Error: #1 Device switched off

Q&A and troubleshooting
, ,
1

Hi Community,

i have a 3-phase installation with 1x Quattro 15k per phase.
Ever since installation a few days ago I am getting frequent errors #1 Device Switched off.

The intervall between the errors is rather random. sometimes we can go a whole day without errors, sometimes we get 15-minute intervals.

In another thread here in the community someone had a similar problem, turns out it was a hardware fault.
( MP2 device switched off periodicaly )

  1. How can I troubleshoot this issue? Is there a more detailed logfile somewhere? All I see are the meager error messages in the GX device.
  2. In case it is a HW fault: How can I identify which one of the 3 Quattros is the defective device? the 3-phase system always switches off all 3 devices at the same time.

thanks,

Olli

The only way is to see which one switched off. It is usually the one not flashing the error code.
See the ve bus manual here

A troubleshooting step can be just switching their physical position in the set up then re assigning them to the new phases.
I say just but i know its a bunch of work.
It is not usually a hardware fault.

thanks for your help!

I am aware of the ve bus manual and I have already set up automatic alarm monitoring on VRM for this system.

So I should be getting info from VRM or GX (or the Quattro device itself?). But nothing yet, except for the screenshot I posted.

Situation is:

  • System is 800km away at a customer site, so I am of course not there to look at the system or the GX device when the error occurs
  • VRM logging does not show anything about the devices being wrong, especially nothing mentioned in the ve.bus manual like temp/overload etc

basically exactly the same situation as I have found in this old forum posting: "#1 device swiched off" please help - VictronEnergy

So now I am looking for more logfiles or anything that could lead me to the root cause of the problem, WITHOUT me driving 800km just to swap position of 2 Quattros. :slight_smile:

More Info:

  • Problem occuring rather often, see screenshot from VRM
  • Nothing in the logs
  • No temperature problems
  • System cannot be overloaded, all it does is constantly charge 25kW from a CHP to the batteries.
