We have a Few Installations that have 2 or more multiplus II's where we have the system work perfectly until the grid fails, at this point we get error 17 master failure.
We Have victrons rj45 cables cables between the Multipluses and colour control. They have been checked.
The wiring is all the same length.
We have updated the firmware to latest.
The fuses are fine.
The colour control has been replaced at one site, but it still happened.
Is there any other advise?
This has happened at multiple sites now with multipluses in parallel.
