Quattro 48V/8000 not detecting mains grid and will not cut-over to grid

whatsapp-image-2023-10-22-at-113014.jpegQuattro 48v/8000 all of a sudden after 4 years cannot detect the mains grid so is stuck on Inverting / Solar / Battery.

Multiple "relay clicks" appear to suggest it was trying to cut-over to mains supply but it has given up trying to do that.

Restart has not helped.

Disconnecting load and mains and then restart has not solved problem.

Local Victron agents in South Africa not responding - any advice on fix appreciated.

Problem diagnosed.

Incoming mains line had a fault in the line causing voltage to drop to 169V under load. The Quattro performed as designed and would drop the feed when the correct voltage was not detected.
