10.2. Phase rotation warning
The AC supply, either Generator or Grid, to a three phase inverter/charger system needs to be in the correct rotation, also known
as sequence. If not, then the inverter/chargers will not accept the AC supply and remain in Inverter mode.
The Phase rotation warning will be raised in such case. To resolve the issue, change the wiring on the AC input: swap either one
of the phases, effectively changing the rotation from L3 → L2 → L1 to L1 → L2 → L3. Or reprogram the Multis and modify the
phase assigned to match the wiring.
On the GX device itself, the warning will popup as a notification on the GUI:
Also, it is visible in the menus:
On the VRM Portal, it is visible in the VE.Bus Alarms & warnings widget on the Advanced page and will be listed in the Alarm Log
on VRM. Furthermore, an email is sent; using the VRM Alarm Monitoring system.
