question

Hi, please check the VE.Bus error codes documentation.

https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes

And make sure all firmware is up to date.

If those two things don’t help, follow official support procedures; as on our website.

I hope its sorted soon! Matthijs

Just a up date on this situation

I was able to reproduce what caused the error 17 to arise.

On both time that ve bus error 17 before it was when every thing in the installation was switched off other then the internet router with minimal load. When I now did the same, it went in to error 17 within 10mins

But everything works fine with loads and generator changing etc etc

Is there something in the ve configure relating to AES or search mode that needs to be set?

Regards

Mike

Have you tried inverting the master and the slave units

Hi

Think i need to clarify this running 2 48v 10kva Quattro’s in parrellel with byd b box pro in a off grid install.

AES and search mode WASN’T turned on or active when in the ve bus error 17 would arise.

It’s just gone in to error everytime it has little or not load

For example on every occasion it has errored it has had only a internet route on the inverters running

And when I simulated this it went in to error 17 within 10 mins

Even after a day of having a 1100watt water pump jet washer power tool batterys etc etc running on it with no problems at all

The one thing I did do after it went in to error after 10 mins is turn the AES on and selected search mode and had no problem for over 12 hours

The installation had been left with the AES off no search mode but a 120watt bar Heater and internet router on it and see what happens

Hi all

Just a update on the installation and the situation with the error 17 ve bus

On leaving the installation on Sunday mid day and a 125watt tube heater running on the inverters the error hasn’t occurred

Which on previous occasions after this length of time the error 17 ve bus would have appeared. With only the internet route drawing ac load off the inverters

The conclusion I have come to at the moment and have my fingers crossed the error doesn’t occur again is that the quattros or maybe the master with minuimal/ next to nothing load wise the internet router was drawing sort of sent in in to a standby/sleep mode (even with the AES mode disabled)

Hope this may be of some help

Ive just had the same error on one of my systems, very similar set up too, 2x 15kW quttros in parralell and BYD pro batteries was running fine and then just turned off for no reason last night with VE bus error 17 there was no strange behaviour to trigger it voltages where all good, battery temperature was fine at 20 degrees and around 70% full, there was a drop in load from 4kW to 1kW in the 15 minutes before the fail but thats nothing on what they are capable of doing, firmware on the quttros is 430 so will go to site and update them today. This is the second time the system has failed this week last time it was VE bus error 5 overvoltage on AC output which was very strange as the quattros output went from normal 230v upto around 270volts but stayed around there for 9 minutes before hitting 278 volts and failing, this was strange as the quttros had plenty of time to bring there voltage down but failed to do so, in this case there was 4kW of ac coulpled solar coming in from the fronius inverters and the genreator was off. Has it happened on yours again since Mike?

So the common factor here seems to be Parallel Multi's and BYD batteries..

Hi all, Error 17 is 99% of the time always pinned down to faulty cables or broken units.

Please replace the cables (if not already done); update firmware to latest (if not already done); if that doesn't help please follow the official route: ask the distributor to help which might lead to replacing the units.

@Boekel yes BYD + parallel multis seems the common factor I agree; but I don't see any relation.

Had no issues at all with the installation

Have had it running now for the longest period of time with out any error 17 message 7days plus

There are two things that are different from when I had it error

One the internet router AC to dc adaptor isn’t powered by the Quattro it’s powered direct from the byd’s now via a Orion dc to dc converter

And two there is a load on the inverter now all the time in the form of a 125watt green house heater

I personally think it was connected to the router

Have had some information given regarding AC-dc adaptors suggesting that the power correction and the regulation regarding the quality of them isn’t governored unlike ones above 70watts that have to comply with eu directives. The thinking is may be some harrmoic noise generated by these adaptor and causing the communication issue between the master and slave

Since this adapter for the internet route has been removed have had no problem. small load or the adaptor not being used ??????

Just like to add too

No cables changed no firmware change to fix the issue

Never had any doubt about the cables from the start

Just trying to give you as much information that I have experienced with the issue and what I believe had fixed it

Hi @mikeb is yours still going well? Mines just gone again on error 17, 2 days since the last time, Ive updated firmware of both quattros and changed which of the units is the master at the same time, i think your thought of noise from the router power supply interupting communication seems like a good idea im considering taking mine offline even though i dont really want to to see if this has any effect. Sounds like theres at least four other victron/byd installs suffering from this issue though

I am watching this thread with interest, I am sympathising with you both, and grateful that you are approaching this with a solutions oriented attitude.

I hope that you can both resolve this to reliable systems and we can learn something and either make a change to improve this for all users or at least have another troubleshooting step that might help them in the future.

Just a update On the system

All running fine

Happy to say ive been problem free for 8 days now too, i actually changed the ethernet cable after realising it was shielded, the colour control manual does state you shouldnt use a shielded cable for ethernet as its not isolated but that it wouldnt be a problem in 99% of installations i guess this configuration represents the 1%. I hope this is all it was for the other guy that was having the same issues on the other thread

I spoke to soon

Saw today it went in to ve bus error 17 after running fine for well over 2 weeks

Was able to turn the inverter on and off via the remote console on the vrm

Hi All,

I too have experienced the frustrating random Error 17.

To date, I believe I have it sorted (touch wood) and thought it was worth a mention.

System:

On-grid

3 x Multiplus 3KVA, single phase in parallel, 1 master and 2 slaves

8 x BYD 2.5KWh modules with CAN BMS

CCGX

1 x Victron 250/100 MPPT Charger

I found I did not have DVCC enabled on the CCGX and I also missed the correct settings for the dynamic cut-off values, all on 47Volts. I made both these changes at the same time so cannot say if it was one or the other or both, but happy days for now.

On the Venus-device, go to Settings, System setup:
