Quattro 5KVA + Autotransforemer

Hi guys,


I have a problem with my installation. Suddenly, the output voltage drops from 120V to 60V for 5 seconds, after that, everything is still working normally. It has this kind of behavior at least twice a month. fault.jpg

What can be the cause of this problem? It could be a programming issue?

BTW, I have a 5kva Quatro system, working with an autotransformer and 2 liyhium batteries of 200A at 48Vdc. The System is setup to ignore the grid trough virtualswitch configuration.
