Parallel and three phase systems
The configured AC input current limit is the total
limit per phase.
4.3.4.2 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.
On the CCGX 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:
And also it will be listed in the Alarm Log on VRM,
and an email will be sent; using the VRM Alarm
Monitoring system.
4.3.4.3 Grid failure monitoring
When this feature is enabled, an alarm is raised when
the system hasn't been connected to the AC input
configured to be Grid or Shore for more than 5
seconds.
The alarm shows as a Notification in the GUI, and as
an alarm on the VRM Portal, and is available on
ModbusTCP / MQTT.
Recommend to use for backup systems. But also for
yachts or vehicles on shore power.
Note that this settings monitors that the system is
connected to grid/shore. Generator monitoring is
already available as part of the Generator start/stop
function and not part of this.
Do not use this feature in systems that use the Ignore
AC Input settings in our inverter/chargers: when the
system ignores the AC input, ie runs in island mode,
as intended, even though grid is available, it will
report a grid failure.
