CCGX Not showing PV Production

We have a customer with the following installed:
1 x Victron MultiPlus II (48/3000/35-50-230V)

2 x Fronius 3kW Primos (1 on the input, one on the output)

7kWh of BYD batteries


Currently everything is working ok, except there is no pv production being recorded and displayed by any of the Victron devices.

Using the Remote Console I can see that the MultiPlus is aware of both of the inverters. The customer has a Solar.Web monitoring setup for the Fronius inverters, but can only monitor one of them, so the customer can't use Solar.Web to record production data.


All of the devices are connected to the customers wi-fi, though it is not the best signal strength at the inverters.

The customer used to have the PV Production showing on the CCGX, and in the past a reboot through the CCGX would get it to find the Fronius', though this isn't working anymore.

I have had the customer run through a full shutdown of the system and restart, but this hasn't changed anything either.

There hasn't been a firmware update installed since the customer had the ability to measure

Any help would be greatly appreciated.

BVM712 voltage inaccurate

Hello,

I have read through some threads discussing this, but am still not sure the best course of action. I have the BVM712 hooked up. Everything is hooked up correctly and seems to be working well, but the voltage is consistenly lower than the actual measured voltage at the battery. The only connection that could be faulty is the supplied cable with fuse that plugs into the shunt. I have checked it and it is fine. I measure at the point where the cable connects to the battery and get the proper measurement, but the BVM shows less voltage.

I read that one user subbed in a 1A fuse for the supplied 100A fuse and that corrected the problem, but this seems strange that Victron would supply something that gave a faulty reading when the whole point was it's accuracy.


Is this really the best route to try to solve this problem? What are other users doing to correct this?

BlueSmart IP67 on a VW T4 California

Hi,

I intend to replace my burned original charger in my VW T4 California (Westfalia 1994) with a Victron IP67.
On the Westfalia charger, there is a secondary ouput line (around 12v) that feed the electronic unit of the vehicle to display the plug symbol.
I wonder if I can use the optionnal Si output of the Victron to feed the unit... I think it's ok for the voltage, but what about the current intensity ? I would like to avoid burning the central unit...


If someone knows, thank you in advance !

Random grid tripping, but ACin 1 Voltage still present...

Hi all


I have a very odd issue which has happened maybe 2 or 3 times in the last 4 months, today was the last.

What it looks like is the grid falls away for 0.15-0.3 seconds, when I review the data I can see the current going to zero but not the voltage. See the image below.

I can only assume the system is acting as it should, and that either the dip is just too small/ too quick to be picked up by the Quattro's monitoring, or the voltage sensitivity is set too high. South Africa is known for many things, one of them being an unreliable network, so I wouldn't be surprised if it was a voltage dip.


So I guess first and foremost has anyone else experienced anything similar?

And secondly, is there any way to verify exactly why the system started inverting?/ to what extent did the voltage dip?

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!

3rd party external antenna for GSM GX

Hey everyone.

We are about to install many systems in remote places in Africa and will use the GSM GX module for internet connection. Since a lot of the places will have poor connectivity, I am looking at improving the signal with an external antenna.

However, the option offered by Victron (below pic) seems quite limited. The cable is only 0.25 meter long, you need a screw base to attach it somewhere and the gain is only 3 dBi...

Does anyone have experience using antennas from other manufacturers for that?

Will 3rd party antennas work if we make sure to get one with the same type of cable, connector and frequency ranges? Is there anything else to take into account?

How to connect BlueSolar MPPT + BMV + MPPT Control

Hello there!

Spend some time searching this community but couldn't find the answer, so hopefully there is someone out there who can help me with my setup.

I currently own a BlueSolar MPPT 75/15, which just charges a battery. I want to expand my setup with a BMV + temp. sensor so I can monitor my battery status. I also want to add a MPPT Control to monitor my solar charging status to see what they are actually generating. The question; how to connect/share the temp. sensor to the BMV and MPPT ?

If possible it would be great to have the ability to see historical data as well, perhaps I can connect my smartphone as well to see historical data?

Some ideas that came up; Lot's of VE.Direct to USB cables on a hub. Lot's of VE.Direct to Bluetooth dongles to create a smart bluetooth network. I prefer wired over wireless but could it be possible?

And for the bonus, I also have a Phoenix 12/500 with VE.Direct, can I bring this in the 'smart system' as well?

Victron SmartShunt - Calculating battery degradation

I just ordered the SmartShunt from Victron and will be installing it in a few days. The system I'm installing it on is one I inherited when I moved into my off-grid house. The Flooded Lead-Acid batteries are about 6-years old.

One thing I'm curious about is being able to understand the degradation of these batteries. In the Victron app I will enter the Ah (1020@c20) of my system. Once fully charged and sync'd with the BMV I'll be able to see projected Ah available, battery percent...etc.

The batteries are rated at 1020ah @ c20, but because they're 6+ years old they most likely don't have the same capacity. Is the monitoring app going to give me some kind of way to see that, or does it "learn" how much capacity is actually in the batteries by correlating Ah drawn and comparing it to current voltage?

Any insight appreciated. Thanks!

Phoenix Invert 48/5000 Bluetooth monitoring

Hi , Victron experts.


I would like to centralised the configuration, control and monitoring the installation with a computer or a smartphone.

- What I've understood :

For the SmartSolar charge controllers nothing is needed.

For the BMV700 the VE.Direct Bluetooth Smart dongle will be enough.


- The questions :

For the Phoenix Inverter with a VE.BUS which accessories should I used to get a Bluetooth communication ?


If it's not possible an Ethernet link to my router is possible.

Maybe with the Venus GX/ Gerbo GX but I don't think that they will fit with my installation. I guess that I need à product with 2 VE.BUS and 4 VE.DIRECT (3 MPPT an the BMV) ports but GX products only get 3 VE.DIRECT.

1 Digital Multi Control 200/200A GX

1 Cerbo GX + GX Touch 50

1 Battery Monitor BMV-712 Black Smart

4 Batteries Lead Carbon Battery 12v/160Ah connected in parallel as one service pack

2 Solar pannels 305W-24V

2 SmartSolar MPPT 100/30

2 Cyrix 12/24V-120 Intelligent Combiner to charge engine batteries from solar during winther


As an EE engineer, I appreciate the quantity and quality of technical documentation available. Nevertheless, the "networking" and communication between components is not very clear because of the multiple networks/protocols/links (VE.Direct, VE.Can, VE.Bus, Bluetooth, etc…).


1/ I would have these components connected as described in the Cerbo GX Manual (chapter 2.1. Overview of connections).

I assume this is correct?

Or any recent changes or better way?


2/ Battery temperature monitoring remains unclear with respect to my list of components despite some information I could read on this forum. I read that enabling Cerbo STS would have the Cerbo send the measured battery temperature to the Inverter/charger system as well as all connected Solar Chargers.

I need temperature monitoring:

  • when charging with Multiplus (harbor)
  • when charging with SmartSolar with the Multiplus turned on (mooring).
  • when charging with SmartSolar with the Multiplus turned off (mooring).

Does the Multiplus temperature sensor provide temperature data to the Cerbo and to the SmartSolar even when the Multiplus is turned off?

Or do I need to add a temperature sensor to the BMV-712?

Or do I need to add a VE.Bus Smart Dongle?


3/ If I do not add the VE.Bus Smart Dongle, can I still get the system monitoring data connecting the VictronConnect iPhone app to the SmartSolar via Bluetooth?

Set BMV alarm to monitor DC watts draining battery?

I've got a home setup as follows:

  • Generator/Solar PV panels
  • 24V Lead acid battery bank
  • Victron Phoenix Inverter exclusively for water pump
  • Victron Skylla-tg 24/50 charger (to charger batteries from genset)
  • Victron Inverter 3000 for house AC power
  • Venus GX
  • BMV-700 battery monitor

And this is the Remote Console view:

[image]

'DC Power' shows solar power coming in (-W) AND also shows the power going out for the water pump (+W from the Phoenix). This also registers negative Watts when the generator is charging through the Skylla-TG.

'AC Loads' shows the power being used in the house (from the 3000 inverter).

The problem I've got is that sometimes the Phoenix is left running (due to water leak or taps on). This can be seen as +1000W in the DC Power box above.

My question is: how do I monitor this high DC wattage, and can I set an alarm if this goes too high for too long? (In case of water leak).

Ignore "load" current on SmartSolar 75/15 to measure solar yield

I'm looking to evaluate the output of a solar setup using an SmartSolar MPPT 17/15. The setup currently uses a 12V lead acid battery with a DC fan on the "load" output. The SmartSolar is set to turn the fan on at a high battery voltage threshold, and turn it off when a low threshold is reached.

This ideally means the solar panels are always being driven in MPPT mode, allowing recording of max power throughout the day.

However, when monitoring this system in VRM the periods when the fan is running show a negative solar yield - with mention of "battery watts" I assume yield is being taken from the current flowing in/out of the battery.

The "Solar Charger PV Voltage and Current" widget appears to have the correct data as both readings remain positive, but is there anyway to translate this graph into PV power output and graph it?
