VE.Bus Error: VE.Bus Error 24: Switch-over system protection initiated

Hey everyone, I’m having an issue with an alarm on my Quattro 15kVA (VE.Bus Error: VE.Bus Error 24: Switch-over system protection initiated) . The system was working fine until this alarm appeared. Does anyone know the cause or solution for this? I tested with my multimeter (continuity mode) and found a short between the input and output after the alarm showed up.

Hi, error codes are quite well documented.
