Multiplus 24/2000/50 loud hum and flickering lights

System has worked well for 5 years in off grid setup. Symptom is a loud hum with rapid flickering of LED lighting. After switching all off worked again for a short period but reverted to loud hum. Finally the Multiplus shut down totally.

Much more information is needed.

but try the below

Downloading the Victron tool Kit, this will then tell you what the flashing lights mean

Suspect

Low battery voltage

overloading of the inverter

overheating (cooling fan not working).


Needed as the load humming is happening

1. whats the battery voltage and dc amps being drawn

2. whats the AC output voltage and amps and or watts being used.

3. as its off grid whats charging the batteries and how is it connected

4. what exactly are the flashing lights doing

5. a diagram of how everything is connected would also help
