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...

[image]

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?


Thanks in advance and much sun to all!

Is it posible to set an alarm with two separate conditions

Hello everyone,

as my batteries already twice caused a low voltage alarm (although above 80% SOC) after some days with little sun, I would like to set an alarm for the voltage in combination to the current, i.e. "voltage < 24V while current < 10A". Anybody can think of a possibility to set such alarm or should I send a feature request to Victron?

Greetings from Colombia,

Monitor midpoint voltage and temperature with mppt 100/50

As far as I understand it is not possible to connect a SmartSense Temperature sensor and the BMV Battery Monitor. So: is there a way to monitor both with the Victor equipment?

Another question: I have 4 Batteries, two in series parallel with the other two (24V). Is there a way to monitor both mid-points?

Thanks!

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?


Many thanks in advance!

BMV-712 and Smart Monitor w/o MPPT Controller

I would like to add a battery monitor to my travel trailer, but it's not easy to get from the best place to mount the display to the battery. I would like to use a BMV-712 but instead of running a voltage sense wire (and temperature sensor) from the monitor to the battery outside the front of the trailer I was thinking of just using a smart senor, but all the information says it's used in conjunction with a smart MPPT controller. Is that **REQUIRED** or just typical?

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.


- The installation :

It's composed of 2 Phoenix inverter 48/5000 in parallel, 3 SmartSolar charge controllers 250/70 and 1 BMV700.


- 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.


Any suggestions are welcome.


Best Regards

VRM: More battery info (Cycle Count, avg. SoC)

Is there a chance the VRM could compute and show the "effective cycle count" of a battery in a shown timeframe - and/or total? Seeing this raw SoC is nice and informative, but in order to estimate % Lifetime left, there are some crucial infos missing.

[image]

A moving average SoC for the past 30/90/... days would also be helpful.

So showing something like:
300 Full Cycles eff.
85% SoC avg

would be helpful to observe aging of batteries at the monitored site.

Battery temperature monitoring and component connections

Hello,

I am planning a full Victron installation on a brand new 36 feet outboard motor boat with the following components to have the highest level of service electrical autonomy when mooring:

1 MultiPlus 12/3000/120-16

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?


Thanks for your help

Why is my solar regulator not feeding my battery

Hi all.


Right now then sun is shining and my MPPT is saying 22 V from my solar panel, my smart shunt is saying I am consuming ~4A. Voltage is 12,92, state of charge 98%. Now I am wondering why my MPPT isn't feeding my battery - it says 0W? I am below 13V and less than 100% state of charge. Why waste that solar energy?

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).

Thanks!

SmartShunt Settings

I just installed the Victron SmartShunt and am a bit confused on the exact variables it wants for the battery settings. I wish the settings page was more clear on what it's looking for. I also wish it could gather this data from my charge controller and they could sync instead of duplicating data in two places.


Battery capacity: I'm assuming this is @ c20?

TailCurrent: In the SmartSolar charge controller the tail current is 2Amps, however the SmartShunt is asking for a percentage. How do I calculate the percentage?

Peukert Exponent: I have Flooded LA Batteries however the manual doesn't reference a number

Current Threshold: I don't know how to calculate this

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?

Current Monitoring from multiple sources

Hi All

I have a sailing catamaran, so 2 motors and alternators in the aft, I also have 6 solar panels with 6 PWM controllers on them I want to change these controllers to 6 Victron smart controllers 75/15 ones. The alternators supply 2 start batteries one for each motor and the solar system charge the house bank of batteries (around 500 Ah), Version 1.47 firmware update allows these to solar controllers to synchronise so they dont turn each other off but it also says if you have a GX device connected you cant use this functionality. I was wanting o use smart shunt units on the alternators to monitor their charge current.

SO what I'm overall trying to do is get a GX unit like the CERBO to monitor the smart shunts, the 6 solar controllers and maybe another smart shunt for the supply to the inverter, its not a Victron inverter. Would love some advice, thanks all

With the latest update of the app (iOS and macOS), it no longer shows decimal values in the Trends graphs. e.g. Battery voltage is rounded up or down and only shows 12,13,14v etc. I'd prefer to see the decimal value to see movement in the values that are not so easily discernible in the graph line.

Is there any way to change that from settings?

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?
