is not critical
but I was wondering if this is just a "small bug" in the
ModBus TCP mapping on the "Venus GX" ?

As far as I can tell, all the other values seem to give the correct values!

Can anyone confirm this behavior or am I wrong here?

Best regards

Grid Failure alarm does not reset properly after grid restoration

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 .

CANBus interface on GX
I have mainly a Victron system installed in a 5th Wheel RV; 1020W of Solar panels thru a 105V/100A MPPT solar controller, and a 12V/3000W/120A Inverter/Charger for shore side charging with a Bluetooth VE buss smart dongle. I installed it myself and used a MK2-USB to set up the Mulitiplus for the 500 Amps of AGM batteries I have. I also have a BMV-712 to monitor the system. I'm interested in upgrading to Lithium batteries and also adding one of the GX devices to be able to remotely monitor my system (I currently only use bluetooth locally).

I'm looking at Lithionics batteries, their internal BMS models have an output cable that supports RVIA RV-C and CANbus information, specifically it provides battery Voltage and Current data, battery Temperature and SOC data, remaining Ah capacity, desired charger state and charge specs, HVC and LVC status, total Ah capacity and current Power, accepts ON/OFF/Charge-ON commands and a few others. The link for the information specifications and protocols is here.

I've tried asking and looking around, but can't find anyone with answers. I would like to know if any of the Victron Venus GX or Color Control GX or Cerbo GX interfaces can accept this data from the Lithionics GTX12V315A batteries internal BMS using the CANBus data interface. And if all I would need is the Lithionics cable (75-H1FCR-CS2 Ampseal 8 Harness Kit), to plug into one of the GX's.


Also, is specific programming required for the GX?

Case Study – Remote Monitoring Like Never Before

As a WISP (Wireless Internet Service Provider), the ability to remotely monitor everything at our remote sites is absolutely critical. Network uptime is always at the forefront of everyone’s mind in the industry, and we will do whatever it takes to ensure that all of our sites remain stable and online from network infrastructure through to power systems.

WISPs probably have the greatest diversity when it comes to telecommunications carriers. Being a WISP, our power systems range from small solar sites only drawing 10’s of Watts right up to larger sites drawing hundreds of Watts (this is a 24/7 power requirement), to grid power, generator backup, and even wind power. Furthermore, here in New Zealand, we’re known not only to have harsh environmental conditions (probably the worst UV radiation in the world, salt spray in many areas, strong winds and heavy rain – and also snow in the Southern areas), but we are also at the forefront of infrastructure engineering when it comes to telecommunications.

I’ve been in my line of work for several years now, and I’ve certainly seen a lot. It only takes a couple of Saturday night callouts before you realise the necessity of protecting your outdoor cabling and infrastructure – but what about inside the cabinet? We’ve been affected by all sorts of wildlife big and small – from cows chewing unprotected cables, right down to tiny ants making nests inside electronics and ultimately causing premature failure.

So how do we monitor that everything is online and stable? Well, this has been the question that’s been plaguing me since day one. I couldn’t count how many times I’ve posted on various forums and Facebook groups asking about remote monitoring for sites, and the answers always come back the same – some over complicated system with an Arduino or Raspberry Pi that doesn’t quite do what we want it to.

We’ve tried all sorts of solar charge controllers and have never quite had the results we’ve wanted in terms of remote monitoring. Believe it or not, the best way we could find to monitor Lithium battery levels at one of our critical solar sites was with an IP camera pointing at a battery computer screen!


[image]


This solution, along with various DC voltage monitors etc is what we’ve used to “get by”. But it’s been less than ideal. For instance, in bad weather conditions the system above relies on our staff periodically logging in to the camera to check the battery levels! To add to this, we’d never found a one-stop-shop solution – no single portal to monitor ALL of our sites from the office (or as we call it, a NOC – Network Operation Centre) or even smart phone.

We’ve recently secured a regional contract to build over 100 new transmitter sites to deliver internet services to rural communities in NZ. For our small country, that’s fairly substantial. But as they say, with great power comes great responsibility – no matter what, we HAD to find a solution to our power monitoring requirements.

Then finally, in walks Victron – our knight in shining armour (almost).

As part of our contract, we opened our doors to various suppliers to tender for contracts for different parts of our build – from civil work, to radio supply, and of course power delivery. A local company (conveniently located just up the road from our NOC) introduced me to the Victron product range. At first impression, I was hesitant. I’d been here before; some product that doesn’t quite do what I want it to. But regardless, I ordered in some products and got them on the bench for some R&D.

The heart of our requirements turned out to be the Venus GX. Similar to the Colour Control GX (but without the touch screen that would serve no purpose for us), the Venus GX is a little device that interfaces many Victron products to the internet to be displayed on the VRM portal. But what’s more, the GX product range (which has been substantially growing in the last 6 months or so) also has a great feature called DVCC (Distributed Voltage and Current Control) which allows all of the devices connected to the GX device to talk to each other! This in turn, allows sharing of battery BMS, temperature sensors, even telling a grid charger to dial back its current when a parallel solar charge controller is getting lots of sun. This blew me away!

But aside from the Venus GX, the other device that really takes the cake is the BMV-700. Somewhat very similar to the battery computer in the previous photo as shown by our IP camera, the BMV-700 offers one key feature I’ve been asking for – a digital interface to other devices. And that’s just it – when paired with the Venus GX (or any GX device), we can now remotely view our batteries’ SoC (State of Charge) in the VRM portal. And it can even email us when the SoC drops below a predefined percentage!

While we’re only at the early stages of our build, we’ve probably deployed about 10 GX devices to the field – and I’ve been very impressed with the results. Most of our sites also feature a BMV-700 too, however for some of the larger sites we’ve opted to use Pylontech Lithium batteries (which conveniently have official support with Victron) which have a built in BMS which pretty well does the same as a BMV-700.

To add to that, the BlueSolar charge controllers that we’re now deploying (and a small handful of mains chargers) also have a VE.Direct port which can plug into the Venus GX, allowing us to graph and view how many kWh our panels are producing in real time.

So far, I’ve harped on about the great and amazing things that Victron can do for us. But what about the bad things? Well, there is one thing that I wish Victron would catch on to (please Victron, are you reading this?), and that is rackmountable devices. That’s right, not everyone using Victron products is trying to tuck them into the back of an RV or motorhome.

I’d say that around 80% of our sites have (or will have) 19” rack mount enclosures – which is very standard for the telco industry. So far, I’ve had to suck it up and bolt down chargers and charge controllers onto rack shelves. This might not sound like such a big issue, but for one it takes time to mount (remember, we’re talking about close to 100 sites with rack enclosures), but also each large device takes up to about 4-5 RU (1 RU = 44mm), whereas I feel this could be consolidated into 1-2 RU. Space efficiency is important in our industry.

So, while I feel they’re great for the WISP/telco industry, many carriers may overlook Victron products because they look like “consumer-grade stuff” as they are not easily rack mountable. In my opinion, I feel that if some of the larger products such as solar charge controllers, inverter chargers, the higher power end of Orion DC-DC converters (also very handy products!) and the Venus GX devices were available in a 19” rackmount format, this would open up Victron products to a whole world of telco industries that otherwise may have overlooked their product range. Remember, WISPs are very “hands on” and will do whatever it takes to get the job done – whereas some of the larger telcos tend to stick to more of an “industry standard” approach.

So now, we finally have a simple but very comprehensive solution to remotely monitor all aspects of the power system at each one of our sites – and all from a very handy web portal (there is also an app for smart phones). I can be anywhere in the world, and in a matter of seconds can view the power status of all of our sites. You can even sort the list by order of battery SoC or battery voltage.

The Victron product range when coupled to a GX device has been an absolute game changer for us, and now I can spend more of my Saturday evenings enjoying my social life rather than thinking about the status of my network. Thank you Victron!

Why Pylontech Batteries only reach 97% SOC

After the upgrade of Venus GX to v2.20 software, everything worked fine. The daily usage pattern is largely the same when I noticed Pylontech batteries (4xUS2000B) only reach 97% SOC (originally 100%) with plenty PV capacity available. Matthijs kindly advised that the end/of/charge voltage was lowered to fix an occasional over voltage shutdown from the Pylons and they are discussing various things with Pylon R&D though perhaps with some changes on both sides. Are there any planned changes envisaged or recommendations readily available? Charger is a SmartSolar MPPT 250/100.

Enabling solenoid valve with Venus GX and excess PV power

Hi,


I have a Venus GX and would like to utilize relay 1 to enable a solenoid valve to turn on my well pump at times when I am generating too much energy with my PV array:

https://www.hunterindustries.com/en-metric/irrigation-product/valves/1-pgv-pgv-jar-top

I have set the relay parameters to open when the AC consumption of my Multiplus II is less than 50W for 5 minutes continuously (i.e. when you know that it is a sunny day and my batteries are full).

I have been running these settings for a few days now and it changes the relay at the correct time. When I connect the solenoid to the relay however it does not energise the solenoid. I am already using a number of these solenoids elsewhere and I know that the continuous current to keep them energised is around 300mA at 24VAC. I assume that this relay should be able to cope with these types of solenoids?

On the Venus GX no energymeter is available.

No difference wheter or not I use a terminator or not.

Should the venus not be using the temp sensor to change the inverter charge voltage?
