One out of three daisy chained MPPT’s doesn’t show up

Hi everyone,

I have the problem, that one out of three daisy chained smart solar MPPT 250/85 doesn’t show up in the device list. All of them are connected to a Cerbo GX. The first time I connected them, this particular one was at the end of the daisy chain. Also the rotary switch was set to 5, which I set to 2 afterward.
Even if I put it in the middle of the chain, or just connect it by itself I doesn’t appear. I terminated the VE. Can on both sides.

Other than that, it works normally like the other ones. I just cannot see it in the VRM even though it feeds energy into the system.

Thanks for your help!

this is of course using ve can

does it read if you use the ve direct connection,

are all the settings in each unit set to a diferant canbus instance, you should not have two devices of the same type with the same instance

Thank you for your answer.

What do you mean by “a different Can Bus instance”?

How do I set the Can Bus instance?

I fixed the issue by disconnecting the Batterie and the solar panels. After I connected everything again it worked.
