3.2 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 be popup as a notification on the GUI:
Also, it is visible in the menus:
And on the VRM Portal, it is visible on the VE.Bus Alarms & warnings widget on the Advanced page:
