I have a 5 KVA x 3 Quattro system . The system just switched off with L1 oveload amd later on restart shows #10 time sync error. After manually switching off and on all three the system tries to restart but fails with a click repateadly . L1 phase Quattro shows only blinking bulk LED while Y and B show the matching LED for #10 time sync error .
All network cabling is ok .
The system does not switch on in charge-only mode also. Checked the battery fuses they seem to be fine .
What are the chances of Quattro failing - the system is 3 year old
