180kva System - Unspecified system shutdown -

[Lasse123 (Lasse Myrén)]

Dear Community, We have installed a gridconnected 180kva system in Albania, consisting of 12 pcs. of quattro 15000Va (4 on each phase) System has been running with no problems for a week, then with no specific reason the system shuts own in the middle of the night with these errors. Do you have any suggestions why this is happening.

I have many years of experience with building Victron systems, and I am a fan of the brand compared to others. This is the first time building a system of this size.

Battery cables are all same length

Thank you all in advance

@Lasse123 Worth looking at the ripple numbers using the widget and detailed view. At a glance DC cable length and possibly guage which be my first concerns. You may want to consult with another Victron installer, off such large systems, to get a second opinion.

Take a look at the docs. There are troubleshooting steps. Seems most likely an issue with the communication cabling. Error 17: VE.Bus Error Codes [Victron Energy]

I think of spikes on the grid is the cause.

Maybe … Error 17: Phase master missing

But the system should protect the compound by throwing the grid, if it falls outside the bounduries?
