Hi, We have a Off Grid instalation with 3 Quattro 48/10000, 1 Color Control GX, 3 BYD Box 13.8 and Fronius Symo 25.0
All works fine since October 2018, but this year we look's this message:
VE.Bus Error: VE.Bus Error 1: Device is switched off because one of the other phases in the system has switched off"
This happens tipically always in the morning , never at night. In less tan 1 minute the system is on again.
All Firmware was upgrade to last version since comisioning
We have changed all ve.bus wires
We have examinate all electrical variables in the vrm report, but we don't find any mistakes or overcurrent or shortcircuit that can justificate power off inverter.
At this moment we don't know how to resolve this problem.
Thank's in advance
