LoRaWAN, Bluetooth, Raspberry Pi

I am in country with limited product availablity. I ordered for a client two Victron systems. Two BlueSolar MPPT, Two SmartShunts and two LoRaWAN. I realize now I should have purchased SmartSolar MPPT and BVM-712. I promised the client Bluetooth and Internet connection for their hotel. My distributor doesn’t carry SmartSolar, Bluetooth dongle or BVM-712. They do however have a BVM-702 but, doesn’t solve the Bluetooth and limited VE.Direct. I hope that Raspberry Pi could solve this issue. Any suggestions?

Call MPPT 75/10 solar stats with Pi

Hi

Little bit of a noob but hoping someone can guide me or point me to an already existing page...


Currently using a Pi 4 which is powered by solar and running Raspbian OS with CCTV software (Nx Witness)...

what I'm wanting to know is, can I create a script that will allow the Pi to send a ping/call to the MPPT 75/10 (via USB) and in turn the MPPT fires back the battery, load and incoming solar stats....im then wanting to use these stats to monitor the remote units.

Our software doesn't work along side with the Venus images etc


Thanks Guys

Smartsolar not showing up in venus or vrm anymore

Hi!
I have the Venus Pi, Smart Shunt 500 and the Smartsolar MPPT 100/30. All updated to the latest firmware and connected with the Ve. Connect USB cable.

When I plugged the solar into the Venus I could see it. Later on it has disappered. I think it happened after reBoot or firmware update. The MPPT has not the solarpanels connected yet, but is connected in the battery side.

The Smart Shunt is working correct

Any clue?

PV_ Insel / Heizstab Regelstrategie / SPS Kommunikation

Moin,

seit drei Jahren läuft mein Halbinsel-Setup, basierend auf:

6kWp PV,

Multiplus 5000,

2x smart Solar 250/65

BMV702 und

ca. 30kWh OPsZ Batterie (Hoppecke)

sehr erfolgreich.

Ich habe Venus GX auf einem Raspberry Pi laufen und mein Monitoring hat nach anfänglichen SD-Karten Problemen nun seit über einem Jahr gut funktioniert.

Nun hat man ja immer neue Ideen und, mehr aus Lust an der Sache als auf Basis wirtschaftlicher Erwägungen, habe ich mir nun weitere 3,3 kWp auf einer Dachfläche installiert, die nach PV schreit.

Ich habe bereits vor einiger Zeit einen 48V DC- Heizstab (1500W in zwei Stufen je 750W) in meinen Pufferspeicher für Heizung und WW-Bereitung installiert. Direkter Anschluss an der Batterie über 2 Schütze. Hintergrund ist meine Pellets Heizung, die an warmen Sommertagen zur Brauchwassererwärmung läuft uns damit mein Wohnzimmer weiter aufheizt.

Da ich generell meine Heizungssteuerung auf SPS Basis neu aufsetzen möchte, möchte ich natürlich eine Regelstrategie für die Heizstäbe programmieren.

Ich wende mich an das Forum , da ich möglichst mit der einfachsten der vielen möglichen Lösungen starten kann.

Meine Bedürfnisse:

Datentransfer vom Raspberry Pi ( Venus ) oder den Einzelkomponentenauf die SPS ? (Siemens Logo oder S7, ich habe auch noch einen Wago 750 controller rumfliegen, aber ich würde lieber bei der Siemens Range bleiben.)

- Hier sind folgende Werte wichtig.

MPPT-State (Smart solar Charger)

Batterie Spannung (BMV)

ggf. Netzeinspeisung des Multiplus. Dies ist aktuell möglich, wenn die Anlage jedoch ohne Netzanschluss betrieben wird, ist das keine Option.

Grundsätzlich ist es interessant zu wissen, wann die Solarladeregler nicht alles aus den Modulen herausholen, was aktuell geht. Andererseits kann man auch den Batterie SOC nehmen und ein Zeitfenster festlegen, in dem theoretisch noch die Sonne scheinen könnte. Was ich nicht will ist der Betrieb der Heizstäbe aus der Batterie sondern lediglich (hauptsächlich) aus überschüssiger Solarenergie.


Die einfachste Regelung wäre eine Relaiskontakt am MPPT, der mir sagt, wann er mehr rausholen könnte. Dann könnte ich eine gewisse Zeitspanne für den Heizstab vorsehen. Wenn das Relais in der Zeit nicht abfällt, könnte ich die zweite Stufe auslösen und so lange laden, bis das Relais abfällt.

Gerne würde ich aber in Form eines kleinen Brain-Drain Eure Meinungen hören.


Beste grüße,

Mathis

Advice on my Solar Upgrade

Hi,

I am newbie solar nerd, currently living off-grid with non-victron 24V system 7x285Wp(3S,2S2P) panels, 8x100Ah gel batteries in serial-parallel+2x220 victron gel, but it is time to upgrade because I "need" it.

I have place for 15 panels on my roof, so I am planning to upgrade to 48V with two strings (each 7x 450Wp mono panels) with SmartSolar MPPT RS, MultiPlus II-5000, 6x Pylontech US3000C

My first question :
my usual hourly consumption is only 500Wh, so would be more cost effective to add a smaller inverter before the MultiPlusII just to save some watts ?And yes I need the 4000W for some of the machines, but just for a few hours in a week. So can I turn on the power by automatic request on the MPII? If yes , how to do it setting-wise.
Scenario 1 : I am using my usual 500Wh but I want to do the laundry which eats 3500W at the start, so I need the power of MP-I

Scenario 2 :My batteries are below the low limit e.g.30%, so I want MP-II to turn on to charge them.

My second question :
Is Cerbo needed if I want to read multiple tanks and other measurements or it can be done directly just with RPi via com port?

Can I have a 2nd VenusOS device in my setup show information from the 1st?

In my RV I am installing VenusOS on a Raspberry Pi 4 and that will go with my equipment. I have another RPI4 that will have a touch screen that I am thinking will also have VenusOS on it to view control the main devices as well as take input from my tanks. Is it possible to see the devices from the 1st RPI on the 2nd RPI GUI? If there are better options on the 2nd device that don't include installing VenusOS and not monitoring the tanks, I am open to that too.

I will have the following devices installed:

- MultiPlus 12/3000/120-50 120V

- Lynx Distributor

24h MPPT data not syncing with VRM - why?

I have a small solar remote off grid setup with a Victron 75/15 MPPT. While sun is limited in winter I have a DC timer hooked up for disabling the load during most of the day. To track battery voltage and solar yield, I have Venus OS on a RPi installed. While the RPi also consumes load, it is not connected permanently (so it is placed after the timer). This is no option. It would drain the battery. Same for 4G router, and some small DC equipement. I noticed that when the setup is ‘on’ I can see stats on VRM but that seems to only show data from within the on-time frame. Via VictronConnect I can also connect to Venus OS and the MPPT and within the MPPT environment I can see all 24h data. Do you know why this is not synchronized with VRM?

Or is there an option to do so? Hope someone can help!

Connecting old Non VE.Bus Phoenix Multiplus 24/3000/70 to CCGX (or Raspberry pi running Venus)

hello and good morning,


my first Q on this forum!

have a system with a BMV700, a MPPT 100/30, 600W solar and 4XT105RE Τrojans and a 8KW diesel generator all working fine on a motorboat (there's also an alternator as well charging via Sterling advanced regulator).

Last season I replaced my Phoenix charger with a s/h Phoenix Multiplus 24/3000/70 with a firmware 14XXXX (will confirm that later on today and post a pic) and a single RJ45 socket on the PCB saying control (on it's lefthand side)

Anyway, my local installer helped me with a MK2-USB (as it turns out!) and VEConfig to set it up. All working fine, no issues.


Now, bought and setup a Raspberry pi 3B+ and 2 VE.Direct-USB cables, hooked them all up, setup my VRM Portal account and all's fine.

Having forgotten that he'd used a MK2-USB cable and having gone through all the literature on your site, I wrongly assumed I had a newer version VE.Bus compatible Multi and bought a MK3-USB cable wired it all up and unsurprisingly Venus doesn't read/know of the Multi :-(


So, after all this intro my simple Qs are:

A. is it possible to somehow connect this non VE.Bus Multi to Venus and get the proper functionality/reports?

B. what is the protocol used in this "control" RJ45 socket? any info/board/software that I could play with?

C. if there's no luck with A and B, is there any other (cheap) h/w I can add to the system to monitor AC consumption (well preferably generator in, system out)


I don't care about the remote control functionality, and using the boat installed home automation system I do turn off the multi when boat unoccupied for x hours, so I'm fine in this respect. What I want is monitoring AC usage only.

(I understand that the MK3-USB will either go to ebay or kept for my next Victron piece of h/w most likely a BMS for LiFePO4 in 2021 or 2022!)


cheers

Blue Sea 7603 Replacement - MultiPlus, Cyrix-ct, SmartShunt & RPi

Hi,


I’ve currently got a ‘Blue Sea 7603 - 10A BatteryLink Charger’ and an APC UPS. I purchased the Blue Sea because it can use AC shore power to charge two isolated battery banks with a 3 Stage 10A battery charger but also it can use DC power from the alternator to charge both the Start and the Auxiliary battery through an integrated 65A ACR (Automatic Charging Relay - Automatically combines batteries during charging, isolates batteries when discharging and when starting engines).


The problem with it though is that there is no monitoring or visibility of what's going on apart from a panel mount 'display' consisting of a couple of LEDs. I've recently had a problem with my Auxiliary battery not seeming to hold charge and I'm struggling to troubleshoot and having to use a multimeter, etc.


I recently learnt that the MultiPlus 12/500/20-16 has a second output intended for charging a starter battery albeit limited to 1A. Therefore would a MultiPlus and a Cyrix-ct be a suitable replacement for the Blue Sea and an APC UPS?


I've added a SmartShunt, VE.Direct to USB Interface (for the SmartShunt), MK3-USB (for VE.Bus on MultiPlus) and a Raspberry Pi with Venus OS to meet my requirement of greater monitoring and visibility of what's going on. However how will I know the status of the Cyrix-ct?


Is there a panel mount display which can interface to my configuration?


Thanks in advance for your advice.


Regards,

Paul.

Importing data on raspberry pi venus os

Hi

I want to monitor the water level in a well 10m away from the raspberry pi. Until now I had 2 reed water level sensors connected on the digital input pins on the pi.

Because the sensors are quite unreliable (the connection) and wanted better precision I have mounted an ultrasonic sensor in the well and with a small arduino I know the exact water height.

I need to monitor the water level because the well is not very deep, the refill rate is slow and I want to remotely start the irrigation system - I don't want to run the pump if not enough water.

I was thinking of converting the ultrasonic output into a voltage to be fed into an mcp3208 adc but surely there must be a better way than all that data conversion and more locations for errors to be introduced.

Maybe serial communication between arduino and pi? Maybe using an esp module to publish the data somewhere on the web and fetch it on the pi?

Is it even possible to display that data on the victron GUI? Do the tank level menus show up only after activating analog inputs?

Does anyone have a better or simpler way?

I know it's a very specific problem but I'm stuck and my only hope is this community.

Sadly my python skills are non existent but I always thought that with enough determination and Google anyone can achieve impressive goals.

Any help would be appreciated and thanks for reading

Victron MPPT connected to ICC Software communication problem

Good day

I am running ICC Monitoring Software on a Raspberry Pi, monitoring an Axpert Inverter, Victron SmartShunt via a VE Direct to USB cable. These monitoring works like clock work.

Yesterday evening, I have linked up a Victron Smart Solar MPPT 150/60 to my system and connected it up via a VE Direct to USB cable also to the Raspberry.

On ICC "Victron MPPT" is on, "Add Victron MPPT PV to Total PV" is On, "Use external Victron Battery Monitor" is On.

After restarting the Raspberry, ICC picked up the MPPT, showing the model, serial number, firmware version and battery voltage in the Victron MPPT tab. The battery data from the SmartShunt update correctly and around every second.

However it was dark and no PV data was shown. After the panels started to produce power today, I noticed that the ICC PV info updated very slowly and does not correspond with info shown on VictronConnect. The ICC Battery Voltage and MPPT Voltage update around +/- every 60 seconds incorrectly and the other values update like once or twice in the hour.

First, I thought the VE USB cable was faulty, swop the cables around between the SmartShunt and the MPPT and still no luck with the data feed from the MPPT to ICC. The SmartShunt updates correctly with any of the two cables.

On the MPPT, the TX port is set for Normal Communication and the RX Port is set for Remote On/Off, Smart Networking is enable between the MPPT and the SmartShunt.

Have spoken to ICC and he said that they have other clients with a same setup and on their systems both the MPPT and Battery values update fast and correctly and don't know what should the setting on the MPPT be.

Can someone assist me to get the MPPT data feed correctly?

Phoenix Inverter 12/1200 VE.Direct does not show AC out

I can read all the values that the datasheet says is available, like AC OUT Volts is what I expect at about 120.02v. But AC OUT Current (AC_OUT_I) just shows -1 or 0 for me.

I have some experience using VE.direct USB cable with a raspberry pi to read the metrics from the serial port for a BMV so I'm pretty sure I'm doing the basics right.

ESS drains battery after 100% SOC and 1Hr absorption is reached

When charging the battery to 100% with multiplus and mppt it finally reaches absorption point. After 1Hr of absorption it stops charging and starts to discharge the battery into the grid.

I tried different things to stop it from happening,

- update newest firware tot the multi,

- update mppt,

- even downgrade the venusOS to 2.22 instead of the 2.23 i was running.

- pull out the mppt cable(maybe it sends faulty values, but it wasnt)

- resetted all devices..


it keeps discharging battery to grid. I have no clue what to do next...for now i disconnect the mains to stop it. Anyone who has an idea?

So the VRM dashboard shows 'live' consumption at last update, the advanced widget 'System Overview - DC system' does a good job of allowing me to see watts used at any point in time.

Load out data from the MPPTs clearly exists. Why then is there no DC consumption logged on the dashboard like solar power produced?

Off-grid Multiplus II + SmartSolar MPPT system monitoring

Hello,

I'm planning an off-grid installation with four solar panels, a SmartSolar MPPT 100/20 (48V) and a MultiPlus II 48/3000/35-32.

I'm wondering how I could monitor my system and I see (at least) two options:


1) Raspberry py

In this case I'd need to get:

  • UTP cable + MK3-USB interface to connect MP II to the Raspy
  • VE.direct cable + VE.direct to USB interface to connect the MPPT to the Raspy

Is that right? Or can I connect the MPPT directly to the MP II? In the latter case I don't need to buy VE.direct to USB interface

2) MultiPlus-II GX 48/3000/35-32

In this case I'd need to get only:

  • VE.direct cable from MPPT to MP II GX.

Is that right? As MP II GX has only one VE.direct port, is there any other way to connect MPPTs to it, in case I will expand my system?

Do I really need MK3-USB interface with MP II GX? What's the purpose of USB port??


Which option do you suggest?

Sorry for the large amount of questions and thanks in advance for helping me to have clear ideas :-)
