Voltage sense error

What ve device would cause that as it indicates 8/11
I have a lynx shunt, cerbo, batteries and 2 mppts, are all these classed as ve devices?

I tried disabling voltage senseing in the gui but it made no difference, so i ended up using VE config, and did a firmware update at the same time.
The inverter is now running the latest firmware.
It did however state “disable for diagnostic purposes” so i checked the box and rebooted the inverter, now the yellow lights have stopped flashing.
But im still concerned that there is a fault somewhere only now its being ignored.
Whats the next point of action i can try to isolate the ve device problem?

Oh so this could potentially be a fault within the MultiPlus-II? Thats concerning, as it would more than likely need returning for repairs, which would be extremely inconvenient being im running my entire property off grid with it.
Ill contact the seller tomorrow and see what they say.

Yeah, or maybe ill buy another unit, and then run them in parallel as i do hit overload occasionally

Guys… What are you talking here?

If the error indicated the “VE.Bus error” field is 8 and/or 11, then the option “VE.Bus error 8/11 report” is to describe the error.
See pictures below.

Do you have in the “VE.Bus error” field the value 8 or 11? If not, then you are OK.
Only if you see in the “VE.Bus error” field the value 8 or 11, then you go on the bottom of the page and use the REPORT option to see an error description.


I have the feeling that the OP thinks of something else.
I believe he thinks he has an 8/11 error.
See his previous posts mentioned below.


So what does the error 8/11 indicate as the fault?

Since disabling the v sense on the generator tab of rhe MultiPlus-II the error is gone, but it states to disable for maintenance purposes, so im not happy with this.
Ive contacted the seller, and waiting to hear back.

I found the cause of the problem.

I wanted to use K1 with a relay.

After wondering why it wasnt switching i came to realise i was looking at the connectors back to front and upside down, compared to the installation manual diagram.

I’m usually very good at wiring, but made the mistake of connecting the relay onto the voltage sense pins, which are on the opposite end.

So i have now corrected this and the v sense alarm is now no longer a thing.

Thanks all for your help in troubleshooting, and apologies if I wasted anyone’s time.

Hi @mfred868

Thanks for coming back to correct the record.

Although it’s a bit humbling to admit something was from an installation issue, it really does help others who might have the same issue investigate if their cause is the same.

I have edited out the self talk to make it clearer as the accepted solution.

I wondered if there was a way to pre-charge the input caps on the Multiplus series.

I used to work on a fairly large three phase inverter that had a push button on its control panel to pre-charge the input caps.

With the Victron stuff, I just bridge a 200 watt 120v light bulb across one of the (open) battery breakers to pre-charge the 24v bus on my system. (The MPPT controller also has some fairly large filter caps as well.)

Only takes a few seconds, and once the blinky lights start flashing on the MPPT controller, I close in the breaker and remove the light bulb.

Connecting the V-Sense connections to the busbars through a 2-5A fuse (both poles), does the trick. The main caps are charged through the internal resistors between the V-sense inputs and the B+/- connections. This does the precharge, also on other products with V-sense terminals separate from Battery terminals.
