Used Victron Cerbo GX replaces dead Raspi and why I lean towards no BMS communication!

Last night, the Raspi with Venus OS died! Initially, a faulty SD-card seemed to be the problem but after more testing, I could not get the Raspi to boot from anything, neither Venus OS nor RaspiOS. I also tried a brand new Pi 4 but could not get it to work either...
As this all happened pretty much in the middle of the night, I decided to use the Victron Cerbo GX from the S.P.A.T. Calibration Centre. But this device is already linked to this specific VRM. So, how can I re-use it in another installation? Thankfully, Victron made this task very easy.
I also highlight some feature of NOT having a communication between battery and inverter which, in my case, prevented a system shutdown. I really like the idea of having a communication between the BMS and inverter but with all the trouble we had in the last months, I cannot see this working.
And yes, there is once again a new JK BMS just around the corner...

[@MrElciupacabra]

finally!!! you arrived at the most logical conclusion that we don't need communication with the BMS. thank you!

[@urbanbeeman5402]

Lol as a subscriber for years, I must say.I have never hooked up my inverter to my BMS. My system is not nearly as large as yours and as far as Rasberry pie goes the seeds get stuck between my teeth. But I love your testing and there is usually some kernal of knowledge I can walk away with...Keep up the good work

[@007silverwings]

I'd recommend a SSD for the raspi, the SD cards are not designed for constant access with reading and writing 👍🏻

[@Zirrad1]

There are higher performance, more tolerant, cards that are only slightly more expensive.

[@RFDarter]

VenosOS does not support a SSD

[@ellingolsen3194]

Or use a so called industrial SD-card. They cost more, but maybe you don't need 32GB. I use 8GB which is cheaper.

[@ua420]

I can double that. Been playing with SBC for long time. Only when setup NVME SSD on OrangePi5 I forgot what corrupt system disk is. Otherwise just always have spare backup SD card ready to be swapped.

[@NiueChannel]

The solution is SanDisk "Max endurance" series. (not "high endurance").

[@keyem4504]

Since I didn't trust the SD cards in a RasPi I bought a Multiplus II GX. And I agree on the communication. For me the BMS is a safety feature. I am fully happy with Multiplus and Smart Shunt taking care of charging and discharging. Just keep it simple.

[@albertweterings828]

Connect a monitor to your PI's hdmi, it will at least tell you something. Might be telling why it doesn't boot.

[@dredge999]

A word of advice. Many SD Cards are counterfeit. I would say 50% on amazon are fake. We only buy SD cards directly from Samsung (and that's our card of choice for longevity and performance).

[@louwrentius]

Me too .... ( Raspi3 + 64GB Sandisk )

[@junkerzn7312]

I'm trying to come up with scenarios where the card could break like that. Its never happened to me, ever. I can think of two. One, the card got damaged from a bit of bendy bendy while you were inserting it and finally failed. Or, two, the card is held in place with a spring mechanism of sorts... heat combined with time could have made the plastic bendy enough that the stress broke it. -Matt

Hi Andy, be aware that there are a few cerbo GX devices with a hardware issue. Victron does have a manual how to fix this. You need to add a capacitor over the power supply to solve this. Maybe good to check for everybody with a cerbo gx. Cheers! 🍻

2 Battery Banks, 2 Victron Smart Shunts, 2 Raspberry P1 B4, 64 GB Sandisk cards, both running Solar Assistant. That gives me all the info I need locally, or like this year so far, sitting in Alice Springs, Brisbane, Cairns or Adelaide. My recommendation would to get the original Raspberry Pi power supply and also hook it up to a monitor, so you can see what's happening. You can also backup and upload your historical data without taking the SD cards out. Argon case with a fan hat too, good cooling.

[@alsemi-back-up579]

Hi Andy I bought a Raspi 4 and had to return it cause it was defective they sent me another one working Great with New version! Amazon sells some defective products sometimes but no hassle to refund you 99% of the time! Wait till your Cerbo Crashes like I hear they DO!!! Good Luck!

[@pondandmore873]

Moin Andy. Thanks for the video. It's nice that the system has continued to work. Even with this glitch. I don't know much about Ardiuno. but the cerbo gx works fine here with plenty of information. prost. Ein schönes Wochenende wünsche ich ihnen

[@chrisr819]

Fully agree. I have an ElectrodacusBMS with no communication to the Cerbo but communication to home assist. The BMV 712 is connected via BT to solar and inverters like Andy has it. The BMV is also last line of defense in case BMS fails and steers with its relay output a full shutdown is battery is below 9.9V and above 14.75V. Cerbo and also home assistant does monitoring, load optimization and home automation but BMS is completely independent the

I would recommend a SD endurance card. Those are designed for high writing cycles. Usually used in DVR and servers. On the other side, try to remove ALL partitions in your current SD card before using "Raspi Imager". It has an option for that (Erase -> Format card) in the drop down menu for operating systems.

[@notathome13]

Plenty of better options available than another closed source hardware. As a number of others have pointed out, backup your os and replace sd card regularly.

[@OffGridGarageAustralia]

A manual process is not practical.

[@fldutch]

Weird. Ok, Micro-SD cards do fail - quite normal. Never have seen one splitting in halves ^^. So on the 32GB limit: i run my RPI 4 with a 128GB Sandisk Max Endurance Micro SD Card with enhanced read/write cycles for video survaillance - knock on wood - works flawlessly with my InfluxDB/Grafana monitoring datagrave. On the RPI4 and VenusOS: i assume you made sure, that you used the VenusOS build for RPI4 / RPI5? With the standard RPI2/3 build the RPI4 won't start - done that, been there :).

[@stefanlevedag8072]

Hi Andy, stepped away from raspis completely due to so many failures. Mainly SD card but also power supply, the number one point of errors - check this out, may be the single point of failure you are looking for!. Replaced them with cheap used Fujitsu Futro - SSD and external power supply, runs forever...

[@millzee60]

Does VenusOS run on the Futro?

[@InspectorGadget2014]

SD card problems with a Raspi is often due to either powersupply problems or bad quality of the SD card. Powersupply-problems such as thin wiring, bad grounds, or a bad DC-to-DC converter on the Raspi, or even a brown-out. It is also recommended not to pull the power from the Raspi, but instead use the poweroff command instead. A broken SD card could indicate a DC-to-DC convertor problem on the Raspi, as SD Card uses 3.3 volts, and most of the rest of the Raspi uses 5 volts. When the DC-to-DC convertor fails, it could potentially blow-up the SD-card. The fact your Raspi no longer seems to operate could be indicative that indeed the DC-to-DC (often the blue LM2576 SMPS, a 3 amp switching powerregulartor) failed and inadvertently put more then the 3.3 volts onto your SD card, blowing it up, literally. I would recommend to use a good quality SD card bought from a (local) reputable source, preferable a brand-version (Samsung, Sandisk, Lexar, just to name a few) As for monitoring, whilst it is nice to have the overview & control, I rely on the BMS to do the work, the alarms etc, and, knock on wood, in the many years I have done my DYI LiFePO4's, never failed me so far. I like the App, I like the BMS. Everything else is a nice bonus but not a requirement to me.

[@MMMM2MMMM2MMMM]

So conclusion is: The raspberry has poorly build quality?

[@InspectorGadget2014]

@@MMMM2MMMM2MMMM No, I would dare to proclaim that. There are however some liberal design choices made with Raspi, that can at times bite you in the behind. E.g. the aforementioned DC-to-DC convertor is not grounded, which is not a recommended design-practice. One can also argue that the Raspi requires heatsinks but often lacks there off. And as already mentioned, the SD card is fine for storing the OS, programmes but for data, you should use a SSD, which is way, way more durable. So, poor build quality? No, but I would say it is an open platform where next to the various software, you should also take good care of the electronics (too); heatsinks, powersupply, storage. It is all densely packed together, for casual use it is often fine. But in applications such as outlined (and was in use) by Andy, you will also need to take care of the Raspi itself. A pretty box is just not enough. Those are my recommendations with almost a lifetime of experiences in electronics..

[@danarawding5198]

I have a script that I wrote that backups the important VenusOS directories and sends them to my network attached storage box. It runs as a cronjob every night. I've used it a couple times now. Should probably make a GitHub project for it.

[@OffGridGarageAustralia]

That sounds interesting. Yes, Github please so I can show it on the channel.

[@junkerzn7312]

Its just running Linux, presumably, you once you get an RPi working you can ssh into the RPi from a laptop and poke around. If you've never used ssh before then its worth reading up on setting it up and learning how to use shells (bash, tcsh, etc). A bit of a learning curve if you have only used GUIs before, though. You can also shut the RPI down and make an exact image backup of the SDCard, but sometimes linux boot code references devices by the serial number so it would require some messing around to get the image copy to boot. Personally speaking I always setup my RPis so I can ssh into them as root from another machine, and I'll usually setup rsync that I run from cron to maintain a backup of the entire image to another machine... at the very least, the configuration files, but its easiest to just backup everything. I can't really provide instructions, this gets into the weeds of learning how to use unix shells and applications. -Matt

[@OffGridGarageAustralia]

I can install the scripts I need to run on the Cerbo/Pi, but certainly not someone who can poke around and make sense out of it.

[@johnbrisbin3626]

I have broken pi sdcards by failing to remove them when putting the pi in its case (they stick out) you can, of course, put them back in once it is installed in the case. When you switch out boards and they all fail, look to the power supply (cable and USB adapter) and anything else that is common.

[@joesmith1142]

enrolling in lip reading school as we speak!!!

[@FarmGeluk]

You do have the option to setup a Solid State Drive to boot the R-Pi from. This should resolve the SD card issue.

[@retrozmachine1189]

Still a good idea to copy the running config to another media or cloud backup. To another media could be easily automated with rsync using the output of date (say +%w) to place each copy into a separate directory and rotate through those directories automatically. Run nightly via cron / systemd or what ever, done.

[@Ale-or2gk]

Hi Andy connect a monitor to these raspi.... on the screen like a normal computer you can undestand at which point of boot they are stuck. without a monitor how can you troubleshooting the pi? newer version of raspi-os maybe don't run on the older pi (like 64bit version for example) and the new pi4... this devices can be setup also to run directly from a usb (pen or ssd drive... infinitely more reliable than a sdcard) it is possible the bootloader is setup to run a usb and it is just ignoring your sdcard. With an hdmi screen connected you are able to see whats is going on..... and yes for the Pi4 you need a microHDMI cable/adapter!

[@typxxilps]

2 raspberry pi not running, a brand new, I doubt that this is a raspberry Pi issue. I have bought 20 from 2 to 4 and all of those are running. The only one that suffered here and there were early pi zero . But I can not give you an advice except no SD card in a pi and get an SSD for pi. Best move ever cause since then I have no more issues with dead pi except in my lab or sandpit where I test things. And there these SD break ervery now and then and just by my impression I would say the rather more expensive brand SD cards from Samsung and Sandisk struggle a lot more. 50% of those are dead forever, and the other half can be formated and will reboot and run like before. I am still on 8 GB SAN DISK which I bought a dozen from cause those fitted my needs and the backup on a NAS and the restore is a lot faster than a giant 16 GB SD. But only for the sandpit and lab, not for productive work.

[@royag]

I think the rp3 is dead. The rp4 needs a very powerful power supply. The best is the original wall plug for rp4. It is 5v 3A. The 3a is out of specs for the most usb adapters. I use in my setup 128 ond I think also 256gb cards. Works well. I highly recommend to use an ssd. The rp4 with the newest board update it is plug and Play. Just use an sata to USB adapter.

[@DavidPrue]

The culprit is your SD Card writer, no doubt. Write the SD Card on a different machine/adapter and see.

[@OffGridGarageAustralia]

Hmm, has always worked with this adapter and computer. I also tried different software to write the images.

PNY SD cards are famous for failures. Pis in general have two big issues: Power supply, and SD card. There are reasons to use one, but honestly, in your application, there are reasons to use something else more. It's just not reliable enough.

[@rpsmith]

My primary Victron system consists of a 48V MP2, MPPT VE.Can 250/100, Ekrano GX and two EG4 indoor wallmount batteries. My GX device is communicating with the EG4 batteries but DVCC is set to "No BMS control" so the batteries are reporting everything to my Ekrano but the BMS is not in control. I'm mainly using the BMS as a battery monitor and controlling the charge parameters via the GX device and the MP2. You can put it in closed loop but I really don't like the way it acts when the BMS is in control of everything.

[@JrgenDurkeHansen]

I have lost at least 4 setups on rpi because of a faulty sd card. Those card are not designed to that kind of use. Last setup I lost was my HA test setup, so that wasn't so big a deal.

When needed, I can swap the SD card, upload the Node-RED flows, and have everything up and running again in just a few minutes. I have no idea why you keep using home assistant.

As flash storage = SD-Cards have limited amount of write cycles you should do the following things: 1) buy endurence cards for car-dash-cams - those survice much more write cycles 2) on linux enable „tmp fs“ for /var/log to minimize write cycles of 10 times per second log file entries by redirecting them to ram disk. Would help to automatically reboot once a week or every night 3) backup backup backup - so no need to sit hours and days every 2 years when the card crashes

It is important you backup your system regularly and use the correct memory card; using a larger memory card serve no purpose unless you like to through your money away. They are a pain in the butt, talking from experience. It seems you are going to need a new Pi for starters. Don't use any fancy enclosures; I know they look nice but a sure failed for poor cooling and a premature failure because of the extra heat factor. Remember back up regularly.

Would it be worth you showing how to achieve (if you get my point)? I guess there are still a lot of guys running the Pace.

I would like to reduce communication between my BMS and the Victron gear. But, when the Victron gear is throwing 40A into the battery the cell balancing can’t cope and some of the cells run away. With communication the BMS can tell the Victron gear to reduce charge current to a point it can cope while balancing. The RPi, you’ve already considered cloning the SD card. I don’t think the RPi stores any information so swapping the card for a cloned copy when things go wrong should be fine. My brother has an RPi controlled solar charge controller and he as a backup RPi and a preconfigured SD card. As for the RPi itself failing, have you tried turning it upside down? Maybe it doesn’t like being down under :)

[@OffGridGarageAustralia]

Well, in this case, you are masking the underlying problem of unbalanced cells in your system. Of course, slowing down while charging helps to mitigate the problem, but it does not solve it. Cloning the SD card is not really an option as I pointed out. I will just forget for months or altogether and it's a hassle to do it manually.

Boot on SSD is not as simple as SD card but it's fine. My actual Domoticz box run on RPI 4 with a 64GB SD card Kingston Canvas plus. Only change one time to increase memory from 32GB to 64GB.

[@davidpenfold]

Maybe the 32GB SD card is faulty? Seems unlikely, but possible. I tend to back up my SD cards after installing and setting up the operating system, but would still lose any subsequent data. I'm looking at using the SD card just for booting, and an SSD for the file system. They are so much more reliable (and can be a lot bigger).

[@KrisStaber]

jk bms does not have their firmwares on the website to download. you are the only place on the internet providing jkbms firmware. also weird no?

[@OffGridGarageAustralia]

I'm sharing what I'm getting from them. As I explained, I'm not confident that they will ever pull this off.

Hello. Please tell me if my 15kw lifepo4 battery that I will receive from china will work with my untested Anern max 10.2kw,wifi/rs385 hybrid inverter?

[@vaneay]

did you try to connect a hdmi monitor on the raspberry pi to see if it display an error message ?

[@Rinzler1215]

I'm not firm with Rasp... But I don' t think there is a problem with different devices at the same time. So I guess it has something to do with the SD-Cards as already mentioned. But I would go first with the hint -> Monitor to watch.

[@Omri.Collects]

I’ve heatsinks on my Raspberry Pi’s as well as a cooling fan on the case. My Pi’s stay under 34°C.

I do my Linux Backups with restic, but also veeam is very popular

[@alsemi-back-up579]

Version 3.50~20. For your INFO. No Issues on Raspi 4 from Amazon.

[@ai4px]

I ran home assistant on a PI and it kept failing. So I gave up. I also ran venus OS to tinker and it failed. So I'm not sure about raspi's.....

[@cordebakker5513]

Maybe you have to format the SSD to the required format?

[@garymiller7870]

I've run into this problem on an unrelated device that required a fat32 format only.

[@morning...morning]

Just curious, do you measure the temperature inside your battery case, is it ventilated? Heat is definitely the enemy of most electronics and RasPis are particularly sensitive.

[@xpatrikpvp]

yea communication is really not needed if the stystem and the bms are setup correctly. but it would be nice to have a option in venus os to use the bms as a "secondary" measurement device for example if some battery is unbalanced to slow down charging at the end

[@rpsmith]

That functionality already exists.

[@OffGridGarageAustralia]

That's what I have right now. The 'Peter Boards' are CAN connected and report to the Cerbo/Pi but are not in control.

[@pmacgowan]

What I would like it to see it to use the Tuya system to communicate all the data via wifi. So each device would just be a tuya enabled and you would use the tuya app. This would work globally, no Bluetooth no cables simple QED

[@upnorthandpersonal]

Set up an rsync from the Pi to a computer to automatically back-up config files, /data, scripts, etc.?

[@OffGridGarageAustralia]

No idea what that is...

[@Juergen_Miessmer]

​​@@OffGridGarageAustralia Time to get into the basics of linux, after running it on your Raspi for years ...😉

[@Bastler95m]

I can tell you that SanDisk SD-Cards are relatively reliable on the raspberrypi and they can take a lot of abuse. I'm running a RaspberryPi B+ with a 128GB microSD as a mini web-server

[@Bastler95m]

also on the RPI with the dead microSD, maybe the broken SD-Card shorted some of the MMC data lines of the SOC to 3.3V

[@thomasschwarzenberger8943]

Auch wenn hier nie jemand antwortet: what is actually the reason for that energy in sunny hot australia is relatively expensive? Is it the low density and expensive grid?

[@amilww]

I feel sorry about you. Could you please connect a display to Raspberry PI device? It may show error messages.

[@richardnieradko8165]

Can you use a blue tooth dongle, to check your system on your phone with Victron App

[@stephan.scharf]

Maybe a format problem? (FAT32, NTFS)

[@Dutch_off_grid_homesteading]

Heya, well that you get with a DIY you have to fix the problem wen 1 apperice and some times that means in the middel of the night lol.

[@spassantechnik]

Stare at a green LED on the PI instead of connecting an HDMI cable and see what happens on the monitor 😅

[@rdcabal]

Why do you run all that? All you need is a hybrid inverter like Deye, battery banks, offgrid inverters to charge EVs. Btw, why not connect every battery to your storage? When all batteries are in parallel, you need zero lan cables, hybrid inv works between 51,5 and 53,5V. It's that simple.

[@alanwood82]

My home assistant instance runs on a ssd on a Pi4.

[@rdflo6739]

I never thought that running aan os off a static storage device like an sd card was was s good idea, so I still had an old laptop harddisk, stuffed it in a harddisk holder with usb interface and am running a rpi with Home Assistant for quite a while now. Possibly that could be a decent option for your rpi?

[@millzee60]

If you run apps that do a lot of file I/O you can create a RAM drive on the RPi so it doesn’t hit the SD card. Of course if you lose power or reboot you will lose any data stored on the RAM drive. I set up a system where logging was done to the RAM drive and every so often the data was copied to the SD card.

[@vaneay]

did venus OS could be vitualized on proxmox for example ? you could perform snapshots and backups of the venus OS VM.

[@OffGridGarageAustralia]

Where does Proxmox run on though? There is even more to maintain and to backup then... That's the wrong direction, I think.

[@vaneay]

@@OffGridGarageAustralia proxmox run on practically anything (raspberry pi, x86, ...). Yes it is an overhead at the start, but in the long time it might be more reliable. And it support ssd drive on the raspberry pi.

[@olafschermann1592]

So you made 2x 16GB cards out of one 32GB card ;-)

[@thomasschwarzenberger8943]

SD cards have always been a point of failure.
