3x multiplus ve-bus 400V error

I have 3x multiplus 24/3000 connected in a master/slave config with VE-bus. Making 3-phase 400V. Out of 1 phase or 24V battery. Worked fine for years. Now I get error codes when switching from mains to battery: E4, E3, E1. Quite random. And obviously system fails

One (I think slave) unit makes a lot of rattling noise. Or sometimes a somewhat slower tick, tick tick (half a second interval)

Cleaning UTP connections or even replacing them helped me in the past, but not this time.

Is this a dead machine or is this fixable?

And if not fixable, can I replace 1 machine? Are 12-15 years old..

Hi @jazz

Best to contact a local Victron distributor. Devices that old are usually not repairable. But a distributor might be able to help you with a solution.
