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!)

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


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.

SmartShunt with Temperature Sensor and Starter Battery Voltages?

Hi all,

I am using a SmartShunt 500a with a Victron temperature sensor for my battery in a motor home. Now I want to monitor the voltage of the starter battery, too.

Can I connect the SmartShunt to the starter battery in addition to the temperature sensor? If not, what do you recommend?

The temperature is provided via VE.network for a SmartSolar MPP 100/50 controller. Also both are connected via VE.direct USB cable to a Raspberry Pi with Venus OS and 7“ touch screen.

Importing data on raspberry pi venus os


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

"Create Access Point" option missing on Venus OS on Raspberry Pi


I have VenusGX for my offgrid system which works perfectly. I have since started reworking my Caravan to incorporate a Victron setup. I have setup a Raspberry Pi (Tried version 2 and version 3) as a VenusGX substitute. I however do not have the option to "Settings → Wi-Fi → Create access point".

I have seen one other thread on here that had no replies regarding this: https://community.victronenergy.com/questions/48565/access-point-option-missing-venus-os-raspberry-pi.html

Does anyone know why this option isn't available? Or if there is a config setting on the Pi I need to do. The Raspberry Pi 2 has a wifi dongle that does pick up other networks. Pi 3 I used the built in Wifi to connect to other networks.

Any assistance would be greatly appreciated.

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.

Example output, includes model and firmware if anyone is familiar with these:

['Checksum', '\xd2']
['PID', '0xA279']
['FW', '0114
['MODE', '2']
['CS', '9']
['AC_OUT_V', '12001']
['AC_OUT_I', '-1']
['V', '13541']
['AR', '0']
['WARN', '0']

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?

thanks in advance, Tommas




RaspberryPI with venus image (ESS-optimized w/ battery life, feed-in allowed, 35% min. SOC)


LiFePo4 25.6V 7kWh battery with 2-wire BMS

in the multi charger tab set the next values: (27.60V / 8cell = 3,45V/cell)



the curve is a little strange because of disconnecting the mains to stop it.

DC consumption not logging on VRM?

I have just set up a Raspberry Pi running Venus OS

System: 2x 75/15s + Pi / 7s Lithium NMC / DC only setup with all loads via the load outputs.

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


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 :-)

Older Phoenix inverter 24/2500 readout VenusOS

It's quite hard for me to find any clear information on the possibilities of my inverter.
I'd like to connect to this inverter and read out its stats and power usage.

I know all the recent models of this inverter/multiplus have ve.bus possibilities and I know my current one does have this phone/ethernet like port.

I'm now in the process of setting up VenusOS on a raspberry to read out the MPPT charge controller but can I also connect to this older inverter? It's a Phoenix Inverter without the orange stripes but with the red phoenix bird.

My guess is it can be done with the MK3-USB interface but I'd like to have a confirmation on this and if it's possible, what kind of information can I pull from the inverter? If not possible, any other ways to pull status information from this device?

Thanks in advance.

SmartSolar 75/15 SOC Calc Raspberry Pi

Good Evening Victron Community,

I have been running a tiny setup with a single SmartSolar 75/15 and a 65Ah Lead Acid battery for the past few days.

The latest addition to the setup was a RaspberryPi running VenusOS that connects to the SmartSolar 75/15.

Would it be possible in future releases to Calculate SOC of the battery (if given a Capacity in Ah) for systems where all loads pass through the MPPT load output and where all charging happens through the MPPT?

Additionally is there a way to remove the AC Input and Loads symbols for these DC only Systems?
