A three phase Multiplus-II 48/3000 system goes into overload for 60~120Seconds almost every day, however, the notification area does not show the overload warning. We can see the overload condition on the advanced graphs as well as in the downloaded XLS file. In the XLS file it shows “Warning” while the system is in overload in the column “VE Bus Overload”.
If you are running the new gui, under the inverter in device list - alarn set up, you will see a way to configure whether you have warnings and alarms or not.
