Can't see multiplus in VRM or cerbo

[fernanci]

My installation is 2 years old and I have 2 multiplus in parallel. Since 1 month ago half of the time or more I can’t see inverters in VRM or cerbo, the look “off”, this happen randomly but more or less half of the time everyday.

Try replacing the UTP cable between the inverters and the Cerbo.

I tried it, same results. I checked all cables before trying.For example, today some hours didn’t work, from 12 till 18, and now works perfectly
